I just upgraded to Sonoma. My M1 Pro 16 is intermittently charging. I've plugged in the Magsafe several times. The charging mode cycles - 3 seconds on, 3 seconds off - seen by the icon changing and screen brightness increasing then decreasing.

Troubleshooting MagSafe Charger:
A. Start here: If your MagSafe Cable or Power Adapter isn't Working - Apple Support
B. Boot in Safe Mode:
[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, seeing if you still get this error.
C. Try a New Admin User:
What happens when you create a new administrator user, and log int it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.
D. Reset the SMC and your NVRAM:
(Applies to Intel-Based Macs Only)Sometimes when changes are made to the system(i.e. Updates), system configurations (i.e. for the Trackpad) become manipulated, technically. So, reset the SMC and NVRAM. Try performing each thrice. It may take some time, being certain you have the time to perform these resets.

Many people have the same problem.
It is that the Sonoma system deliberately restricts third party MagSafe cables!
Well except this is a factory charger and cable, came in a new M1 Pro ... ?
