Cool Instagram Tips And Tricks

Cool Instagram Tips And Tricks

1. Save Original Instagram Photos

Most of the applications that help us to share media, do so by compressing our images. Even though this is in the best interest of users as compressed images lead to less data usage, a simple fact is that some people don’t wish to part with their high quality images. The easy way out that Instagram found for its users is to save their original images. This is an option that Instagram provides in the option menu.
To access this option, all you need to do is to open your Instagram account and go to your profile, and in your profile tap on the three dots that symbolize options on the top right.

Save Original Instagram Photos  1

Upon clicking you’ll see a lot of options, but if you look for the option that says Save original photos, then you would be able to keep with you the original high quality photos that you clicked on your mobile device.

2. Keeping Your Instagram Account Private

Not everyone on Instagram is open to showing their pictures to random people on the internet, but when you create an Instagram account, you go on to publicly share every possible photo that you post.
Instagram addresses this issue with an option that helps user to keep their account private. What it’ll do is that it will leave you in charge of the people who’ll then be allowed to follow you. But as we know, when our account is not private, practically any possible person can start following us. So, making your account private would be the best deal if you don’t wish random people to follow you and stalk your profile.

Keeping Your Instagram Account Private
To turn your account to private, you’ll again need to go to the options menu through your profile page on the mobile app, and then turn on the option that says Private Account.

3. Saving Data While Using Instagram

Are you one of those who are always low on data? Or maybe you wish to use Instagram without feeling guilty about the amount of data that is sucked by the app. A good solution to these issues is the option option of using less data that Instagram provides. For this, you’ll need to go to the options menu and then tap on Cellular Data use.
Tapping on cellular data use will provide you the option that says Use Less Data. Tap on this option for efficient data usage.

4. Adding Hashtags After Posting The Photo

A lot of times it happens that we forget to put the hashtags that we intended to put in our posts. Instagram does not allow us to edit what we have written in our posts like Facebook does, so instead of worrying over the hashtag that you missed, what you can do is that you can post those required hashtags in a comment below your post. They’ll work in the same way as your hashtag in the description works.

Adding Hashtags After Posting The Photo
As you can see, hashtags are there in the comments section in the image above.

5. Geo-tagging In Instagram

It is rare that we forget the place where we clicked a picture, but if you have people asking you the same again and again, then what you can do is that you can geo-tag the images that you post. Geo-tagging is nothing but a way to tag the picture with the place where you clicked it.
For this, whenever you share a photo, just select the option that says Add to Photo Map, and your image will be saved to the photo map and you and others will then be able to see the place where your picture was clicked.

6. Linking Your Instagram Account to Other Social Media Accounts

Instagram allows you to link a number of social media accounts, so that you can share your posts straightaway with your loved ones or with your followers.

Linking Your Instagram Account
The accounts that one is allowed to link with Instagram include Facebook, Twitter, Foursquare, Tumblr, Flickr and VKontakte. These are the accounts that are available on an android device, other OS may allow to link some different set of accounts.

7. Removing A Tag on Instagram

Many of us get tagged by our friends in silly images, and these pictures show up on our tagged page, Instagram has a solution to cope with this issue as well, but for this, you would first need to go to the image that you are tagged in. Once you have opened the image, tap on 3 dot button symbol (symbolizing options) on the bottom right, upon clicking, you’ll see an option that says Photo Options, click on it and you’ll see further options. Now at the last stage, you’ll need to look for the option that says Remove Tag, press it to straightaway remove the tag from that photo.

8. Removing Tagged Instagram Images From Photos of You

What happens if we have an unnecessary tag and we want to remove it from our profile, i.e. from the area where Photos of You are shown, but a small catch in this case is that you cannot remove the tag as you don’t want your friend to feel bad?

Removing A Tag on Instagram
A way to do this is by first going to the options in the tagged photo, and then tapping on Photo Options. At the last stage, we’ll see the option of selecting whether we want to keep the photo in Photos of You or not. If you decide not to check it, the particular photo will be removed from Photos of You, but the tag will stay intact.

9. Sending Instagram Photos Privately to Your Friends

Instagram also works as a messaging service for photos and videos, for instance, if you wish to send images directly to certain friends of yours, then you can use Instagram direct. For opening Instagram direct, you first need to go to the home option that you have on the main screen of the Instagram, and then you’ll need to tap on a drawer like image on the top right corner, pressing it will open Instagram direct.

