What happens when you format the main internal hard drive to MS-DOS?
Just totally out of the blue question, although I'd like to install my OS again (probably not in MS-DOS format, would that be possible though?). It feels like I own the machine more when I set ALL of the stuff myself. Would that force me to download OS X El Capitan from some hidden partition or something?
Thanks in advance.
MacBook Pro with Retina display, OS X El Capitan (10.11)
