That should do it, as all of that data you are worried about would be in the files contained inside the user account. You'd do that anyway before taking it in for service.

And backup before you turn on File Vault too, just to be safe.

If not, it may take some time to encrypt the real account, so let it run overnight at least. If you already do that, then you are set. So you would need to use File Vault on the real account. Let them have access only to that new empty admin account.īut they could still access the drive directly and grab files from the real account. But you do that already, right? Then create a new admin account that has nothing in it. But that is a huge amount of work with lots of potential for problems to arise.ĭefinitely set your account with a password. But that is difficult, so then maybe backing up and cloning the drive (no less than 2 copies then) and then wiping it. Probably the only way to keep your data completely safe would be to remove the hard drive.