10. Use Instagram As Photo Editor

Instagram can also be used as a photo editor; all you need to do is put your phone on flight mode and then click pictures using Instagram, edit them and publish them. An error will come up saying that the upload failed, but in your gallery you’ll be able to find the edited images.
                 Use Instagram As Photo Editor

11. Print Your Instagram Photos on A Poster

You can get your Instagram photos printed on a poster, all you need to do is to visit myyearprinted.com, and click on Connect with Instagram.
Upon clicking on Connect with Instagram and then upon authenticating, you’ll be asked to select the users whose pictures you would want to have on a poster. Clicking on any of the users would display all the pictures posted by that user in a specified time frame. Now you’ll be asked to select the images from the images provided on the screen, so that they can be added to your poster. If you don’t select any image, all the images presented to you on the page will appear on the poster.

Print Your Instagram Photos on A Poster
The final step is to select the size of your poster, and to order it by paying a specific amount.

12. Combine Multiple Instagram Photos into A Single Image/ Make A collage

Guys at Instagram must have seen the craze that people have with making collages, and thus they came up with another app called Layout. This app allows you to put a number of pictures in a single image, or in other words, allows you to make a collage. Just download this app to let the magic unfold.
First of all you would need to select the images, next up you’ll need to decide a layout for them, and finally you would be given the option to make edits namely mirror, replace and flip. You can then share the picture wherever you want.

Combine Multiple Instagram Photos
Note: One should keep in mind that Layout app is not Instagram specific, so you can use it for other images on your phone as well. Also, the app has recently been made available to Android platform.
Availability: Android , iOS 

13. Create Amazing Time Lapse Instagram Videos

Hyperlapse is another application by Instagram which is currently available only for iOS, it allows a user to create beautiful time lapse videos. The speed of the video can be adjusted and the best part about this application is that it stabilizes the time lapse video that one makes, so one can get really beautiful without using a tripod or a professional photographic equipment.

14. Discover The Best Content on Instagram

An app which does the above mentioned thing like a charm is Huntgram. As of now, Huntgram is available only for iOS. What it does is that it helps you to tailor fit your Instagram feed according to the country, category, hashtag and many other preferences.

Huntgram 
For instance, you can also filter pictures and users from each country, moreover, different categories section features topics like Animals, Art, Nature, Architecture, Animals and many more. You can also look for the most influential users on Instagram using this application. Its publisher mentions that Huntgram is an application that can help you find what you want in a fast and easy manner, and it is quite evident from the description that the words of publisher are what this app stands by.

 Thanks

Apple iPad Air 2 Review

Apple iPad Air 2 Review

Price 
£332.50 (16GB, WiFi-only)
Pros 
Unbelievably slim and light; Great design;
Cons 
Expensive; iCloud sharing has some problems; No waterproofing
Verdict 
Not a must-have for owners of the original iPad Air, but a great buy for owners of older iPads and first-timers
UPDATE: 
If you're looking for something to pair with Apple's thinnest-ever tablet, how about its thinnest-ever laptop? The Retina MacBook is a gorgeous feat of engineering, and you can read our full review of it right here.
The iPad Air 2 is the sixth version of Apple’s 10in tablet in four years, so it’s easy to become indifferent to what is still a technical marvel. A computer, camera and camcorder in a metal casing that weighs just 437g and is connected to the internet wirelessly would’ve been unfeasible just a few years ago.

iPad Air 2 review: design, display and battery

The Air 2 looks almost identical to its predecessor, but it’s 1mm thinner than before and just over 30g lighter. We scoffed at such small changes in dimensions on paper, but they’re surprisingly noticeable in the flesh. With its lighter, more evenly distributed weight and thinner profile the Air 2 is much more comfortable to hold than its already slender predecessor - especially for long periods of time.


