I have written to find out if anyone has experienced this issue of their Thunderbolt display not working after upgrading to Mountain Lion on their MacBook Pro, with retina display.


Both screens go black. A large mouse pointer appeas, but that is it.


I have tried applying the combo update to see if it would correct things, to no avail.


Does anyone have any thoughts or advice?


Thank you!
