OK, I haven't bought anything through the Mac App Store except for Lion, which I did last month. Now my question is: while I have the app store open on my iMac, if I click the little price icon, and then I click buy app, will it just start downloading automatically or will it ask for my password. I am logged in with my Apple account, as when I click the Store menu you can see my account info next to view my account. Speaking of which, if I select view my account it does prompt me for a password, and gives me the option to sign out. I'm just curious, not that anyone has access to my computer, but I'm just wondering how easy it is to buy apps.
