I am also experiencing crashes upon trying to open a game on my rMBP (10.8.2). It also won't detect my wii remote even when its synced with os x (or even when its not synced with os x). Not sure if its the same problem or not just thought i'd say it. Im using a self-compiled version of 3.5-134.
Checkout my latest project ( it is a program that downloads and compiles dolphin on mac and linux now): http://code.google.com/p/dolphin-emu-downloader (It's unofficial and maintained by me, not the dolphin dev team)
