Brightness Controls no longer working after Ventura 13.7 Update

M1 MBA. Updated from 13.6.9 to 13.7.

Brightness controls no longer have any effect on the built-in display.

The display stays 100% bright.

I tried the Brightness keys (F1, F2), the slider in the Control Center, the slider in the "System Preferences --> Display" section. No luck.

I found out: After a reboot the brightness controls will not work until you have closed and opened the lid of the MBA. After that they work normally.

MacBook Air 13″, macOS 13.7

Did you try opening and closing the lid? My brightness controls work after doing so (but I have to do it each time I start up the computer now).

Hi,

I'm experiencing the same issue on the M1 Pro / 16GB after upgrading to version 13.7. Closing and reopening the laptop laptop cover helps, but it's annoying. Honestly, if it weren't for the security patches, I probably wouldn't update anymore.

I don't want to update to higher versions OSX because they run slower and use more RAM. I produces music and use VMware Fusion for DevSecOps tasks, so every megabyte of RAM is crucial. I think OSX Ventura is the last good (in terms of performance and RAM usage) one for this version of hardware (m1 pro).

Apple: please fix this problem !!!

Regards,

Kylen

Found a much better solution: Upon booting up, put your macbook on sleep(by clicking sleep), and wake it up. The brightness will work. Hopefully there's an update coming up soon.

I tried it and it worked! Thank you! It's just so hassle to always do that every time I start up the laptop. I fear I'm never going to update ever again after this, it's so traumatic. I really thought I was going to lose my mind

I have the exact same issue. I'm trying to send feedback to Apple, but MacOS 13.7 isn't one of the options in the drop-down menu. :P

Nothing was covering the screen or the camera. It's definitely a bug.

Good work there 👍

There is an Ambient Light Sensor on the Builtin Camera

If that had become covered or partially covered

Closing the Lid and opening again, may have dislodged what was covering the Sensor ?

My M1 MBA updated to 13.7 has the same problem. And I found many people with the same problem. Obviously, it is a bug of 13.7. Hope Apple release a minor update as soon as possible to fix this bug... It is annoying!
