How to Upgrade

Your Mac must be one of the fol­low­ing models:

• iMac (Mid 2007 or newer)
• Mac­Book (Late 2008 Alu­minum, or Early 2009 or newer)
• Mac­Book Pro (Mid/​Late 2007 or newer)
• Mac­Book Air (Late 2008 or newer)
• Mac mini (Early 2009 or newer)
• Mac Pro (Early 2008 or newer)
• Xserve (Early 2009)

Make sure you have Lion or the lat­est ver­sion of Snow Leopard.

While you have the About This Mac win­dow open, check what ver­sion of OS X your Mac is running.

If you are run­ning Lion (10.7.x), you’re ready to update to Moun­tain Lion. Go to Step 3. If you are run­ning Snow Leop­ard (10.6.x), update to the lat­est ver­sion of OS X Snow Leop­ard before you pur­chase OS X Moun­tain Lion from the Mac App Store. Click the Apple icon and choose Soft­ware Update to install Snow Leop­ard v10.6.8, the lat­est version.

Down­load OS X Moun­tain Lion from the Mac App Store.
