PLEASE fix desktop app performance on macOS!! Constant high CPU usage and memory leaks!
I'm running Teams desktop app on macOS Catalina and the performance is TERRIBLE! If I get on a single 1-on-1 video call, the fan on my 2017 MacBook Pro starts spinning like crazy, CPU usage goes up to about 85%, and app begins to use over 1GB of RAM! To put it in perspective, I can get on a Zoom call with 10 other people, CPU usage is at less than 20%, and memory usage never passes 300MB
I've read on other forums to disable GPU acceleration in the settings, but that has only marginally helped.
Please fix your app!
Thank you for your reports. We released client and service updates this week, that address many MacOS-specific performance issues. We are also aware of recent performance issues with Microsoft Teams meetings, especially on laptops and when using external monitors.
The team is working to resolve these issues. In the meantime, please find troubleshooting information here: https://docs.microsoft.com/microsoftteams/troubleshoot/known-issues/teams-slow-video-meetings-laptops-4k.

Using TEAMS Video leads to so many issues on macOS (Catalina, mabook Pro 2017)
Mac becomes so slooowwww ! Even impossible to open a chat within teams, browse a file in teams, open document to share. UNSUSABLE !!!
What I came to using Intet Power Gadget is that when teams is in video call, it does not trigger the Boost mode of the CPU therefore keeps it under 2GHz and even 1,4GHz in some cases.
Any request for CPU is throttled or not requested in video call with teams.
I am also using everyday/week Zoom & BlueJeans & WebEx on same machine and this does not happen EVER for sure. Mac is still usable in a call with these and CPU is avail.
I also notices that using a second screen, CPU speed request changes depending where the Teams Video windows is located :
- Video window on internal screen ==> CPU gets throttled must of the time and even below 1.4GHz sometimes ==> UNSUSABLE
- Video on external attached screen (thunderbolt) ==> CPU may/can go up to 3.4GHz when needed and CPU is still responsive most of the time.
I attach some screenshoots of the Power Gadget with the described cases
Please solve this, rewrite, change of framework, deliver something that works, all others do so Please !

Performance is terrible on the M1 MacBook Pro. It takes up 700MB of RAM on Big Sur.
Same here: Big Sur 11.4, MacBook Pro (16-inch, 2019); 2,4 GHz 8-Core Intel Core i9; 16 GB 2667 MHz DDR4; AMD Radeon Pro 5300M 4 GB; teams version: 1.4.00.11161
When in meeting, even a 1 on 1 with screen sharing, kernel_task about 400-800%, even saw 4000% flash by at one point...
Was not this bad recently. Can Teams be downgraded?

I have one of the latest MacBook pro: MacBook Pro (16-inch, 2019), 2,6 GHz 6-Core Intel Core i7, 64 GB 2667 MHz DDR4, AMD Radeon Pro 5300M 4 GB Intel UHD Graphics 630 1536 MB
and my Activity Monitor get some 700-800 % CPU usage while in calls in Teams (not always and not immediately. )
I'm running the latest MacOS Big Sur, version 11.4 (it has been an issue for a long time. As soon as I kill Teams the problem is gone. In the picture below, the teams is started right before the CPU load increase

It indeed has become much much worse over the last few weeks it seems. MBP 2018, used to work just fine, is now a drama to use.
Please fix this.
Running the latest version of Big Sur (11.4) on a 2019 8-core Intel i9 MacBook Pro, attached to a 27" 5K external LG display. Conference calls on Teams make my Mac pretty much unusable. It gets so unresponsive that I can't even take notes in BBEdit during a call. Kernel_task CPU usage goes through the roof (> 950%) and the fans start spinning like crazy. I tried quitting all other apps, to no avail. As soon as the conference call stops, cpu usage and fans go back to normal in a matter of seconds, so Teams is definitely the culprit here. C'mon Microsoft -- I can have conference calls on Zoom with 100 people and my cpu usage is barely affected.
This is still an issue for me. OSX 10.14 and 10.15.

