Apple will release their new operating system OS X 10.10 Yosemite between September-November this year.

 

At this stage of the game the new OSX will run on pretty much the same machines as its predecessor OSX 10.9 Mavericks. You’ll need a 64bit Intel processor, 8GBs of free disk space – if upgrading as appose to clean install min. of OSX 10.6.7 required plus 2GB of RAM.

The Good

• iMac – all models from mid 2007, iMac 7,1 – 12,1
• MacBook 5,1 – 7,1
• MacBook Pro  3,1 – 8,3
• MacBookAir 2,1 – 4,2
• Mac Mini 3,1 – 5,3
• Mac Pro  3,1 – 5,1
• Xserve 3,1

Which means most devices made prior to 2008 won’t be able to run it.

The Bad

– OS X 10.10 Yosemite won’t run on –

• iMac 4,1 – 6,1
• MacBook  1,1 – 4,1
• MacBook Pro 1,1 – 2,1
• MacBookAir 1,1
• Mac Mini 1,1 – 2,1
• Mac Pro  1,1 – 2,1
• Xserve  1,1 – 2,1
