    Fast question. I'm on Mountain Lion. If I upgrade using the Mac App Store way would I lose all my already installed apps and documents?

    Thanks.

    Nope - but....always do a backup before upgrading.

    You won't lose anything, but you should still back up your most important files to an external source.

    My Time Machine Archive went south when I updated, inaccessible.
    That's not a common problem, but it can happen.
    I'm glad I made a full backup to a non Time machine partition as well.
