I do not know why I've encountered this problem.
I tried a lot and talked with Apple, but this problem continues.
Please watch this video ( Screen Recording | When i was working ):
How to fix it ?
- Reset NVRAM = Done
- Reset System Management Controller ( SMC ) = Done
imac 5k 2017 = Version 10.13.4
