I normally use web teams for comms as i found it used to take less resources. Some where in the last 4 days microsoft has updated Microsoft Edge to version 134.0.3124.51 which has resulted in web Teams heating up silicon Macs to high 85C and making the fan whirl. This is almost the only time i can say I have noticed the fans running. After a while the mac crashes and reboots. I have tried this on both a M1 Max and a M4 MAX using this version of edge; both behave identically.
If you create a plist so edge does not update, then send edge to the trash, and install version 133.0.3065.69 and then run web teams again you will find that with dual external displays that the cpu temperature sits about 62-7C.
I also tried this on a brand new account that never had edge previously installed and had the same behaviour. there is no easy way other than feedback to microsoft to report a problem. Hoping this assists some one else.
