Wiping An Apple Mac For Resale I don't use my Mac so I'm going to sell it. I want to give the customer a clean Mac, so I have completely wiped the HD and reinstalled Mac OS X. I've been reading about people getting locked out of their second-hand Mac and it being still linked to the previous owner's account. I wanted to know if this is the case because I want them to be happy with it and be able to use it when they get it. I logged out of iTunes and iCloud and turned off Find My Mac, then I did the full wipe and reinstall. Now I'm up to selecting the language and stuff. Is this enough? I want it to be new and without an account but watching a video when they went back onto the Mac they had to log into their account again.

Should I complete the setup and see or will I be fine leaving it?

Thanks.
If you've erased the drive, you're most of the way there. It really depends on what you want the experience for the buyer to be. I would print out this web page and check mark what you did so the buyer's mind and yours are both at ease:

The last step (6 of 6) reads:


  After you reformat your hard drive and reinstall OS X, the computer restarts to a Welcome screen and asks you to choose a country or region. If you want to leave the Mac in an out-of-box state, don't continue with the setup of your system. Instead, press Command-Q to shut down the Mac. When the new owner turns on the Mac, the Setup Assistant will guide them through the setup process.


If your Mac doesn't come with Internet Recovery, you might consider making a USB drive for them to install the version of OS you want to ship. They can always call AppleCare and arrange for replacement media or a download code to redeem the version of OS that shipped with the Mac in question. Most recent hardware works with Internet Recovery and most older hardware has physical install media you can/should ship with the hardware or that could be ordered for nominal cost from Apple.
