I purchased my Macbook Pro along with a 500gb TC yesterday. I do not have internet connection in my home at this time but I would like to use the TC to wirelessly backup my Mac. I have set up time machine and when I select the TC for a back up it wants a password. I have no idea what that password is so I go to airport utilities. I try setting it up though there. I change the password but when the TC restarts the Mac cant find it. I'm away from my home now and hoping I can get a quick answer or I'll just call the store when I get home. Please help!
