Hello, My roommate has an Ipod touch. A friend of hers formatted it on a pc and now when my roommate plugs it into her mac it doesn't see it. I plugged it into my pc (vista 64) and it saw the device right away as an ipod touch. Not sure what to do for troubleshooting. Once it gets formatted on a pc is there something that has to be done to get it to work on a mac again? I dont have Itunes on my pc, will I have to download it to fix this? Thanks for any suggestions if you need more info let me know!
