I have a dilemma. I have posted on another thread previously, but now I have a new question about Apple ram. http://forums.macrumors.com/showthread.php?p=5053960 To summarize my problem, I am having issues with a brand new Leopard install on my MacBook Pro. Immediately after a fresh install, when I try to access the Applications folder, Finder crashes, and re-launches itself. I have reinstalled Leopard I believe a total of 6 times now. Every time it's the same issue, except for the one instance when I installed with only the original 2gb Apple ram in my MBP. All other times, I had 3 gb total, with a OWC 2gb stick and one 1gb Apple ram stick. After calling OWC, they suggested ram tests, so I installed the OWC 2gb stick in the bottom slot and the test showed it passed (I did 10 tests) The tech at OWC had also mentioned that Apple might only like apple ram when installing Leopard, so maybe I should install Leopard using the original ram, and then add in the OWC 3rd party ram later. Does this make sense? After looking at some prior posts on this forum, so many believe that ram is ram is ram. Could Apple ram be "different" ? And could the 3rd party ram be 100% okay except for installing Leopard?? Or maybe I should complete the rember tests using each stick separately, including the Apple ram??? I am really confused, and I hope someone might help. Thank you so much!!
