I searches and only came up with retina 15" problems... My 2012 base model mbp with upgraded 16gigs of ram has started hanging up lately. It's intermittent (or was until it did it many times today) but while doing menial tasks will freeze for a few seconds. It was most noticeable when playing music in itunes, the music would stop, then resume a few seconds later. I get the beach ball when this happens and then it usually resumes. I normally use google chrome and it hasn't given me problems until this week. I upgraded to ML a couple weeks ago because it was free. It was working fine until this started. I've used disk utility to check the disk, and repair permissions. I've reset the, can't think of it, (hold ctrl, option, command) when it's off. Nothing works... And it's getting worse. Now for the worst part, we just moved to Germany (my wife is an army Dr) and our house doesn't have regular internet. I've been using a surf stick which is painfully slow anyways. Not sure if I can download and reinstall ML... Suggestions?
