    Hi There

    Is anyone running the nMP with a 27" Apple Thunderbolt display - With firmware 22.2 ?

    If so - Do you encounter "Sleep Wake Failure" ?

    I'm on my third Mac Pro Late 2013, and i finally narrowed the error down - Whenever this display is connected, the machine will reboot itself while in sleep mode.

    This doesn't happen when my newest Thunderbolt display, with 26.2 is connected.

    I'm using a Thunderbolt Display 22,2 with my QC/D300 nMP. I had some problems with the display getting stuck in a mode where no input was possible (although the mouse cursor could be moved). These problems disappeared when I changed Energy Saver settings to: (1) Never let the display go to sleep by itself; and (2) Enable the Power Nap feature. I usually put the nMP to sleep at night, waking it up the next day without problems.

    You may want to fiddle a bit with the Energy Saver settings to see if that makes a difference for you as well.

    Thanks for replying.

    But kinda just wan't it to work out of the box.

    There's no problem, when it's only connected to a Thunderbolt display with firmware 26.2.

    Anyone else having issues?

    I have the same, and I have occasional troubles getting out of sleep and few reboots. I notice that my computer reboots more frequently when I'm streaming Airvideo via airplay to my Apple TV.

    Something is definitely fishy with the restarts but mine happens very few times I haven't bothered bring it in. I'll probably just submit a report to apple.

    *facepalm* So you are having issues, someone gives you something to try. Why not try it? If it fixes the problem, then report it to Apple and wait until they release a fix.... At that point you can put the settings back to their original "out of the box" settings. Clearly it isn't working AS IS, and no one but Apple can "fix" a firmware issue right?
