I just want to do a clean install. I have backed up my entire Lion system using Time Machine to an external drive. Can I do a clean install of ML without doing any voodoo with bootable USB drives and such? I've got my system backed up, so if anything goes wrong, could I revert from my TM backup?
I know this is really basic, but I'm new to this aspect of the mac (just got my external, just setup Time Machine).
The reason I want to do a clean install is because when I setup my 2012 MBP, I imported everything from my 2009 iMac. Then I did a clean install of SL on my iMac to set it up 'as new' for someone else. Right away, I was amazed at how snappy the system was.
I have slowly become accustomed to delays, beach balling, and lag on my iMac. I see some inexplicable behavior on my 2012 MBP, and think it's because of the settings and crap I brought over from my messy iMac. Want to do a clean ML install to see just what this computer can do!
