We previously told you the iOS devices compatible with iOS 8 (sorry, iPhone 4 owners). Here’s what you need to know about OS X 10.10 Yosemite compatibility:

To upgrade to OS X 10.10, you’ll need a Mac that can run OS X 10.8 Mountain Lion or OS X 10.9 Mavericks. This doesn’t mean that all the OS X Yosemite features will run on your Mac. Unfortunately, Apple has yet to announce which features won’t run on older models.

To run OS X Yosemite, your Mac needs to have 2 GB of RAM, 8 GB of available disk storage, and at least OS X 10.6.8 already installed on it. Like OS X Mavericks, OS X Yosemite will be available as a free download on the Mac App Store.

The list of OS X Yosemite-compatible Mac models, courtesy of ArsTechnica, is as follows:

  • iMac (Mid-2007 or later)
  • MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
  • MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
  • MacBook Air (Late 2008 or later)
  • Mac Mini (Early 2009 or later)
  • Mac Pro (Early 2008 or later)
  • Xserve (Early 2009)

Apple will release OS X Yosemite later this year. The company is still accepting applications from non-developers to be a part of its new OS X Beta program. For more information, click here.
