Frequently Asked Questions

Can I run Mountain Lion on a PowerPC Mac (e.g., PowerBook, iBook)?

No, Lion can only run on Intel chips with at least a Core 2 Duo. If you are using a white/black MacBook or the aluminum MacBook/MacBook Pro, you can install Mountain Lion, given you have at least 2 GB of RAM. It would be recommended to have at least 4 GB of RAM, however.

Is there anything I should do before installing OS X Mountain Lion?

Always backup your hard drive before you install software on your computer. We suggest that you also do the following to ensure the operating system installs correctly:

  • Updating any software on your computer by going to the software's website
