If you plan to install Mountain Lion on an older Mac, you might be out of luck. The new operating system release raises the ladder in terms of graphics performance required for its new features like AirPlay Mirroring. As a result, a couple years old Mac might not cut it anymore. According to French-language website MacGeneration, any Mac sporting Intel’s sluggish GMA x3100 or 950 chip will not be able to run Mountain Lion. While we have come a long way since the GMA graphics, you probably have somewhere under your table or in the basement a legacy Mac that does not have enough oomph for Mountain Lion. Anything older than the mid-2007 iMacs, early-2008 Mac Pros, early-2009 Mac minis and Xserves are left behind. The same goes for MacBooks based on any Intel Core 2 Duo processor and the original 2008 MacBook Air. Sorry folks, that is the price of progression.
