One of the best ways to improve your Mac's performance Applications use memory, & some of the applications that run best on the Mac — photo & video editing — use lots of it. That's why outfitting your Mac with a Corcair Mac Memory upgrade kit is one of the best things you can do to maximize your system's performance & agility. With a Mac that's been upgraded to the maximum amount of memory it supports, you'll spend less time waiting for your applications to buffer data to the hard drive, & more time working — or playing.
