Apple states that the screen brightness of the MacBook Pro 2021 would decrease if it becomes too heated.
Apple has updated its support website to emphasise that the mini-LED display on the 2021 MacBook Pro will automatically reduce its brightness if it becomes too hot.
In addition to the Pro Display XDR monitor, the automatic safeguard applies to the Pro Display XDR monitor as well. When the automatic safeguard is activated, users will receive an on-screen warning with an explanation mark in the menu bar. If the room’s ambient temperature is high and you’ve been watching very bright material for a lengthy period of time, this may happen, according to Apple.
What is the brightness of “extremely bright”? As for brightness, the latest MacBook Pros are capable of producing 1,600 nits of peak brightness and up to 1,000 nits of sustained full-screen brightness for HDR material, whereas SDR content is only capable of producing 500 nits of sustained full-screen brightness. Because of this, it does not seem to be a widespread issue, as shown by the fact that there were just a few reports online at the time we published this piece.
Nonetheless, if you find yourself confronted with the brightness warning, Apple has some suggestions on how to get rid of it.
First, close any applications that “may be using substantial system resources” to see whether it is a particular piece of software that is causing the brightness restriction to be activated. Apple suggests that you “close or hide any windows that contain HDR information” and to utilise the screen’s reference mode “unless your existing workflow necessitates the usage of another reference mode.”
Because heat is the source of the brightness limiting, Apple also recommends that you lower the temperature of the room — or, more likely, transfer your MacBook Pro to a cooler location — to avoid the problem. Finally, Apple suggests that if you put your MacBook to sleep for five to ten minutes, it may have cooled down enough to allow you to restore the full brightness of the screen.
If these issues continue and your home is not consistently 77°F or above, Apple recommends that you contact customer service since it might be an indication of a more serious problem with your computer.
Apple’s decision to make this help page available at this time is a bit of a weird choice of timing. As previously said, it does not seem to have been prompted by numerous complaints, and although the 2021 MacBook Pro is still relatively new, the Pro Display XDR, which is also affected, has been on the market for more than two years.
Possibly, as the winter months draw to a close, Apple is ready itself for the issue to become more common as temperatures in North America progressively get closer to the 77°F danger zone.

What Apple recent say for Pro Display XDR and 2021 MacBook Pro
New support documentation from Apple describes a warning sign that might appear on the MacBook Pro with Liquid Retina XDR Display or the Pro Display XDR when the screen is running too hot, causing the brightness to be reduced as a result.
It is explained by Apple that a warning icon in the menu bar or the Display menu in Control Center on a 2021 MacBook Pro or an Apple Pro Display XDR indicates that the display is in low power mode and “uses reduced brightness.”.
This condition may arise if the room’s ambient temperature is high and if the space has been exposed to bright material for a prolonged length of time. When a warning appears, Apple provides numerous options for users who notice it, including reducing the temperature of the room and briefly putting a Mac into sleep mode to enable it to cool down.
- Any applications on your MacBook Pro with Liquid Retina XDR display that are demanding substantial system resources should be closed.
- Unless your present process necessitates the use of a particular reference mode, use the Apple XDR Display or Pro Display XDR as a reference mode.
- Reduce the temperature of the room’s ambient air.
- Any windows containing HDR material should be closed or hidden.
- To put your Mac to sleep, go to the Apple menu and choose Sleep. Allow your display to cool down for 5-10 minutes before pressing any key on your keyboard to bring your Mac back to life.
Users who have this difficulty on a consistent basis when the room temperature is less than 77 degrees Fahrenheit should contact Apple Support for assistance, according to the manufacturer.
