#PREPARE MAC MINI FOR RESALE INSTALL#
Other companies may also track which machine their software is installed on and will not allow you to install that software on a new machine without first deauthorizing the old one. It’s easier to just deauthorize in advance, by opening iTunes and choosing Deauthorize This Computer from the Store menu. However, you can only do this once per year. (In the case of iTunes, you can deauthorize all devices, without having access to all of them, then re-authorize the ones you still own. Before selling, you will want to deauthorize the computer.

If you have purchased music or movies from the iTunes Store, you can play them only on machines that have been authorized by your account. The first thing you need to do, as the seller, is deauthorize the computer from any systems that only allow you to use a certain number of machines and track which ones you are using. (As the seller, you may not be terribly concerned about the buyer’s feelings, but keep in mind that the price you get when selling on sites like eBay can depend on how satisfied previous buyers were with you as a seller.) With just a little work, you can clean the machine up, preventing all of these issues, prior to sale. Proper security is important to both parties. Unfortunately for the buyers, this is often done improperly, leaving the buyer with a junk computer that isn’t working properly… sometimes even containing malware! For the seller, such improper preparation is a danger as well, as the buyer may be able to access sensitive data left unknowingly on the machine. People sell their computers all the time.
