MS Teams Helper using up >100% of CPU MacBook

its 2023 and i still have the same problem (macbook air m1)

I wrote a bash script along with 'cpulimit' via Homebrew to stop it from overusing CPUs. Had to do the same for OneDrive. while it does slow MS teams down a bit, my mac remains usable. YMMV

#!/bin/bash
while [[ 1 ]]; do
clear
date
cpulimitpids=ps auxm | egrep -v "grep" | egrep cpulimit | egrep "pid=" | tr -s " \t" "\t" | cut -f 15 | tr -s "=" "\t" | cut -f2

echo OneDrive:  
uppercasename=ONEDRIVE  
apppids=`ps auxm | egrep OneDrive | egrep -v grep | egrep -v "File Provider|FinderSync" | tr -s " \t" "\t" | cut -f2 | sort -n`  
for apppid in ${apppids[@]}; do  
     FOUND=`echo $cpulimitpids | tr " " "\n" | egrep "^$apppid\$" | wc -l`  
    if [[ "$FOUND" -eq "0" ]]; then  
        cpulimit --limit=100 --lazy --include-children --pid=$apppid &  
    fi  
    echo ${uppercasename}:  $apppid  Found:  $FOUND  
done  

echo Teams:  
uppercasename=TEAMS  
apppids=`ps auxm | egrep 'Microsoft Teams Helper' | egrep -v GPU | tr -s " \t" "\t" | cut -f2 | sort -n`  
for apppid in ${apppids[@]}; do  
    FOUND=`echo $cpulimitpids | tr " " "\n" | egrep "^$apppid\$" | wc -l`  
    if [[ "$FOUND" -eq "0" ]]; then  
       cpulimit --limit=100 --lazy --include-children --pid=$apppid &  
    fi  
    echo ${uppercasename}:  $apppid  Found:  $FOUND  
done  
sleep 60  

done

the problem is THEY DON'T CARE what benefit is it to them to sort it.

People - I found the bug and some kind of a solution with the help of seo-praxis.de

Main question: If you are joining a teams meeting, your pc is getting very loud, and slow?

Question 1: Do you use Teams MacOS App?

Question 2: Do you use external screens?

Then the solution might be working for you as well.

Step 1: Go into an empty meeting/test with a friend & close all other Apps beside Teams.

Step 2: Open "Activity Monitor" and watch CPU usage.

Step 3: Wait until the mac CPU usage is getting high (>50%)

Step 4: Don't get angry.

Step 5: Disconnect all external monitors.

Step 6: Wait 1-3minutes (it sometimes takes a while).

Step 7: Your mac should now be down to <20% CPU usage and you can have the meeting normally.

Since the Team around Teams is obviously not able to fix this bug since 2 years..

at least the solution will enable you to take part in meetings again.

Hi,

Any update on this? 

My mac is on fire every time I use MSTeams for call.
