Dumbass, I know- how do I install 10.8.2, currently using 10.7.4? Multi-stage process, I assume, or can it be done in one hit?
About to download, noticed "Requirements- OS X 10.6."
Sole reason to upgrade is that I can't make a boot disc as I missed that on Lion install. Presumably will be able to with 10.8.2 ?
