I have two 27" Thunderbolt Displays (daisy-chained) plugged into a 15" MBP. The problem is, seemingly at random, the monitor's switch arrangement, the left being primary one day, the right another day. I haven't been able to find any sort of pattern in the switching.


Also, if it helps clarity the problem, my MBP is always closed when I plug in the monitors.


Is this a bug? Any workarounds?
