    Hello Everyone!

    Have Mountain Lion DP3 installed. No problems. Very polished OS at this stage.

    Can I simply install future DP through final releases of Mountain Lion on top of what I have already or am I going to be forced to downgrade to Snow Leopard first?

    Thanks in advance

    You cannot install release versions of MacOS X over developmental versions.

    For Lion this was not an issue. You simply redeem your GM code in the app store and install it. You were able to install over a DP without an problem.

    Okay, so the final version can be installed over the DP.

    That is what I was hoping to hear.

    Thank You

    So, if I don't have a GM code, and I was to purchase Mountain Lion from the App Store, would it still install over DP3 or not?
    Thanks :cool:
