[Solved] 7280 OpenCore BigSur Post Install Issues.


Recommended Posts

I upgraded from Clover/Catalina to OpenCore/BigSur.    It was easier than I expected and the file and configuration are much cleaner with OpenCore. 


The system works fine except for:

  1. Screen Brightness Button.  Fn+Up and Fn+Dn used to work under clover.  But I have not been able to apply the same changes to OpenCore (BRT6??)
  2. HDMI and DP connectors are not working. (Black Screen).   I am Working on this now.
  3. Sleep is flaky.  Closing the lid does not put the laptop to sleep.
