While streaming Apple+, Netflix, Prime Video, the screen display on my 27"iMac, 21" iMac and iMac Pro is extremely dark. I have troubleshoot this issue with Apple Tecs (3 levels) with no fix. Was told this happens to many users. Is there a software fix for this in the future?
Are you running any VPN, Anti-Virus, or Cleaning apps?
