  1. OLED Brightness Control
    • Brightless Slider shown & Brightless shortcut work but OLED brightness never changed
  2. OLED Sleep & Wake

    Seems like OLED brightness issues. not sure other screen is work or not.

    • Sleep is working, but built-in screen will be black screen when wake.
  3. HDMI hot-plug
    • Problem
      • Can\’t resume to single monitor mode when remove HDMI monitor, and virtual desktop in external monitor will be loss.
      • HDMI monitor will be black except mouse indicator when re-plug HDMI monitor.
    • Workaround
      1. Enable mirror mode in Preferences-Monitor-Arrangement before remove HDMI monitor to avoid virtual desktop loss in external monitor.
      2. Use built-in screen to toggle screen resolution in Preferences-Monitor after re-plug HDMI monitor. External screen will light soon.
  4. SDCard Reader not working – Need to test Sinetek-rtsx.kext
