I’ve had some luck so far with MobileMe, but this time I ran into a complete fail. It wasn’t completely unexpected.
I’ve been using LogMeIn to do remote maintenance of my mother’s Mac Mini, often using my old XP machine. It connects at the machine level; I can log out of her account and connect to the admin account in one session. Today performance using the Firefox plugin was excellent.
MobileMe’s Back to My Mac works very differently. It connects at the account level, and it’s designed as it’s named – to connect between two OS X machine-user-accounts that share the same MobileMe name. In other words, to connect to one’s own account – at the machine level, not the account level.
I had to setup an account on one of my machines with the same MobileMe user name as my mother. Then I could try the connection. As promised it did show her machine in my Shared device Finder display, but when I tried to connect I got a “connection failed” message. I assume my mother’s cable modem/router configuration is not supported.
Even if it had worked though I wouldn’t have been able to switch to her Administrator account, B2MM is an account level connection only.
OS X remote maintenance is certainly unimpressive. I’m even more impressed now with LogMeIn. This MobileMe feature failed.
