I cannot believe I did this, but indeed I did! I sold my iMac on eBay. Got almost enough to repay my savings for the cost of my new MacMini. BUT... When I wiped the iMac, I wrote down the new and generic password. Then, apparently instead of sending it with the computer, I misplaced it. The buyer just contacted me to tell me he needs the password. Help! There must be a way to get around it, right?
