I recently noticed a problem with my computer. TrueTone and automatic brightness stopped working. I tried everything: restart, hard restart, safe mode, system reset, creating a new user. All Mac components are original and have not changed.
Computer: MacBook Pro 13" M1 8CPU|8GPU|16GB|1TB
Mac OS: Bug Sur 11.5.2
Battery: 100%
That I see in settings:
I tried to run a diagnostic on my mac and got an ALS 001 error message. From this source, it means "There may be an issue with the ambient light sensor." Okay, let's go to the service center, unfortunately, the laptop was still defective.
