Corsair Mac Memory Upgrade Kits: Guaranteed Performance, Compatibility, and Support.
Corsair's 4GB and 8GB Mac memory upgrade kits will help your system work better. With hassle-free compatibility and renowned Corsair reliability and support, they're a smart performance investment.

One of the best ways to improve your Mac's performance
Applications use memory, and some of the applications that run best on the Mac — photo and 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 and 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, and more time working — or playing. Upgrading memory can also be a cost-effective way to get more life out of your older system: before you trade up to a new one, just upgrade the memory.

Tested at Apple Developer Compatibility Labs for Guaranteed Performance
Corsair's Mac memory kits are guaranteed to work with any Mac desktop or laptop that supports 4GB DDR3 SODIMMs, including iMac, Mac mini, MacBook, and MacBook Pro models. This includes virtually all models offered by Apple since 2009.
