I have a friend who recently bought an iMac which I guess was older stock - it still had Snow Leopard. Sure, he gets a free upgrade but it requires an Apple ID. An Apple ID requires a credit card (lame!). He doesn't own a credit card. Taking it back isn't an option. So how does one upgrade without a credit card? He's pretty mad that he needs one for a "free" upgrade. Any advice would be appreciated. Thanks!
