In our household, we have 4 iPhones/iPods and 3 MacBooks. On the iOS devices, if I buy a game from the App Store, it can then be downloaded for free onto each of the other iOS devices (since we all use the same account). Does it work the same way for the Mac App Store? For example, if I buy Lego Star Wars on my MacBook Air, can my daughter also install it for free onto her MacBook (since it also uses the same Apple account)? Thanks!
