Major problems with Thunderbolt display & MB Air

Since I received my Thunderbolt display yesterday and hooked it up to my 2011 MB Air, I've had nothing but problems.


Software update is fully up to date, including the TB Display firmware.


I'm experiencing three major issues:

1. About half the time when I connect the display, my connected USB devices are non-functional. Unplugging and reconnecting the devices does not fix it.

2. Also, about half the time when I disconnect the display, the MB Air does not reconfigure the monitor layout. Putting it to sleep and/or disconnecting / reconnecting monitors does not fix this. I have to hard restart my laptop.

3. When connected through the TB Display, my Mac will infrequently not recognize key up events from my USB keyboard, causing keys to repeat until I hit them again. For an idea of frequency, it has happened 4 times so far thus far while writing this post.


Also a couple of minor niggles:

1. The default color calibration is WAY different from the MB Air's screen. It's most obvious with yellows which have a severe green tint on the TB display. For example, note windows in Mail appear very slightly orange on my MB Air (as expected given the color value), while on the TB display it is florescent yellow with a slight greenish tint.

2. The sound is a lot poorer than I had hoped. I wasn't expecting anything really amazing, but with the "built in subwoofer" I expected noticeably better bass than my MB Air's built in speakers provide.


The minor issues can either be minimized (with color calibration and equalizer) or ignored, but the major issues make this display completely unusable for me. Is this just a defective unit, or are these widespread issues?


Thanks in advance for any help.


PS. Total instances of keys getting stuck while writing this post: ~9. Seems to only be space and delete that get stuck so far.

MacBook Air, Mac OS X (10.7.1)

Pretty crazy...you would think Apple would have tested theses display with Apple wired keyboards. It will be interesting to find out if an exchange worked for anyone.

The keyboards have firmware too so maybe there will be an update for the keyboard to fix this. These displays are so perfect for Air users that I would rather buy a wireless keyboard than not have the display.

Resetting the MacBook Air's SMC solved the keyboard issues. My mouse still quits working spontaneously a couple times a day, requiring me to unplug and reconnect the USB receiver. This is only a problem when the receiver is plugged into a USB port on the Thunderbolt Display or on the wired keyboard connected to it -- not when connected to a USB port on the MacBook Air itself.

I have a MBP 2011 17inch with all patches applied. Thunderbolt display with all firmware updates.


The display works great untill I disconnect the Thunderbolt Cable and do some work in the field. I come back and reconnect the thunderbolt cable.


Display works, ethernet works, Firewire works.


USB does not work (no keryboard). Camera does not work, Sound Does not work, Microphone does not work.


I have to reboot the macbook to get the USB and all the rest working again.


Talked to AppleCare, I am sure they have never seen or touched a Thunderbolt display @ this time.

Adding my voice to the chorus. I have a new 13" MBP and Thunderbolt Display. I'm seeing dropped keystrokes on my USB keyboard (MS Natural Ergonomic Keyboard 4000) connected via the Thunderbolt Display. These symptoms did not exist before I got my TB display.


Did all firmware updates and SMC reset. No real help. It may have reduced the frequency of dropped keystrokes, but I haven't actually been able to tie down what a regular frequency is, since it would flair up and be horrible at times, and other times be quite rare and sporadic.

The USB drops are starting to drive me crazy. My wireless Kensington mouse just quits working multiple times a day, requiring me to disconnect and reconnect the receiver. Then it'll work again for a while, though sometimes I get several drops in a row. I've tried zapping PRAM, resetting the SMC, and all Thunderbolt-related updates have been applied.


The USB in the Thunderbolt Display is just screwed up somehow. I hope this can be fixed in software.

As I've mentioned, I have an external harddrive that is plugged into the back of the TD which loses power, similar to the keyboard issue (which i also have). I'm wondering if anyone else who has a device plugged into the back can actually tell if the device is getting power when its plugged in?


What I have found is that when the harddrive is plugged into the TD AND the thunderbolt cable is plugged into the Macbook Air, the harddrive gets no power...but, when I unplug the thunderbold cable from the macbook air, the harddrive once again gets power. (the power is obviously coming from the display, but since the thunderbolt cable is disconnected from the computer, its not recognized)


Wondering if anyone else has had a similar issue?

Sep 28, 2011 12:24 PM in response to bazaarone

Same issues as everyone else here with dropped keystrokes when keyboard/mouse plugged into the Thunderbolt Display. I wonder if the keys are dropped during high ethernet demands and even the uber-fast Thunderbolt connection can't keep up with the data so keystrokes/mouse clicks are missed?


UPDATE: Nevermind, I just unplugged the ethernet cable so there should be minimal communication demand and I still had the same issues.

I wanted to give you folks an update on this. I received an Thunderbolt Display firmware udpate today Verision 1.0.


Now all the troubles with USB, sound, camera, microphone are gone.


I have a firewire drive plugged into the TD and it works fine (but it is a LaCIE 2TB drive so it has it's own power adapter, if that could make a difference).


Just a positive update.


thx
