hello, selling my first mac to buy one of the new pros that just came out. i want to wipe everything off of the mac but keep all of the apps that are currently on it. what would be the best way to go about this?
Create a new admin account and log into that. Then delete your old account via System Preferences and then the Home folder via Finder.
Then open Disk Utility and choose ERASE FREE SPACE under the ERASE tab.
ZERO OUT should suffice and will make your deleted data un-recoverable.
