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!
Any ideas?
For anyone interested, the engineering department at Apple is looking into this issue. Once they determine a fix, I will post back with what they will have told me.
Thanks!
The new 10.8.2 "Supplemental Update" does not fix this issue!
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.
You, my kind sir, are a life saver. Can't believe it's almost December though with no update fix though.
My issue wasn't with Thunderbolt however, it was with the insanely low FPS in games.
Thunderbolt display will not work on my MacBook Pro Retina after Mountain Lion update?
