How do I reset to factory a MacBook Air mid 2011 that I bought from a friend??
Hi I was wondering if someone could help me..I just bought a MacBook Air mid 2011 model and it's running on the current maverick software.
The thing is, when I click on user accounts it still shows my friends name, there are a couple of other occurrences of this too.
I have already tried reinstalling mavericks but it didn't remove this info, i would really like to factory reset it if possible...
Help would be gratefully appreciated (am new to mac)
Many thanks in advance
Ian
MacBook Air, OS X Mavericks (10.9.1)
