Does anyone know how to use iTunes Match for two separate users on one Mac? My husband and I each have a user account on our iMac. Our iTunes libraries are completely separate (wildly different musical tastes). We each have one iPhone 4S and one iPad 2. Our iOS devices are tied to our own Apple IDs. The iMac is the only thing we share. He set up his match first. Everything went fine. I went to set up my match, and it tells me that "This device is already associated with an Apple ID." It freaking asks me if I still want to pay my 25 bucks knowing that I won't be able to use the service!!! What?!?! If this isn't just some bug and is really how the service is intended to operate it is completely unacceptable. You can't really tell me that I either have to get another Mac or I'm out of luck. I would appreciate any and all ideas.
