I have an Air and a Mini. The Air has my iCloud account on it and the Mini has my wife's iCloud on it so that her Photostream has somewhere to be saved. I tried to set up Back To My Mac on the Mini so I could get to it from the Air when I'm at work but it's not showing up in Finder. I added both of our iCloud accounts in the BTMM section of our Time Capsule. Is it possible for me to get to the Mini even though it is signed in with her iCloud account?
