Hi Guys,
I have purchased Macbook pro M1 and occasionally (once a few days) having issues with light sensor so that in relatively bright and sunny room the brightness level of the screen suddenly goes from 80% down to 5% or so I can barely see anything.
Closing and opening back up the lid seems to solve the problem, or rebooting the laptop as well. I am wondering if I should bring the laptop to Apple Store so the guys can check the sensor itself or it might be something else.
Cheers
Have you tested any further— making changes to
>System Preferences>Turn off "Automatically adjust brightness"
To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal and test as caches get rebuilt.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
You can always get a free over the counter 'Apple Service Diagnostics' test /assessment if your issue continues.
Make an appointment for a "hardware issue"—
