Mountain Lion, which is available now in the Mac App Store, can only be installed on the following Mac devices:
- iMac (Mid 2007 or newer)
- MacBook (Late 2008 Aluminum, or Early 2009 or newer)
- MacBook Pro (Mid/Late 2007 or newer)
- Xserve (Early 2009)
- MacBook Air (Late 2008 or newer)
- Mac mini (Early 2009 or newer)
- Mac Pro (Early 2008 or newer)
We cannot stress this enough: If your Mac isn’t on the list, you cannot upgrade.
One of the coolest features in Mountain Lion is also the one that won’t work on most Macs. AirPlay Mirroring requires a second-generation Apple TV or higher. Additionally, it is only supported on the following Mac devices:
- iMac (Mid 2011 or newer)
- Mac mini (Mid 2011 or newer)
- MacBook Air (Mid 2011 or newer)
- MacBook Pro (Early 2011 or newer)
Those will older Macs, however, do have a third-party solution for AirPlay Mirroring. For $10, you can use AirParrot.
Power Nap, another nice OS X feature, is only usable on the MacBook Air (Mid 2011 or newer), and the MacBook Pro with Retina display.

We hope this report helps you determine whether OS X Mountain Lion is right for you.
