    Hi,

    Can someone tell me the best way to update DP4 to GM?

    I've got the GM downloading from the app store but have never updated a pre-release copy of OSX.

    Cheers

    Just download and install. I just upgraded from DP4 to GM 4 hours ago without any issues, so far.

    Is Apple's upgrade process basically the old 'archive and install' method, or do they only update key components of the OS?

    Trying to decide whether I want to update from DP4 or do a clean install.

    Try repairing Disk Permissions.
    Then restart.
    And then mount the image.
    Show Package Contents.
    Mount InstallESD and run the installer from there.

    Cheers.
