I have two TB displays(fw updated) and MBP 15inch Early 2011, osx 10.7.3 server

Dual TB displays can work.


I upgraded my osx from 10.7.3 to 10.7.4 yesterday, than my 2nd thunderbolt display cannot work.

I try to swap the position of the two TB displays and unplug/plug TB cables, got same problem, only the 1st TB display works normally.

anyone got same issue ?
