If you don’t intend to keep or use your other computer, it’s best to deauthorize it from playing music, videos, or audiobooks that you’ve purchased from the iTunes Store. Deauthorizing a computer prevents any songs, videos, or audiobooks you’ve purchased from being played by someone else, and frees up another authorization for use. For information about deauthorizing, choose iTunes Help from the Help menu in iTunes.
After you set up your Mac mini, check for updated software. Choose Apple () > Software Update from the menu bar and follow the onscreen instructions.
