Hi, I have a MacBook and am going to buy an iMac soon. In our household we have three different iPhones each with their own iTunes account. Each member of our household with have their own user account on the iMac. I want to set up each iPhone to wifi sync back to my new iMac. I understand that I will have to sleep the iMac, automatically wake it up and leave iTunes open, but doing a little test on my Macbook I noticed it wakes up into a user account. Does this mean it will only wifi sync that particular user? Is there any workaround so all users can wifi sync? Thanks.
