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.

Chiming in. I have had now 4 different MacBook Pro's and 1 MacBook Air and all of them have experienced similar problems, on three different ThunderBolt displays.


I have updated to the latest (v1.2) ThunderBolt Display firmware, as well as performed the annoying SMC and PRAM resets. I've also done the informal "Thunderbolt Display reset" which amount to un-assing all the connections and unplugging it from AC power for a minute then connecting it all back together.


Instead of simply the USB devices not working (no TimeMachine disk backup, no keyboard/mouse wake, etc.) which is often the case, or the display not coming up, I've additionally seen where the system will just freak and Reboot itself.


I have three displays, the TB display, a Dell ultrasharp connected via. DisaplayPort (using the second TB port on the MacBook), and another Dell ultrasharp connected via. the HDMI port. I've seen cases where the DP connected display comes up but the TB display does not.


Overall I'm really upset with this behaviour from a $1000 monitor, but I suppose we should all know better than to hope an "all in one" solution could be flawless. It's probably too much to ask for a dock/port-replicator AND display to carry over a single port and work right with performance. I'm leaning toward moving all my peripherals to a USB3 powered hub and just use the DP as a display-only.


I'll probably take my display into Apple to see what they can do with it though. Ugh.


Maybe the latest MB coming out with the AMD video card will fix all this instead of the nVidia card?

Yes, this is just one more in a series of spiralling deficiencies with my Apple products (all but the iPhone) - the TBD has been exhibiting this behavior since shortly after warranty on multiple machines. Same old routine, unplug, let cool, plugin - and sometimes to force it I plug it into a Retina macbook before plugging into my disappointing Mac Pro 2013 (as a 3D animator the dual D500 video cards are useless because Apple and AMD never update OpenCL). SO I am looking at bootcamp and the promising Windows 10... and a Dell monitor.
