    I mentioned several times after iMac is in sleep mode -does not want to wake up! Just stay dark screen and I have to unplug the power cable in order to start it again. .. (10.10 beta version). Any similar problems ?

    This is a new bug for me as well.

    2013 iMac 27" 10.10 (14A298i)

    I don't unplug mine, as the machine is powered up because my USB mouse light is still illuminated.
    I just hold the power button down for a few seconds, until the mouse lights turns off. Then 1-2 seconds and I press again to turn it back on.

    I reverted back to Mavericks because of this bug. I also noticed when in sleep the LAN wasn't reverting to 100mbps and sticking at 1gbps.

    having same issue with 2012 MBP...and I thought things were going so well those first few days! This is really the only major bug I've hit. I'm assuming that if I set the computer to never sleep (but continue to allow the display to sleep) that it won't occur.

    Same here with 2012 MBA, takes about 20 seconds to wake, if exhausted and plugged into AC, even longer. Twice I've had reboot loops and off centered login on wake when connecting to AC from exhaustion. Have filed 2 bug reports.

    I have had this issue since ML on my MacMini and now a nMP. I have tried everything I have found all to no avail so I just don't use sleep mode anymore except for the display of course.
