this is probably the stupidest question ever but i'm on my dad's mac and it's in windows mode, and i've never used parallels before and i haven't got a clue how to get it to go back to mac. i've been trying for like an hour but to no avail, enlighten me? cheers
Alt + Enter. If that doesn't work, you're running Boot Camp, in that case select the Boot Camp tray icon on the bottom right of your screen and then select to boot to OS X.
