Sorry if this has been asked a million times. I've tried searching but am not having any luck. I just installed 10.10 on my MBP 7,1 without issue. However I would like to run a current and supported version. I downloaded the latest (13.04) and burned the image. When I tried to boot from the disc I get a really glitchy page that is unreadable. After some research it looks like my MBP is not supported on that release. So I ask, what is the most current version I can run?
