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.

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...

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.

Agreed Teams performance went way down after installing Catalina. Video freezes when receiving Teams notifications. App constantly says "bad network connection" even when I know the connection is fine.

Vote here for the same issue, it may get more attention from MS:

When I am running MS Teams on Mojave and Teams is minimised, it is using 20% CPU and OSX core process WindowsServer is running at 30% CPU. When I kill the MS Team process WindowServer goes down to about 1%.
All other apps on my OSX use minimum CPU when they are minimised. For example Slack using 0.1% of CPU.
So whatever MS Teams is doing it is very inefficient.

Bump.
2018 MBP running Catalina. When I'm running the Teams desktop client, CPU is raging high and the OS stops charging the battery. I tried disabling GPU acceleration, and read message notifications, no avail.

I have just started using Teams in my environment, I noticed when I have a meeting where I am the presenter and have more then 6 people with their cameras on during a meeting the application starts becoming buggy as you add more participants with streaming cameras it begins to become unusable for all participants. If you stick to only the presenter having their camera on it seems to perform great as long as there are less then 6 camera streams. Going north of 6 streams and it starts breaking for all users.

Same issue. Seems reproduced when I'm typing and someone else is typing in the same chat. Lags for 5-7 seconds very often. Very annoying.
Mac OS Mojave 10.14.6

The same is happening to my MBP i9 32Gb RAM. This problem, that happens every time I use Teams, makes the computer totally unusable. Bad, bad, bad, ...

Experiencing the same problem. It is extremely draining and the program struggles to keep up with VERY basic things like switching from one conversation to another.
When I type, the program is unable to keep up with what I am typing. After I finish a sentence I have to let it sit for 10-15 seconds to catch up. This issue is exclusive to Teams; I do not have this problem with any other programs.
In addition, over the past few weeks I am having a new problem: New messages coming in are extremely delayed. I am receiving the notification for messages up to half an hour after they are sent. On several occasions I have gotten dozens of notifications all at once after my team discusses a crisis for a long period - and I am useless to them because I don't get the messages. I have resorted to giving coworkers my cell phone number and asking them to text me if there is anything crucial because I cannot rely on Teams messages being prompt.
I initially thought this may be an issue with my work laptop, but after installing the program on my (brand new) personal laptop to see what happens, I have the same problem.I have also been having problems for several months with calls. When someone calls me I hear the sound but see nothing visually until after the call is gone and I have "missed" it. I again thought this may be related to my work computer (perhaps my display settings) but sure enough I have the exact same problem on the new laptop with no external monitors connected or other special settings.
I have followed suggestions such as disabling the GPU acceleration as others have tried... no luck.
