MS Teams Helper using up >100% of CPU MacBook

Since the latest update of MS Teams (current version 1.3.00.9271 updated on 07/05/20) on a MacBook (early 2015), every time I now join a Teams call, the Microsoft Teams Helper is using >100% of CPU and causing the laptop to overheat. I have disabled the GPU acceleration as seen on some other message boards but this has no impact, and could do with a fix for this ASAP.

Many thanks in advance.

    Root cause of mine turned out to be a gaming mouse I was using. Hard to diagnose, though, because the problem didn't always manifest immediately and it seemed to be dependent on my resetting teams.

    Here's how I got to the bottom of it:

    1. Unplug everything but power - monitor, USB accessories, etc. Open Activity Monitor so you can check Teams' CPU usage.
    2. Start up teams. Does it still eat your CPU? If not, then this is not going to help and you've got some other problem.
    3. Stop Teams.
    4. Plug in one peripheral and start Teams again. Use it for 10 minutes.
    5. Does it still eat your CPU? If yes - you've found your problem.
    6. If not, stop teams again and repeat for every peripheral you use.

    Hopefully this helps someone.

    Having the same issue in 2022, for almost 2 years now. How do we get MS attention to this ? Ridiculous

    MacOS 11.5.1 does not resolve the Teams CPU issues when video is enabled. I think this is an issue with Teams because I do not have the same problems with Zoom.

    EwiPi your script is a good idea but it's a little broad - it'll catch renderers used by other apps also built on Electron. I've slightly modified your script as shown below:

    #!/bin/bash

    my_array=( $(pgrep -f "Microsoft Teams Helper (Renderer)") )

    for i in "${my_array[@]}"; do

       renice -n 10 -p $i

    done
