Microsoft Teams not working on MacOS
- Feb 25, 2021Yes. 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. 🙂
These instructions on howtoisolve dot com solved the problem for me:
Remove the cache associated with the Teams App. The system and app-generated cache files make the operation smoother and faster. However, not all the time, cache benefits the system and could create issues while using it.
Finder stores all the cache files and folders of applications installed in Mac. We’ll remove the cache from the Finder and restart the Mac.
1. Open Finder.
2. Click on Go > Go to Folder.
3. Type ~/Library/Caches and hit Return key.
4. Locate and remove com.microsoft.teams folder.
5. Likewise, navigate to the ~/Library/Application Support/Microsoft/Teams and delete the following folders:
* Application Cache/Cache
* blob_storage
* Cache
* databases
* GPUCache
* IndexedDB
* Local Storage
* tmp

Took a while before Teams started up after that, but at least it did…
