Factory Reset without Admin Password, MACbook Air
I have a Macbook air 10.9.4
I want to reset it to the factory settings. I do not know the admin password though. I tried doing to holding down command and R thing, but all that happened was a grey screen came up with a picture of a lock, and a block for a password to be entered in, but I don't have a password.... Please Help!!
