Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.

To check the model number hold down the option/alt key, go to the Apple menu and select System Information.

  • MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
  • MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher


Your Mac needs:

  • OS X v10.6.8 or OS X Lion already installed
  • 2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
  • 8 GB or more of available space
