You need to calm down MacBook Pro overheating will reduce brightness

Documents analyzed by Apple in recent days show that when the display is overheated, it may cause brightness drops, which may appear on MacBook Pro or Pro Display XDR equipped with Liquid Retina XDR displays.

Apple explained that in the control center of the 2021 MacBook Pro or Pro Display XDR, a warning symbol appears in the menu bar or display menu to indicate that the display is on low power - power mode and "use limited brightness".

This can happen if the ambient temperature of the room is high and bright content is played for a long time. Apple offers several solutions, including lowering the room temperature and temporarily putting your Mac to sleep to cool it down.

1. On the MacBook Pro equipped with a Liquid Retina XDR display, quit any application that may consume a lot of system resources.

2. Unless your current workflow requires a specific reference mode, use the Apple XDR Display or Pro Display XDR reference mode.

3. Reduce the ambient temperature of the room.

4. Close or hide all windows containing HDR content.

5. Select Menu - Sleep to put your Mac to sleep. Let the display cool down for 5-10 minutes, then press any key on your keyboard to wake up your Mac.
