The display works perfectly up until the point the computer is shut down or put in to sleep mode.
After this when the computer is turned back on again the USB / Sound / Network functions don't work, I have to unplug the monitor and plug it back in.
I have the latest firmware so not sure how to fix.
This has been nagging problem for some time with my set up as well (Thuderbolt display and a macbook air 2011.) The latest firmware update seems to have alleviated the problem - now when there is no sound from the Thunderbolt display, I just disconnect it from the MacbookAir for about 5-10 seconds, and then reconnect (while the Macbookair remains awake the whole time). The sound seems to come back usally at that point...
Hi,
I agree that if you disconnect / reconnect the monitor or unplug and plug the monitor back in you may be able to get these features back but this is not an acceptable solution for me.
The display should work all the time, I thought that was what Apple prided themselves upon.
I have a similar problem.
I have a brand new TB display with a brand new Retina MBP.
USB KB via TB display is occasionally inop after wakeup from sleep.
I'm having a similar problem, only worse... When waking from sleep, the MBPr no longer sees the USB HDs. The only way I can get it to recognize them again is to reboot. I wrote Apple but got no response.
If anyone has a solution, please let us know.
I'm also having the same problem. Macbook Air with 27" thunderbolt display. When will apple address this issue, or does this list need to grow to thousands of people complaining?
Similar issues here.. was working fine on Retina MBP.. then with the latest EFI update I fear the Sound is not longer ported via the display and it wont wake from sleep sometimes with monitor connected.
Additional info.. this issue only seems to have happend after the last Mac OS update and EFI firmware update so I am hoping its linked to that and can be fixed... asap.
This problem went away after a few weeks, perhaps I got an update I didn't notice.
I now have the same issue with TBD and rMBP. After applying the EFI and 10.8.2 OS X update, my rMBP will not wake from sleep with the USB keyboard connected via TBD. I have no issues with sound or external HDDs though.
My workaround for now is to connect the USB keyboard directly to the rMBP USB port and I can wake from sleep. I've called Applecare today and finally they had me send a log of my system so their engineers can look at it. Should hear back from them in a few days.
For now, I recommend connecting your keyboard directly to the rMBP instead of TBD to wake from sleep.
Will update once I hear back from the Applecare folks.
I have been facing similar problem myself. I recently reinstalled mountain lion because my rMBP was giving me some troubles. Now since last night my Thunderbolt Display sound keeps going away. If I reconnect the display the sound remains for like a minute and then again gone. Although this issue wasn't there when I plugged the display into my sisters MBP 13. This makes me wonder if I got a crappy rMBP but series of questions here tells me otherwise. Restarting does help but in my case for only a few minutes or so.
Unfortunatly I have to join. It started with not waking up any more. Now, sound, camera and mic are also gone.... 😟
The 10.8.2 supplement 2.0 fixed my wake from sleep thunderbolt display issue. Now my rMBP wakes from sleep with the wired keyboard attached to the display. Looks like Apple fixed it.
I have made the upgrade with the 10.8.2 suppement 2.0 and there is no change...
Grrr...
I have two thunderbolt display one at work and the second at home.
It's a shame for the price.
The problem come with the last update...
Thunderbolt display loses sound/usb/network after computer sleep / turn off
