Microsoft Teams not working on MacOS

New Contributor



so I downloaded and installed the MS Teams app today (24.2.2021) and it went well. But after the instalation was done and I tried to open the Teams app, it showed me only the small window saying: "Loading Microsoft Teams..." It was like this for about two hours when I realized its not probably gonna work. It doesnt show me the sign in window or anything like that. 


I tried re-installing and also deleting and installing again, but nothing worked.


Has anyone else experienced this? Can anyone help?


Thanks a lot.

Hi, thanks for sharing those links. On one of them I found that people are having the same problem, but there was no answer or reply with tips/ instructions on how to fix it. 


So I found out that people have the same problem, but I havent found any solution to it. 


Anyhow, thank you for your input. I really appreciate it.

Hmm...sorry about that, I should have read through every entry. You might want to just go to tech support site for personalized service. When you give you a response, it would be great if you could post it here.

Yes. I went trought a lot of other sites and today I have found an answer to my prayers. :)
So, to make it work - for anyone that might be having the same issue - Just open any invitation to a call/ meeting or any notification about being added to a new Team in your emails, and it should open the MS Teams app with "Sign In" window and then it should be working. This helped me, so I hope it can help also anyone that might be having the same problems. :)
You painstakingly went to "a lot" of sites and all you could come up with for a "Fix" is to open the Teams invitation that's not opening my Teams? SERIOUSLY???
This is like telling somebody that being thirsty means you need something to drink. I KNOW!!


The answer is simple: Teams is a piece of s..t. It is just unusable on MacOS. MS makes me angry whenever I try to use any MS products.

I've been using Teams on my Mac desktop and laptop for over a year (following the instructions you describe here = pretty straight forward). Just last week - for no apparent reason - it stopped working with exactly the same symptoms as above: it gets stuck loading Microsoft Teams. I have just uninstalled and reinstalled the application and it still has the same problem.

If Microsoft wishes to remain in the game I strongly suggest you find a solution to this problem, as Mac users will increase pressure on the industry to use other platforms to meet if this persists.

@amandasheedy I have the exact same issue - been using it for >1 year and stuck loading. I have tried every solution out there to no avail.
