said by skeechan:Macs are very RAM picky so many sure that the store has a good return policy.
That might've been true in the PowerPC days, but the Intel Macs are much more forgiving in my experience. Every stick of RAM I've thrown in a Mac (probably close to 100 sticks) has worked so far.
For my personal Macs, I typically buy the cheapest RAM on newegg (which is usually G.Skill) and haven't had a problem yet.