We were also sceptical about Apple’s claims that the 10in screen is less reflective, but once again the difference was noticeable. Compared to other tablet screens, it was considerably less reflective under both domestic halogen lighting and fluorescent office lighting strips. This means it’s less likely you’ll have to change your seating position or turn down the lights just to avoid seeing your reflection while attempting to read to watch a video. Contrast and colour accuracy are both excellent - the only tablet display that’s as good is the one found on the Samsung Galaxy Tab S 10.5 which has more vibrant colours.
The Air 2’s thinner build means that the battery is a little smaller than before, which we feared would result in noticeably shorter battery life. This wasn’t the case though with the battery lasting ten and a half hours when playing videos - the same lengthy score achieved by the original iPad Air. However, rival tablets can last even longer - the Tab S 10.5 lasted 14 hours and 20 minutes for example, while the Sony Xperia Z2 Tablet lasted a staggering 16 hours.

iPad Air 2 review: hardware, performance and connectivity

Part of the reason for the Air 2’s lengthy battery life is its power-efficient triple-core processor, the 1.4GHz A8X. It’s also very fast, excelling in our 3D graphics tests as well as our app and webpage loading benchmarks. Paired with 2GB of memory, it makes the Air 2 one of the fastest tablets we’ve seen so it should have no trouble running demanding apps for some time to come.
We suspect most people will opt for the WiFi-only version of the Air 2, but if you do opt for the 4G variant then there’s a potentially handy new feature called Apple SIM. This SIM card can, in theory, be used with any mobile network so you can take advantage of the best mobile broadband deals by simply selecting the network and package you want in the Settings app instead having to order, wait for and swap SIM cards.


However, for now the only UK network that works with Apple SIM is EE, whereas Americans have their choice of almost all the major nationwide mobile networks in the US. Hopefully, the other UK networks will become compatible with Apple SIM soon. You can of course use a standard nano SIM with a 4G Air 2 and the Apple SIM is still useful if you’re travelling in the US and want to have mobile broadband as British visitors can sign up for one month plans with T-Mobile US.
Although the new fingerprint reader isn’t as useful here as it is on an iPhone, which is more likely to be lost or stolen due to its smaller size, it’s still a useful feature to have on an iPad. Whether you’re worried about data security or simply want a more convenient way to unlock your tablet, the fingerprint reader worked flawlessly.

iPad Air 2 review: camera, iCloud and iOS 8.1 

We feel very conspicuous taking photos using a tablet, but many other people share no such inhibitions. We’ve seen tablets used as cameras from the streets of London and Rome to the Jordanian desert. The Air 2’s camera coped well in brightly lit conditions capturing surprisingly sharp and detailed photos. It’s not as good as the iPhone 6 or 6 Plus for low light photography where its photos aren’t as sharp or well-lit and have more noise, but the Air 2 is still a respectable camera to fall back on.
There are lots of new features in iOS 8, Apple’s latest mobile operating system, and one of our favourites is Continuity. This lets you use different iOS devices together more efficiently and now work with Macs too. For example, you can now instantly share the Air 2’s 4G connection with your Mac without fiddling about with settings and you can reply to iMessages using your Mac’s keyboard.
You can even start tasks on your iPad, such as writing a long document or working on a spreadsheet, and finish them on your Mac picking up right where you left off. It’s a shame but unsurprising that these useful features aren’t available for Windows, but even if you do have a Mac most of the Continuity features rely on your Mac having built-in Bluetooth 4.0 or require apps to specifically support them.

One feature which does work with Windows is iCloud Drive, Apple’s equivalent to online storage services such as Dropbox and is used for sharing files between the Air 2 and your other computers. You get 5GB free, but this is shared with any other iCloud services you use such as iCloud email. Extra storage is reasonably priced starting at 79p per month for an extra 20GB.
However, iCloud Drive does have some odd limitations. While it works with Windows 7 and 8, it only works with Mac OS X Yosemite and not any older versions of Apple’s own desktop operating system. Plus, there’s no currently no way to share a large file with non-iCloud Drive users by creating a link as you can with Dropbox. In any case there’s little reason to use it if you already use other storage services as apps updated for iOS 8 can now access other storage services more easily than ever before. Plus, if you want to share files between your iOS 8 devices and Macs without using the internet you can do so using the revamped AirDrop wireless file sharing feature.

iPad Air 2 review: conclusions

Each of the iPad Air 2’s new features seem minor on paper, but taken together they all add up to help make it one of the best tablets available – it’s simply a joy to use. If you want the longest possible battery life though or if you want waterproofing then the Sony Xperia Z2 Tablet is a better pick despite its inferior screen and camera.

