Newbie question: As I understand it I can upgrade up to five computers from my ID. I bought a new iMac a few months ago with Lion. I'll pay for the upgrade, but can I upgrade my daughter's Mac Book Pro that's on Snow Leopard straight to Mountain Lion? Or must I upgrade to Lion first? Thanks in advance.
There aren't any limits for apps including OS X. That 5-computer authorization process is for music at iTunes. Nothing to do with MAS.
