I hit a wall yesterday with my MacBook Pro.
Time Machine is just utterly broken on my MacBook Pro running Yosemite. Just going to use this black MacBook from now on, I think.

(My tweeting went downhill from there.)
In short, Time Machine would start, but get stuck after just a few moments. Sometimes, it would stall on Preparing Backup… and other times, it’d get a couple of hundred megabytes done (out of several gigabytes it needed to do) then stop.