Specifications 
OS: iOS 8.1
Display: 9.7in 2048 x 1536 display
CPU: 1.4GHz Apple A8X triple core processor
RAM: 2GB
Storage: 16GB
Dimensions: (WxHxD) 170 x 240 x 6mm
Weight: 437g

Best smartphones to buy in 2015

Best smartphones to buy in 2015

 

Android, BlackBerry, iOS or Windows Phone? Find out which is best for you

Whether you're an IT admin looking to deploy devices or an end user ready to upgrade to your next flagship phone, there are plenty of handsets on the market to choose from.
All major manufacturers from Apple through to Sony and Samsung are expected to release updated versions of their respective flagship handsets this year - so stay tuned as we update the list throughout the year.
Here we count down the 10 best smartphones available to buy so far in 2015:

10) BlackBerry Passport - BlackBerry 10

Desperate times resulted in BlackBerry chancing a radical redesign. Despite the weird look, the Passport offers a beautiful 4.5in display, which you never have to turn in landscape mode thanks to its square design. It's also got mammoth endurance thanks to the 3450mAh battery pack and allows you to install Android apps.
The BlackBerry Hub remains one of the best notification aggregates on any mobile operating system - making it ideal for messaging addicts.
Key specs - 4.5in LCD display (1440 x 1440), 2.2GHz quad-core processor, 3GB RAM, 32GB internal storage + micro SD support (128GB), 13-megapixel camera, 196g
Pros - Great screen, battery life, ability to install Android apps
Cons - Big and bulky, keyboard takes a while to get used to
Price - Free from £30.50 per month or £530 SIM-free
------------------------------------------------------------------------------------------
Windows Phone devices are slowly gaining traction within businesses thanks to the inclusion of software such as Office, Skype and OneNote.
The Lumia 930 is beautifully crafted and the soft-touch polycarbonate back panel makes this the most comfortable smartphone we've tested to-date.
Performance is smooth with zero stuttering as Windows Phone has been optimised to run beautifully on mobile hardware. The major drawback is the lack of apps in the Windows Store.


Key specs - 5in AMOLED display (1920 x 1080), 2.2GHz quad-core processor, 2GB RAM, 32GB internal storage, 20-megapixel camera, 167g
Pros - Great design, good camera, wireless charging included
Cons - No micro SD expansion, Windows Store is behind Android and iOS, battery sealed in
Price - Free from £26.50 or £400 SIM-free
------------------------------------------------------------------------------------------
The HTC One M9 retains the same design as its predessor, the HTC One M8, but has undergone an update, not least of all to Lollipop.
fter much criticism for its low-res images, HTC has switched the 4-megapixel UltraPixel sensor around to the front, using a (reported) Toshiba 20-megapixel sensor on the rear. This makes it one of the highest-resolution cameras around, although when shooting ‘standard’ 16:9 shots it actually crops into the sensor resulting in roughly 16-megapixel images.


Key Specs -  5in 1080x1920 Super LCD3 IPS, Qualcomm Snapdragon 810 2GHz octo-core, 3GB RAM, 32GB internal storage + micro SD card support (128GB), 20-megapixel rear camera, 4-megapixel front camera, 157g
Pros - Great design; Strong speakers; Tasteful software
Cons - Conservative screen; Inconsistent camera; Disappointing battery life
Price - From £39 per month (contract)
------------------------------------------------------------------------------------------
LG produces underrated devices with the G3 packing a superb design and numerous features.
USPs include a laser-guided 13-megapixel camera, a well-designed Android overlay and the ability to unlock the phone with a customised tapping sequence.
The LG has a beautiful 5.5in display (2560 x 1440) but we're not fans of the artificial sharpening. This can make text awkward to read on some backgrounds and is the primary reason the device isn’t higher up the list.

Key specs -  5.5in LCD display (2560 x 1440), 2.5GHz quad-core Qualcomm processor, 2 or 3GB RAM, 16/32GB internal storage, 13-megapixel camera with laser guidance, 149g
Pros - Solid performance, well-designed, great camera, removable battery
Cons - Display sharpening
Price - Free from £26.50 per month or £480 SIM-free
------------------------------------------------------------------------------------------
.
6) Apple iPhone 6 - iOS 8
Even the most ardent Apple fan will admit that previous iPhones were too small when it came to browsing and watching video comfortably. At 4.7ins, the iPhone 6 achieves balance between size and comfort.


