I recently purchased a new computer for my parents' home. It's a Mac Mini running Lion and I've transferred all the files/settings from their previous Mac (and old G4 running OX10.4 I believe). Anyway, I'd finally like to setup different user accounts on this new system, but want to make sure I understand how it all works first. On top of the two separate accounts for my parents, I'd like to setup a third one for my cousin who lives with them. So my understanding is that if I want them all the have their own accounts with their own Home folder and Documents folder, etc., that they will also have their own copies of each application they use. Is this correct? It seems needlessly redundant. If my mom purchases Pages and Numbers in her account and installs it, does it have to be installed in the other user accounts separately and does each install require a license? I think that's my main concern right now.
