Apple start showing off Yosemite, Sam
Apple will dripfeed everyone with their new operating system, Yosemite, as of tomorrow.
OS X Yosemite was announced in May, and now it will be available as a public beta test, which will kick off around 1pm EST (which is around 6pm in the UK). If you want to test it out, then hit this link and sign up.
So what's new? Well, Yosemite will use translucency throughout the system, so if you didn't like the 'flat' colourful UI design of iOS 7, you'll probably hate this.
There's also a thing called 'Handoff', where Yosemite and iOS 8 will work easier with each other. If you start work on your iPad, it'll be simpler to pick up where you left off on your Mac (and vice versa). You'll be able to answer phonecalls from your iPhone with Yosemite too.
There's improvements to iCloud and the Mail app too, and AirDrop will now work between iOS and Mac devices.
There's a load of other new things going on as well, but we advise that, if you're really interested in all that, you let Apple tell you all about it, here. The short version is that Apple want to hook your iPhone up with your other devices in a way that is much easier for the user.
