Thats odd, and an issue I’ve never heard before. I work for an apple premium reseller, we’re not technicians but we do this all the time and havent had any problems that I can think of- just make sure you get the right knd of ram (I believe it’ll be 1066mhz) and you should be fine. Also I would advise not going for the cheapest you can find, faulty ram can cause things like kernel panics; we sell Kingston, which is very good stuff. Installing it is a cinch, depends on which model you have but the worst youll have to do is unscrew a few screws and literally cram the stuff in there haha. People recommend you ground yourself first though, so you are not statically charged, but again, this is not something we worry too much about and I’ve personally never had issues, even after doing it to hundreds of macs.
