Cannot play videos in in macOS Finder
After contacted Apple Support I got this problem resolved, by using the following steps.


Shut down Mac
Unplug all external devices. To me they are bluetooth keyboard and trackpad
Start Mac and hold on Command + Option + P + R immediately
Mac tried to restart (the screen turned on and off)
Release Command + Option + P + R, let Mac restarted


"Command + Option + P + R" cleared PRAM and let Mac re-exam all hardwares and build correct info into PRAM.
