    One of the biggest issues ive encountered with the public beta.

    When waking from sleep, the display remains dark and will not display the password lock window.

    I thought turning the password off for waking from sleep, but it doesn't. Screen still stays dark.

    Everytime I wake the computer from sleep I have to power it off and back on again :(

    Just saw this. I do have Duet installed. Going to try removing it and report back with the result.


    UPDATE:

    It's Duet causing the issues. I uninstalled it and the computer is back to normal and waking from sleep just fine.

    For those experiencing this issue here's the fix:

    1. To fully uninstall Duet, select the Duet icon in the menu bar, select uninstall.

    2. If the computer goes dark and unresponsive after the uninstall, just turn it off and back on.

    3. Problem solved. System should wake from sleep normally now.
