Hi berrynotec,

the files you're encountering are high-likely temporary files generated by Microsoft Teams during its operation, with the .yuv extension indicating their association with video data, possibly from video calls or meetings.

It is unusual that these files are not automatically cleaned up by Microsoft Teams.

1) Ensure your Microsoft Teams application is up-to-date, as newer versions may resolve such issues.

2) Clear Microsoft Teams cache:

Classic Teams

  1. If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command (⌘)-Q.

  2. In the Finder, open the /Applications/Utilities folder, and then double-click Terminal.

  3. Enter the following command, and then press Return:

 

rm -r ~/Library/Application\ Support/Microsoft/Teams

 

  • Restart Teams.

New Teams

  1. If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command (⌘)-Q.

  2. In the Finder, open the /Applications/Utilities folder, and then double-click Terminal.

  3. Enter the following commands, and press Return after each command:

 

rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams
rm -rf ~/Library/Containers/com.microsoft.teams2

5. Restart Teams.

Have same issue. MS teams keeps writing to Downloads/MSTeams on each call leaving bunch of CompositorOutput_***.yuv files that have to be cleaned up manually
