Factory reset/wipe new iMac (2013)
I need to wipe my new iMac and all data, including passwords, ID's etc. But how? I'm giving it to someone and need to ensure everything is clear and not recoverable.
As there is no CD drive, I do have an external CD drive.
Software = OS X 10.8.3 (12D78)
iMac, OS X Mountain Lion (10.8.3)
