Hi Charles, Take a look at Ramseeker.com. As long as all the specs match up, it should work fine. It doesn't need to come from Apple. However, some Macs require higher toleranced RAM to operate properly, so make sure it's the right flavor. Depending on your Mac and the RAM, poorly specced RAM can cause no problems, flaky and erratic performance, or total inability to boot. Problems should resolve when you remove the inappropriate RAM. Lower speed RAM will work, but will degrade the performance of any/all higher speed RAM. This is likely trivial for most users.

And to my knowledge, there is always non-Apple RAM that will work just fine with any given Mac. Apple recommends certain RAM because they *know* it works well. I say get what you want and enjoy, because I've always put off-brand RAM into my Macs and I doubt it's caused me any problems.
