Mac OS X Yosemite: Pictures And Features Of Apple's New OS

So here it is, Apple has unveiled Mac OS X Yosemite at WWDC 2014. The new-but-also-slightly-the-same update brings Macs and MacBooks visually more in line with Apple's iOS mobile operating system.

Mac OS X Yosemite comes out in September for free.

Unveiled at WWDC 2014, Mac OS X Yosemite is an update that adds new features such as the ability to make phone calls via your Mac and wirelessly send files between your iPhone and Mac.

There's also an improved notifications centre and all-new versions of Apple Mail and Safari.

In case you're worrying that it'll be changed beyond recognition then fear not as this is as much about fixing all the things you hated about Mac OS X whilst adding some incredibly powerful new features.

Here's some of Mac OS X Yosemite's best features:

New UI: Yosemite now comes with a transparent UI that echoes that of iOS 8.

Spotlight: Spotlight on Mac OS X Yosemite now features contextual answers including real-time conversion.

Cloud Drive: Apple is taking on Dropbox with its own in-Mac cloud drive that you can drag files to on Mac, iOS and Windows.

Safari: Mac OS X Yosemite now features a new Safari app which massively increases battery life by up to two hours.

Handoff: Mac OS X now comes with Handoff, a contextual app that lets you instantly switch between devices when using an app, whether it's writing a message or editing a word document.

Instant Hotspot: Instantly create a Hotspot between your iPhone and MacBook without having to enter any details.

Phone calls: Yes you can now make phone calls on your MacBook or iPad via your iPhone. It'll simply pop up on your Mac or MacBook letting you answer the call and take it, through the laptop.