As with all iPhones, build quality is superb, the 8-megapixel camera is top notch but the lack of optimal image stabilisation is a miss.
However, the battery life isn’t great - and this won’t last as long as its bigger brother. And the display isn’t full HD with Apple opting for a 1334 x 750 resolution.
Key Specs - 4.7in LED-backlit LCD display (1334 x 750), Apple A8 processor + M8 co-processor, 1GB RAM, 16/64/128GB storage, 8-megapixel rear camera, Touch ID, Apple Pay, 129g
Pros - Good size, great camera, beautiful design, feature rich iOS 8
Cons - Screen not full HD, battery life could be better (non-removable), expensive
Price - Free from £58.50 or £539 SIM-free
------------------------------------------------------------------------------------------
Many firms have tried to miniaturise their flagship handsets, but have ultimately had to sacrifice performance to keep the price down. But with the Xperia Z3 Compact, Sony has managed to squeeze all the premium features into a small 4.6in form factor.
The Z3 Compact uses the same high-end quad-core 2.5GHz Qualcomm 801 chipset you’d find in the bigger Z3 model. It’s got a 20-megapixel snapper and battery life is superb, as you’d expect from the Xperia range.


Plus the Z3 Compact retains the Waterproof rating so it can be submerged in 1.5 metres of fresh water for up to 30 minutes.
A excellent choice if you want a sub-5in smartphone.
Key specs - 4.6in LCD display (1280 x 720), 2.5GHz quad-core Qualcomm processor, 2GB RAM, 16GB internal storage + micro SD support (128GB), Waterproof up to 1.5 metres, 20.7-megapixel camera, 129g
Pros - Solid performance, phenomenal battery life, robust design
Cons - Battery not replaceable, glass back will require a cover
Price - Free from £26.50 per month or £430 SIM-free
------------------------------------------------------------------------------------------

The Huawei P8 is a cracker of a phone. Not only does it look the absolute business, it’s a breeze to use. Die-hard Androidites might take umbrage with their beloved OS being ‘Appled-up’, but it’s undeniably slick.
It’s not got the best screen around and the ‘knuckle sense’ software throws the occasional wobbly. However, it makes up for it with possibly the best camera we’ve ever seen on a mid-range device.



Key Specs - 5.2in IPS display, Kirin 930 2/1.5GHz octacore CPU, 3GB RAM, 16/64GB internal storage, 13-megapixel camera, 144g
Pros - Excellent design; Spectacular camera; Very capable display
Cons - 'Knuckle Sense' sometimes interferes with touch controls; Could be a little cheaper
Price - Starting from around £359

3.Samsung Galaxy S6 - Android Lollipop 5.0 + TouchWiz overlay
 




The Galaxy S6 is not a cheap phone. It’s an expensive phone. But is also appears to recognise that in a market where lower-cost phones are starting to offer an experience fairly similar to much more expensive ones, something special is needed to justify an outlay of £550.
A great fingerprint scanner, construction that is leagues ahead of any previous Samsung flagship and a very reliable, high-quality camera make it a very compelling upgrade. It has none of the air of disappointment seen in some annual updates and counters almost every criticism levelled at Samsung phones bar the usual software bloat.
Key Specs - 5.1in Super AMOLED display (2,560 x 1,440), eight-core Exynos 7420 2.1GHz, 3GB RAM (no MicroSD support), 32GB/64GB/128GB on-board, non-expandable, 16-megapixel camera, heart-rate sensor, fingerprint scanner, 138g.
Pros - Superb screen; High-quality construction and feel; Efficient and powerful processor; Very good fingerprint scanner
Cons - Non-expandable memory
Price - £549

With a mammoth 5.5in display, the 6 Plus is the biggest iPhone you can buy.
Standout features include the phenomenal full HD display (1920 x 1080), which has been labelled as the best LCD screen on the market by DisplayMate.
The 8-megapixel camera introduces Focus Pixels - so autofocusing is so fast you can snap away without worrying about blurry images.


And thanks to the extra space in the chassis there’s a 2915mAh battery. This is the first iPhone where you won’t have to worry about charging the device midway through the day.
Being Apple’s first foray into the phablet market, the design is one of the surprising letdowns. The 6 Plus feels too bulky in comparison to something like the Note 4. "Bendgate" isn’t as a big a deal as has been reported - so unless you wear skinny jeans, or you're Uri Geller, there's unlikely to be a problem.
It would have placed higher if it had a more compact design because in its current form it’ll be too big for some users.
Key specs - 5.5in LCD display (1920 x 1080), 1.4GHz dual-core A8 processor + M8 co-processor, 1GB RAM, 16/64/128GB internal memory, 8-megapixel, Touch ID, Apple Pay, 172g
Pros - Best iPhone battery life to-date, Fantastic screen and camera
Cons - Too big and bulky for some, expensive, sealed in battery
Price - Free from £48.50 per month or £619 SIM-free



The latest effort from Samsung is also its best. Power users wanting the best display, battery life and performance need not look any further.
With some engineering brilliance, Samsung has packed in a 5.7in display into a slim-form factor. The Note 4 is smaller than the iPhone 6 Plus despite the Samsung device having the larger screen.


