Rating: 5/5 As Advertised June 9, 2015 I was running my 2009 Mac Pro with the stock 3GB of RAM since I got it back in 2009 with no problems. Fast forward to late 2014 after begrudgingly updating my OSX to 10.8 from 10.6 (some of the newer software/programs I use for work isn't compatible with with 10.6) my Mac started running slow because of all the memory the newer software/programs required. I pop in 24GB RAM and my Mac is running like a new again. 6 months into installing the RAM I haven't had any problems.

I would recommend this item to a friend!
