Which OS for which Mac ?

MacOS Mojave (10.14)

You can upgrade to macOS Mojave from OS X Mountain Lion or newer on the following Mac models:

  • MacBook (early 2015 or newer)
  • MacBook Air (mid-2012 or newer)
  • MacBook Pro (mid-2012 or newer)
  • Mac mini (mid-2012 or newer)
  • iMac (late 2012 or newer)
  • iMac Pro (2017)
  • Mac Pro (late 2013, plus mid-2010 and mid-2012 with Metal-compatible GPU)

MacOS High Sierra (10.13)

Apple announces compatibility of this OS with MacBooks and iMacs from 2009 or later. All MacBook Airs, MacBook Pros, Mac minis, and Mac Pros are accepted provided they are from 2010 or later. In short, if your Mac runs Sierra today, then it can handle High Sierra because Apple has not restricted the list of compatible Macs. On the other hand, some functions are expected to be more selective. This is already the case in Sierra with Handoff, unlocking with Apple Watch, or the Universal Clipboard, which only work on newer Macs.

MacOS Sierra (10.12)

  • MacBook Pro (mid-2010 or newer)
