Power over USBC stopped working since upgrading to Monterey

Hey mat88,

Since updating to macOS Monterey, you're no long able to use the monitor to charge your computer. Test in safe mode to see if the issue occurs: How to use safe mode on your Mac. If it works as expected in safe mode, restart normally and test.

If it doesn't test in safe mode, check to see if it works in a different user account. If you do not have another one, set up a test administrator account by following the steps here: Set up users, guests, and groups on Mac. If issue doesn't occur in the different user account, it could be related to settings in your account. You may delete the test account afterwards.

If issue continues, reset the SMC: How to reset the SMC of your Mac.

Hope this helps. Take care.

Yes same here; Got the PHILPS 346P1CRH/00 and a MacBook PRO A1989 "Core i5" 2.3 13-Inch (Mid-2018 True Tone Display, Touch Bar, Four Thunderbolt 3 Ports)

Hope this will be fixed soon!

Regards,

Danny

Having the same issue with the same monitor but with Big Sur 11.6.1. Worked fine on Catalina and even on 11.6. Reproducible on two Macs (one Intel MBP, one M1 MBA). Searching Mac Rumors and the Apple Developer forums suggest this is a common issue - when can we expect an update to fix this?

Hi mat88,

If the steps above didn't help isolate or resolve the issue, we recommend contacting Apple here: Get Support.

Best wishes.
