I'm having some system problems on my macbook pro so I'm going to do an erase and clean install of Mountain Lion, and will want to be able to keep all my info and apps etc. It seems like the two different ways to do this are - Time Machine - make sure Time Machine is up to date, wipe the drive, install OSX and then do a restore with Time Machine. - Migration Assistant. How would this work with Migration Assistant? Do I use it to make a clone to another drive, and then use that clone to restore to my laptop drive? Also, anyone have a preference for one approach or the other? thanks!