My Mac doesn't like Teams. The audio on my Chrome disappears (?!). It often won't recognise any of the camera (a Microsoft camera!) or microphone hardware attached. I usually have to reboot my 2018 MBP after a Teams meeting to get my MBP back to normal functionality.
Very tiresome performance on Mac OS. Using very powerful but old MacBook Pro [mid 2015, i7, 16gb ram]. Terrible video performance, worse audio. Sync issues. Google Meet working perfectly. Not just bad performance in Teams but total resource hog and can't do ANYTHING else while on a call. Pretty much unusable and unacceptable.
This appears to have resurfaced / gotten worse a lot recently again, can you please post a status update here on your progress to address this?
Ivan Fioravanti commented
Same here! Teams on MacOS is useless! During calls it started hogging the CPU causing the fans spin to the max and Teams started to flicker and my webcam started lagging on my MBP 2019 with Core i9! How can this be possible?
Kernel process had to jump in to slow down CPU temperature trying to keep Macbook cooler. Please fix this.
I was going nuts end of this week since my Teams during calls started hogging the CPU causing the fans the spin to the max and Teams started to flicker and my webcam started lagging on my MBP 2019 with Core i9! I already tried to resolve it by deleting Teams, cleaning cache and removing all Teams folder/files and did not resolve the issue. So Yesterday, as last resort completely wiped my macOS and reinstalled Big Sur, and guess what? The same issues started to re-appear: High CPU load, slow response, lagging video, OMG how can I continue to work from home like this?
Seems I'm not the only one since a lot of colleagues are also complaining.
Please help, tell me how to support you to debug this issue?
MacBook Pro (15-inch, 2019)
Processor 2,3 GHz 8-Core Intel Core i9
Memory 16 GB 2400 MHz DDR4
Graphics Radeon Pro 560X 4 GB
LG HDR 5K monitor
Logitech C930e webcam
i have been dealing with this issue for months and tried everything from disabling GPU hardware acceleration to closing every single app down and only having Teams running. Still the same issues:
1. Laggy video conferencing which has a knock on effect on all other applications that are running.
2. Fan running on maximum.
3. Overheating to dangerous levels
it wouldn't surprise me if there is a lawsuit seeking compensation against MS from Mac owners who have experienced a catastrophic failure due to running Teams.
Is anyone from MS even monitoring this channel anymore?

Latest MacBook with M1 processor and 16GB RAM. Of all applications, Teams is using the most memory by far, taking up between 1.5 and 3 GB of memory depending on how long it has already been running - and that's just the "Microsoft Teams Helper (Renderer)" subprocesses.
I would consider even the 1.5GB as totally unacceptable.
Big problem of slowness of Teams on my macbook pro
Our company switched from BlueJeans (which worked very well on my Mac) to Teams and since then it's been a pain to follow meetings with colleagues. Please solve this bug

I have a 2020 MBP (i9, 8-core, 32GB RAM) and it has fans at max with Teams out. I have tried disabling GPU but it does not help. Have already disabled all animations, spell check etc to keep usage low.
Will Microsoft ever fix the issue for Mac users, or should we request our organizations to buy/provide as a 64-core 1TB RAM machine just to make video calls?
Richard Collette commented
Still an issue. Mid 2021 on Mac.
Martin Norin commented
So what is the status of this issue? It has been over 1 year since the report came i. Microsoft have had plenty of time to resolve this issue, but no real solution has been delivered.
is there a status please?
Microsoft Teams has now been updated to Electron 10 in the Public Preview Channel.
It just blows my mind that this is still an issue. Like everyone else, Teams causes fans to max out on both my high spec 2019 MBP 16" and high spec 2020 MBP 13". It even causes the CPU to throttle on my MBP 13". It's obviously caused by the encoding of my camera (turning off the camera makes the fan speed / CPU temperature return to something more reasonable), but that's as stupid a workaround as telling a car driver to turn the engine off if they don't like the noise.
I notice that Teams has recently added a "Call Health" tab. It shows "Video processing" is "Software enabled". I DO NOT have the disable GPU option set in preferences. Modern machines, great hardware encoding capability and yet Teams decides to software encode the video image? No wonder the fans scream.
No comment since August 2020. Gimme a break - when you going to fix this Microsoft??
