    Hi, all,

    I have a bizarre problem with my Mac Pro.
    After the Mac goes to sleep, the keyboard is no longer recognized when the machine wakes up. First the basic details

    Computer: new Mac Pro (Cylinder)
    Keyboard: USB Das Keyboard 4 Pro (Mechanical)
    OS: OS X 10.10.1
    Mouse: Logitech MX with USB unifying receiver.

    1. Computer will only wake via mouse event or power button.
    2. Keyboard does not wake computer.
    3. No keyboard input after wake, so no way to login since I cannot enter the password.
    4. Unplugging keyboard and plugging in again fixes issue until next sleep cycle.
    5. Happens on all USB ports, both on the Mac Pro and on the Thunderbolt displays connected to it.
    6. Happens on all keyboards tried (I have tested with 6 mechanical keyboards of different brands.)

    Now for the weird part ...

    This only started happening after I moved houses, so the computer was disconnected and moved to the new location.

    The exact same hardware/peripherals had no issues prior to the move.

    My only guess is that some setting has changed, but I don't know where or how that could have happened.

    Any ideas?

    I have this too and have seen more reports of if recently. It's a Yosemite bug.
