Want to sell old iMac. It has been backed up, de-authorized with iTunes, and wiped with the 35-pass erase. Now I want to reinstall OS X but no longer have an internet cable as we have gone from TWC to the ATT 'fiber optics' system since the old Mac was erased. Please help.
iPhone 4, iOS 6.0.1
Even though you have AT&T fiber optic to your house you would still have a modem or gateway where you can connect an ethernet cable to your iMac. See the following link for photos of one example, although your model may vary: https://fcc.samknows.com/install/att/uverse
Be sure to follow Apple's instructions in this document: What to do before selling or giving away your Mac - Apple Support. If you don't you can create a problem for the buyer and yourself down the line.
