Alright so I obtained a new set of keys at approx 3 am (eastern time USA) today and im assuming they will work and not have the prior "keys have already been used" issue. I'm new to mac os (MBP13 is 3 days old) so i'm not sure HOW or IF i should do a clean install of ML? Exactly how do you even install ML? Please help us noobies out! Ive been reading stuff about creating partitions, using backup programs, or using the built in "download and install" procedure but i'm stumped on what to do or even how to do it. Provide detailed or simplified instructions on how to wipe my HDD/OS to install ML or if it's even necessary? Thanks!
