I've tried the combo update from the support page but I keep getting this:
Currently running 10.4. No updates available in the App Store.
Open > About this Mac > More Info, and tell me what you see next to "Software". I suspect you are using a pre-release version
It is a pre release.
OS X 10.8 (12A239)
You can only update to OS X 10.8.4 with the final version. Buy OS X Mountain Lion at the Mac App Store
Not the answer I wanted but it is the answer. Thanks.
You are welcome
