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.

same here - after update to latest Teams Client (version 1.3.00.21753) - please (!!) fix!
It's a shame, although I like Teams for its features, I really hate it in the meantime whenever I have video calls. Please fix this!
I'm kinda confused about the point of the 14 August update from Microsoft. It appears to say "we fixed some stuff, but not the stuff you're complaining about".
Teams is still abysmal on my 2020 MacBook Pro 13" with external 4k monitor. Nothing in recent updates has improved this at all.
Colleagues with Mac must be on mute on Video meetings just because the noice from the fan is o disturbing. You really need to fix this. It is a matter of protecting your brand. Please Apple and Microsoft, make a team effort of this.

I shut off the new meeting experience hoping it would fix it but no - CPU is going nuts, fan spinning hard whenever video is running. Please fix, it didn't used to be like this.
Update: I just updated to the new version. Yet, when having a video call, my cpu is fully utilized by that call (see screenshot). Any fix to this would be appreciated.
I notice that using the web version, cpu consumption stays low. However, on the web version, I can only see the currently speaking participant.
A fix of this performance issue would be highly appreciated.
thank you for working on this issue. I just checked and the latest update reported to me by the Teams app is from August 3rd.
When can we expect that update to arrive on our machines?
My company uses a lot of Macs and on a daily basis I hear reports of performance problems with MS Teams. A fix to this would really help us in our everyday work life.

I hate using Teams because of this. I'm trying to convince our company to use something else.
Everyone in my company is complaining about this issue, macs and windows users... I see some employees getting in the meeting through their phones to avoid getting their macs or windows unusable... and of course some employees are starting to run parallel conf call with zoom and google meets even when those systems are not allowed for internal meetings... this is a problem that is been around for months and is getting worse and worse. This is completely unacceptable and I hope MS will find a solution soon or we’ll have to switch to other platform.

Same issue here. Only app that does this to my MacBookPro 2018 and only since last update.
VERY annoying when trying to use built-in mic especially since Teams doesn't have any background noise threshold...
I have this problem too, even after turning off all other apps and browser, and external screen - My MacBookPro 3.1 GHz intel Core i7 shouldn't have a problem with one app running! It's crazy. Please can you fix this.
I have noticed large resource usage with only 2-3 chats open. When I receive a notification through teams, it can slow down the entire machine until I switch to teams to acknowledge it. I have seen this on both physical machines and VDI.
It appears to mainly be affecting Mac users on our team. Unfortunately that is the developer team who have lost faith in Teams so are staying on skype which is not ideal for the organization. Also the experiments to integrate Teams with our digital insurance platform also failed as the link was too unreliable.

Don't use a MAC with Teams because of this; miss my MAC, please resolve the issue.

Similar experience here on a 2019 MacBook Pro 8 core I9 processor with 64Gb RAM and 8Gb on the graphics card.
For me the problem starts when I run a combo of external screen (LG 5K) and Microsoft Teams, then make a video call in Teams. This causes the process WindowServer to grab most of the CPU, and from there everything goes white hot until I dump the call and unplug the external screen.
I can then safely reconnect the external screen, and all is well until the next video call.
Workaround: I unplug the LG 5K external monitor before running a Teams video call, and the problem does not arise.
This has been doing my head in since lockdown started in March and we had to move to Teams, will MS ever even acknowledge the issue?!

I have conducted testing on our Corporate Teams implementation and found that we have this issue when there is a large chat history between the people in a conversation. The issue does not typically occur when a the participants have not chatted much in the past. It seems to be related to the way teams is loading the chat history and not allowing the user to type until that history is loaded.
Is anyone looking at this? It is almost unusable.... Need testers, there appears to be plenty of folks available to help...
2019 i7 MBP. Teams video call and the battery is empty within an hour!! Zoom video call and you can go all day.
Experiencing same issue in our organisation - Windows 10.0.18363 with feature update 1909 (3-Jul-20). Users pre-update do not seem to have this issue.
