    Hi,

    Was thinking about upgrading my wife's macbook from Snow Leopard to Mountain Lion.

    Would this be equivalent to a clean install:

    1. Backup her Snow Leopard to Time Machine (just as a precaution)
    2. Upgrade Snow Leopard to Mountain Lion (not a clean install)
    3. Do a new backup of the upgraded Mountain Lion to another Time Machine
    4. Format disk, clean install Mountain Lion
    5. Restore Mountain Lion from Time Machine (to get apps, settings, etc.)

    What I'm trying to do is avoid having to manually reinstall documents, applications, etc. I don't mind if this process takes a little longer as long as its automated and I don't have to sit there and babysit it.

    Sorry if this is a totally idiotic idea, I tried to search here and via google and didn't come across it. Thanks.

    No, thats not a clean install. you may as well just upgrade after the first time machine backup. if you do a full restore from time machine it wipes the drive before restoring.

    A clean install would be to backup your documents, do a fresh install and then restore only the documents and reinstall all the apps from their installers / CD's etc.
