I'm trying to reinstall OSX, but it won't let me 'cause it says there is a newer version already there. This is before I get to the "erase and install" option.
How can I get around this?
OK, here's where I'm at-
I can't click options because the button is not enabled.
I see nothing that says customize
I can't click erase and install because that button is on the next window which I can't get to.
Disc utility will not let me erase the disc. Buttons are not enabled.
Installer only shows one option as to where to install, MacintoshHD.
I can't install on MacintoshHD because "a newer version already exists" there.
I can't erase MacintoshHD because....return to top and repeat.