The Note also includes the S-Pen stylus for those who want to take notes, make annotations or tweak designs on the move.
Battery life is unmatched with a mammoth 3,200mAh cell and there’ll be plenty of longevity as the device has a quad-core processor and 3GB RAM.
Of course, the Note 4 isn’t perfect. Samsung’s TouchWiz overlay isn't for everyone, and it’s not got the waterproof rating of the S5. But it’s still the best you can buy at present.
Key specs - 5.7in Super AMOLED display (2560 x 1440), 2.7GHz quad-core Qualcomm processor (Exynos Octa-core in some regions), 3GB RAM, 32GB internal memory + micro SD card support (128GB), 16-megapixel camera, fingerprint scanner, heart rate monitor, 176g
Pros - Stunning display, smooth performance, great battery life, pen input
Cons - Software can be overwhelming, not waterproof
Price - Free from £39.50 or £650 SIM-free

Discover hidden tips & tricks in Apple's OS X Mavericks, including shortcuts and security.

Discover hidden tips & tricks in Apple's OS X Mavericks, including shortcuts and security. 

  Whether you're new to the Mac platform or have been using it for a number of years there are always tricks and tips you may be unaware of, which can boost productivity.

Below we list 14 tips and tricks to help you get the best out of Apple's desktop operating system.

1. Useful shortcuts
If you’re coming across from a Windows machine you’ll need to adapt to the new shortcuts on Mac. There are bucketloads of features so we've included ten useful ones to get you started.

Command + Tab  – Cycles through apps
Command + `  – Switches between application windows
Command + ,  – Opens up application preferences (may not work with everything)
Command + H – Hides current window
Command + Option + Esc – See running apps and force quit if necessary
Shift + Command + 3 – Screenshots entire screen and saves as a picture
Shift + Command + Control + 3 – Screenshots entire screen and is copied to clipboard
Shift + Command + 4 – Screenshot a designated area with the mouse
Option + Shift + Command + V – Pastes text with no formatting
Option + Shift + Command + Space - Opens a windows with spotlight so you can search for files on the Mac.
2. Make sure TrackPad gestures are activated
If you’re using a MacBook then chances are you’ve got the gestures sorted. If you’re using a desktop it’s a good idea to invest in the Magic TrackPad accessory so you can also benefit from smooth transitions between apps, desktops and windows.
We prefer unticking the natural scroll direction - but it’s worth experimenting to see what you find comfortable.




3. Screencast recording
OS X has a built-in screen recording facility allowing users to capture everything on the display. This is handy for making instructional videos and can even be useful in compliance situations. To record a video open up QuickTime Player and from the file menu, click on “New Screen Recording”. Then choose the audio source such as the internal mic and whether you want to include mouse clicks.
When ready, hit record and make your video. It’s possible to record the whole screen or a selection. Afterwards, you can edit it and upload it to YouTube.

4. Resize, crop,  fine-tune images & add a signature
The Preview app is more than just an image viewer. It can crop, edit and adjust the colours of an image/
From OS X 10.7 onwards, the Preview app allows you to add your signature to documents and mail them digitally.
In Preview preferences, navigate to the Signature tab and click on the “+” button. Write your name in black ink on a blank sheet of white paper and hold it to the Mac’s webcam, and watch as it magically appears onscreen.
To put your signature to a document, bring up the Edit toolbar and click on the signature icon. Draw a box and add your signature to the form. You printing, signing and faxing days will be a thing of the past.




