MobileMe hosed my Mac
Yeah, Macs don't crash. Macs are easy, you don't need to worry. System updates are reliable. Yesterday my Mac Mini's software update prompted me to install the system upgrade that would add MobileMe support. So routinely I clicked yes. This morning when I booted the Mac I was greeted after login with "The application FileSyncAgent quit unexpectedly." and very ironic below "Mac OS X and other applications are not affected".
Bah humbug! The crashing file sync agent takes down the top menu, so I even can't access the preferences to switch off Sync. Also opening Finder or any application wouldn't work. So basically the Mac is dead. I guess the Mac of SWMBO will not get that upgrade any time soon.
Update: I reinstalled the Mac, but I mixed up the install DVDs. It is now happily running on OpenSuse 11.0.
