System requirements for OS X Mountain Lion

// February 12, 2021

Apple is going to release OS X 10.8 Mountain Lion this summer to the public. The updates to the operating system will continue to bring iOS features back to the Mac. One of the most notable features is AirPlay Mirroring, which will mirror the display from a Mac to an HDTV via Apple TV. What Apple hasn’t mentioned yet is that some older Macs won’t be able to support AirPlay Mirroring and possibly some of the other new features with OS X Mountain Lion.

You may be wondering if your Mac will be compatible with the new operating system. Here is a list compiled from the developers preview which was released today.