5. Dictation
Voice dictation was built into Mountain Lion and has now been improved within Mavericks.
To enable dictation, go the System Preferences and choose “Dictation and Speech” and make sure the radio button for Dictation is “On”. Then to use dictation, just press the Fn key twice in succession and start talking. You can also change this shortcut to whatever combination of keystrokes works best for you.
In Mavericks, there is an “Enhanced Dictation” tool. Clicking on the check box downloads a 700MB language file so all speech processing is done on the Mac locally instead of through Apple's cloud servers. This also means the thirty-second limit on speech you dictate is no longer applicable and you can chat to your heart’s content.
6. Add website clips to Dashboard
Dashboard is the half-forgotten feature of OS X and only ever pops up when you accidentally swipe too far left.
You can add web pages as widgets and put them on the dashboard for future reference. To do this, open up Safari and make a clip of a website, open it in Safari, then choose “Open in Dashboard”. Use your mouse to select the area of the webpage you want on the dashboard and then click add (on the top right of the window).
This then puts the clipping onto the dashboard (there’s an “I” in the bottom right of the clip that allows you to change the frame appearance). The clip should automatically update, but if it doesn’t appear to Command + R will refresh the clip.
7. Kill the Dashboard
Perhaps having web clips isn’t your thing. You can get rid of the Dashboard by opening up the Terminal app and typing “defaults write com.apple.dashboard mcx-disabled -boolean true”, then hitting enter. Relaunch the dock by typing in “killall Dock” and you'll never see this feature again.

8. Remote control a Mac
OS X has a built remote sharing feature called Back To My Mac.
You need to ensure the Mac you want to remotely connect to is on and synced with your iCloud account (this is done via the Systems Preferences app). You should also make sure that Back To My Mac is enabled by ticking the box. In the sharing preferences part of system preferences, make sure the remote management is enabled on the Mac you need to connect to as well. On the router the remote Mac is connected to ensure that UPnP is enabled. All of this should then allow your remote Mac to check in with Apple’s server to let them know its internet location.




From the Mac you are working on make sure that iCloud is turned on and you are logged in with your account to that service, turn on Back To My Mac as well as sharing. It’s important to make sure you are using the same Apple ID on both computers. Then it is just a case of clicking on the remote Mac on the sidebar in a Finder window and clicking on Share Screen. A window will open and display the remote Mac’s screen.
9. Copy Files to and from a remote Mac
Back To My Mac not only lets you share the screen but lets you copy files to and from a remote Mac. If you have followed the previous process to share the screen, to access files, you need to enable File Sharing under the Sharing icon in System Preferences.
In the Finder window go to the remote Mac you wish to share files with and you click on “Connect As”. Type in your Apple ID and password and now you have access to the hard drive. You can move files between the two systems as you would with a remote server.
10. Merge all finder windows
This is one for Mavericks users. Finder now supports tabs so you can consolidate multiple panes into one window. Instead of dragging them all together one-by-one, in the Finder menu choose Window the click on Merge All Windows and you're done.





11. Share a DVD drive with others

The latest Mac desktops and laptops don't have optical drives but it you need to use physical media it's still possible. If you have an old Mac with a Super-drive you can set it up to share this with your drive-less devices.
To do this, open up System Preferences on the Mac with a DVD drive, click on Sharing and in that window tick the box marked “DVDor CD sharing”. Then insert the disc you want to share. Go the drive-less Mac (making sure it is on the same network) and open the Finder window. Look at the sidebar for “Remote Disc” in the Devices section. Click on it and then double-click the computer you want to connect to.

12. Find another printer 
Working in a large department you may find a printer to be busy churning out a large document. You can set up your Mac to print to the next available printer if there is more than one on the network. To do this, go into System Preferences and click on Printers and Scanners.
Select the printers from the list that you want to be in the pool (To select multiple printer, hold down the Command button and click on additional printers. Click on Create Printer Pool and give it a name. Click OK.
Then next time you print a document, you can choose the printer pool from the pop-up menu.

13. Give your guests safe access to a Mac
Guest accounts are great if you want to let someone borrow your Mac to check email or browse the web.
This can be enabled by going into System Preferences and clicking on Users and Groups. This then puts the Guest User account on the login screen. Guests can use this account and once finished it wipes that session.
14. Find out what your Mac is up to
Sometimes you may find the Mac is running slow and you have no idea why. There is a handy little app that lets you see what exactly is going on under the hood.
Activity Monitor can be found in the Utilities Folder. This has columns showing CPU usage of individual apps and processes and how much memory it is using. If you find a problematic app hogging resources, you can click on Quit Process to shut the offending app down. You can also use this utility to look at usage graphs as well.
