Pro Display XDR and 2021 MacBook Pro Users Can Experience Limited Brightness in High Temperatures

Apple has shared a new support document explaining how a warning symbol can appear on the MacBook Pro with Liquid Retina XDR Display or the Pro Display XDR when the screen is running too hot, which will result in brightness being diminished.

This can occur if the ambient temperature of the room is high and you’ve been playing very bright content for an extended period of time.

Apple has made available some suggested solutions for those unlucky users that experience the issue with their displays.

  • On MacBook Pro with Liquid Retina XDR display, quit any apps that could be consuming significant system resources.
  • Use the Apple XDR Display or Pro Display XDR reference mode unless your current workflow requires a specific reference mode.
  • Lower the ambient temperature of the room.
  • Close or hide any windows with HDR content.
  • Choose Apple menu  > Sleep to put your Mac to sleep. Let your display cool down for 5-10 minutes, then press any key on the keyboard to wake your Mac.

If the issue continues and the ambient temperature of the room is less than 77° F, contact Apple.
