I bought a new macbook pro 13" a month ago, I went down to Compusa and bought some centon memory power pc3-8500 ddr3 1066 two sticks of 4gb. Installed them and my pro went dead, it did not boot up, just a blank screen. I tried it in my mac mini as well seeing as they use the same ram. No dice, dead as well. I searched online and I read that apple products are a bit picky about what you put in them. I just want to ask the forum members here if this has been their experience as well. I'm going to go down to the store and return the ram and i'm wanting to know if I should change it out for something different and if so what brand do you all recommend. I went ahead and installed the original ram and pro kicks on like all is well.
