Hello,
Seems that somehow my son updated his white MacBook from OS X 10.7 to 10.8.3. Now the machine will not boot.
I've reset the PRAM and repaired disc permissions and tried to reinstall OS X.
When trying to reinstall OS X, the system tries to install 10.7 but then refuses to continue because it sees that the more recent 10.8.3 is installed.
Anybody have a quick fix for this?
I know that I can erase the drive and reinstall fresh, but I am hoping to avoid that.
Thanks much in advance!
