The MacBook Pro 2021 screen automatically reduces brightness if it detects temperature problems

Apple has shared a new support document dedicated to the MacBook Pro 2021, where it explains the meaning of an alert icon that may appear on the screen of said equipment under specific situations. This icon indicates that the screen has automatically reduced its brightnessdue to excess temperature.

As we can read in the official Apple text, this occurs both in the Liquid Retina XDR Display panels as in the Pro Display XDR versionand it is a prevention measure that is activated without the intervention of the user because its objective is to avoid possible damages derived from excess heat.

As you may have imagined, this move by Apple has not been accidental. The apple company has published that information as a reply to the growing number of users who were reporting this problem, and has given a series of guidelines that should help them solve or mitigate, even if only partially, this problem. These are the official Apple recommendations:

  • On a MacBook Pro with a Liquid Retina XDR display, close any applications that might be consuming a lot of resources.
  • Use the Apple XDR Display or Pro Display XDR reference mode, unless your workflow requires a specific mode.
  • Try to lower the temperature of the room.
  • Close or hide any windows with HDR content.
  • In the Apple menu select the “Suspend” option. This will cool down your computer if you leave it on for at least five minutes straight.

Apple has also commented that those users who have this type of problem frequently, and even when the temperature of the room is below 25 degrees C should contact technical support directly.

We can understand that this protection mechanism is activated under very specific circumstancessuch as if we are using the MacBook Pro outdoors in the middle of summer, and it is directly in the sun, or also if we use it to move demanding applications in a space where the temperature is very high, but it seems that they are taking place cases in which its activation occurs abnormallyand that indicates that there is a problem, either software or hardware.

In any case, the answer that Apple has given has been correct. If you have had this problem and you have any questions, I recommend that you also contact Apple technical support, since a MacBook Pro is a significant investment, and it is better not to put it at risk.
