Q: Thunderbolt display will not work on my MacBook Pro Retina after Mountain Lion update?
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!

SOLVED
The fix involves deleting 2 preferance files in the Library.
1) Macintosh HD - Library - Preferances
DELETE:
com.apple.windowsserver.plist
2) Finder - Go - Option - Library - Preferances - By Host
DELETE:
com.apple.windowsserverxxxx.plist
3)
Then, peform a PRAM reset.
Problem solved.
Apple has advised that a software update will be out in a few days. Otherwsie, the above works perfectly!
Wooo hooo! Love you, Apple!
PS:
If you are not comfortable performing the above, please contact Apple Support, and ask for Level 2 support. They will gladly walk you through the process. Alternatively, just wait for the software update.
