Poor performance on MacOS
I can't use teams with out it lagging severely. When I go and look at the processes running, It always looks like the 'helper' is taking up crazy amounts of CPU and it lags out the application to the point of it almost being unusable.
I've tried closing the application, rebooting, re-installing, checking for updates, etc.. nothing works.
I'm on macOS Mojave 10.14.2
Thank you for your feedback. We are continually looking to bring performance boosts to the Mac Client, including improvements with Electron 10 that are releasing. We are also aggressively addressing other areas of performance around the Mac client
Spent hours on the weekend setting up my MacBook pro for work. First Mon 9am Teams meet - noone could see me, I couldn't see me. I could switch on the microphone but looked like I was muted. Even then my colleagues couldn't hear me over the roaring of the fans as Teams used ridiculous amounts of CPU. Then whole thing crashed, couldn't shut down Teams - had to shut down my MacBookPro instead. What is wrong when my powerful Macbook Pro can't do Teams but the low specced SurfacePro (which I let someone else have to work in lockdown) can?
Yep - this is killing my M1 MacBook Air! Performance isn't badly affected but it gets super hot! I love Teams but honestly, I'm going to need to use a different solution if this doesn't get fixed quickly... And just to be clear, it's not Teams in general it's Teams being used for video-calls that's the problem...
Or how about you lazy effs port Teams over to M1 macs?

My machine sounds like it's about to fly into space.
This has been the bane of my existence for the past six months. Every call. EVERY call, I am the one who has a gigabit connection - and yet I am the one who cuts out. I've looked at every aspect of my machine and network and finally found this blog that says that it's a Mac issue and Microsoft has said they would fix it (in March). https://www.windowslatest.com/2021/03/29/microsoft-teams-will-soon-run-faster-on-your-macbook/
PLEASE, Please fix this.
Well I'm going to be deeply disappointed to not see the 3 year birthday of this issue. I recently discovered that the teams uservoice is intended to close down in October 2021. So we are at where feedback is closed before issue is corrected.

Anyone complaining about this is clearly using MS Teams wrong.
Microsoft created a transformative piece of software that helps convert you computer into a space heater and you are using them for messaging/collaboration?
Please, just open MS Teams, let it warm up your house and enjoy your computer burning down after 3 months while sending endless data about you, your work and every telemetry values under the sun back to MS servers.
Same problem...Macbook ist heating up like crazy ....

Using up > 80% of my cpu for "Teams Helper (renderer)" is way too much. Using teams brings my Mac to a crawl.
(Edited) In addition, sometimes it takes me 10s for my mouse clicks to register. Like when I want to view another chat.
I'd like to chime in that the CPU usage when in multi-person video calls is quite excessive. However, since about a couple of weeks it has gotten (much) worse.
Besides the Teams Helper (renderer) process taking up >80%, 'kernel_task' is also spiking. This causes major video glitches (black frames and for some frames the video even turning black & white?) and the entire system to become unresponsive. Looks like something is going completely wrong GPU-wise.

Teams MacOS client is essentially unusable on BigSur with multi-person video conferencing. Can see delays (lag) of 20-30 seconds between audio and video. Screen sharing feature brings machine to its knees causing other apps/services to stop responding (Bluetooth, Outlook, browsing). Running MBA 2019 i5/16Gb ram. Have tried uninstall/reinstall, disabling GPU, closing all other apps while using teams and nothing has helped. I recently tried moving the Teams window from my DisplayPort external monitor to the laptop display and that seems to have reduced the lag somewhat (down to 5-10 seconds), but still not usable. This thread is 935 days old and the last post from engineering was March, not feeling the "aggressively addressing" thing.

Any more news? This is a constant issue with our Mac users, with fan-noices because of the Teams helper interrupting meetings and concentration.
@Timbob - which alternatives are you looking at? I would be interested. I had a number of people still me Teams is a good app, however once we switched we have had nothing but problems. It's a shame really, because I moved everything over to Microsoft 365 and I am not happy with the switch.
Specifically Teams/MacOS related - I get lagging up to (and over) 10-15 mins. It is awful and looks horribly unprofessional on my company. My Mac computers run multiple CAD programs all day, everyday with no issues. I open Teams and screenshare (no other apps open but maybe 1 chrome/safair brower and outlook) and my computer can't handle it.... there is something wrong with Teams if my computers can't handle it.
I'm also seeing the same issues as @Tommiy. When I change the display scaling to the default setting, the performance hit seems to be a little less noticeable.
Teams is still very slow, but the display scaling seems to aggravate the issue, specially when screen sharing.
I've noticed that really its a combination of macos and teams. Macos scaling for the display is an issue. I have a 2 external monitor set up with a 2560x1440 thunderbolt and a 4k (set to look like 2560x1440) and the CPU usage doubles just dragging a teams call between one display and the other. I'm putting it down to the fact that on the 4k screen with the sub-integer rendering in macos causing the 2-3x cpu increase in load. I'm not sure if others are using the internal retina display but to be honest it actually seems to cause more load than the naive 2560x1440 native monitor. It would seem that this will never be corrected because in my case seems to be a combination of teams and macos. I wish macos handled scaling like windows. The later reales the handling is getting worse by all reports that scaling and fonts being blurry is a big issue. No solution here.
The whole desktop application is very laggy and takes lots of CPU. We are working on latest Intel i7 Macbook Pros and it is very disappointing how slow the Teams application is.
If that cannot be fixed using the existing Electron platform maybe it is time to write a native desktop client.

Same problem here. Possible workaround for the others suffering from this: when I used Edge on my mac to run Teams via the web, it worked like a charm without severe performance degradation. So it seems Electron is the culprit.
Very recognizable. I think it started a few months ago. It did not use to be as bad as today. I use screen sharing in 3 out of 5 meetings. That's when this performance issue is an extreme factor.
I think Electron is a big part. GitKraken Helper (Renderer) is also top of list a lot. GitKraken I can close. Closing Teams is not possible.
My global team, mostly Mac users, are almost finished reviewing which alternative to MS Teams we can move to. Every user has lag problems due to the CPU hogging of Teams Renderer.
Shame really - if it worked, it would be a good app. But I won't be sorry to see it go.

still very much an issue
Any updates here? My MacBook Pro i7 and 16gb Ram is nearly unusable, when Teams is used! This is a shame for MS. Zoom ist running without any issues!
