Question and potential answer. Q: Microsoft Teams on Mac having high CPU usage and fan is going crazy, everything is slow, how do I fix??? A: Do the extra steps to "completely" uninstall teams and reinstall from the right link

Microsoft Teams has been horrible for me for the past year. High CPU usage, fans blazing, computer battery drops by 10% every 10 mins. Someone suggested to do a "complete" uninstall instead of only moving Teams to the trash.

To uninstall Teams, quit Teams by right-clicking the Teams app in the dock, then holding down Option and clicking Force Quit. Open the Application Folder, select Microsoft Teams, and move it to the Trash.

Then:

1) Click Go > Go To Folder

2) Then navigate to following folder and delete them (if any)

~/Library/Caches/com.microsoft.teams

~/Library/Caches/com.microsoft.teams.shipit

~/Library/Application Support/Microsoft/Teams

~/Library/Application Support/Microsoft/Teams/Application Cache/Cache

~/Library/Application Support/Microsoft/Teams/blob_storage

~/Library/Application Support/Microsoft/Teams/Cache

~/Library/Application Support/Microsoft/Teams/databases

~/Library/Application Support/Microsoft/Teams/GPUCache

~/Library/Application Support/Microsoft/Teams/IndexedDB

~/Library/Application Support/Microsoft/Teams/Local Storage

~/Library/Application Support/Microsoft/Teams/tmp

Don't forget to empty your trash to completely remove everything.

return to the official website and re-download Microsoft Teams if you need to. The platform is also available in the Apple app store, but that app is only compatible with iPhone and iPad and not for MacOS.

I've been running my mac for 2 hours and it's only gone down 8%. I tested the video while presenting and it was at 10-12% cpu usage vs 35%+ before. Hope this helps others!
