Want to reformat my Mac Mini so I can resell it. Is CMD-R enough?

    I want to reformat my Mac Mini back to its factory fresh state. I did the CMD-R on bootup, and selected to reinstall Mountain Lion via internet connection. The install goes smoothly and now it is asking me to create an account. I'd rather not do that and just let the new owner do it, but I was wondering if there was anything I missed? My mini came with a 500gb platter drive, and I ran OSX off of an external USB 3.0 SSD drive. So the only thing on the platter drive would have been some music and movies. Nothing that I'm worried about getting into the wrong hands.

    If that's the screen it's at, then you're ready to sell it.

    Should be enough. Unless you sell it to someone who decides they want to dig into that drive and find files that weren't quite erased, you'll be okay.

    When you booted into the recovery, did you launch Disk Utility and format the drive before reinstalling? If you didn't then any files that were there before would still be there.

    No I didn't. It's not a big deal, but I guess I'll reformat the drive anyways.

    boot with your external ssd. call up disk utility. then erase with secure option 7 pass. on the second pass exit the job. then format then do a cmd -r.

    writing the disk with 1 full pass of zeros is pretty much impossible to find old data.

    takes a while 2 do = 2 hours if your drive was a 500gb 4 hours if it was a 1tb
