Teams is KILLING my Mac Every Day

I have a hard time believing I'm the first person to post this after not finding anything in the forum.  I wouldn't doubt if Microsoft is deleting them because they can't figure out how to fix this i...

    Hi everyone, we're pleased to announce Microsoft Teams for Apple Silicon, which on the M1/M2 ARM builds, will have significantly faster performance than what's seen during the Rosetta emulation today! Here's our official roadmap ID for this release; Microsoft 365 Roadmap | Microsoft 365. More on this can be found here; Announcing Microsoft Teams optimized for Apple silicon - Microsoft Tech Community. 

    Users should see a significant performance boost with this release. And for the Intel Macs out there, we're still thinking about you! We have some large performance fixes coming that will help improve overall performance for the Intel version as well. 

    Thanks,
    Sam Cosby, Teams Engineering PM

shilocase I'm experiencing these symptoms on daily basis. Today, the situation was so unbearable, that I tried to google a bit and seemingly found a solution that worked for me.

 

In my experience, MS Teams is one the most demanding app that I've ever run on my MacBook Pro (Retina, 13-inch, Early 2015, 3,1 GHz Intel Core i7, 16 GB 1867 MHz DDR3) - using the CPU regularly up to 50 % for a lenghty period is no exception. Affinity suite, Final Cut Pro X or even Half-Life 2 games have never done this to me...

 

Along with that, my setup includes external Apple Thunderbolt Display. I usually keep MacBook's lid closed and also the computer is in plastic protective case. I've noticed that when Teams starts to "kill" my MacBook, the fan runs also at high speeds. So I figured out that the system may be overheated and simply throttles CPU performance in order to cool itself down (https://appletoolbox.com/check-if-mac-is-thermal-throttling/).

 

After opening the lid, removing the bottom part of the protective case and opening window to the outside (to let some cool air in), the MacBook returned back to normal operational performance within about 10 minutes. Fan slowed down, system is responsive again. Including Teams meetings with video and screen sharing :cool:

 

I believe that M1 MacBooks have better CPU / temperature / cooling management so the symptoms usually won't appear on these machines. That being said, I'm still convinced that MS Teams really deserves some serious optimalizations.

 

Hope this helps...
