For work I use the communication platform MS Teams, which makes having a webcam kind of mandatory. Since I used to work with my laptop in clamshell mode, I wasn’t able to use the internal webcam. That’s when I discovered EpocCam, a software, which makes it possible to use a smartphone as webcam. Using your smartphone is not only pretty convenient but has also very good quality when compared with a standard webcam.
At some point MS Teams stopped recognizing EpocCam after an update. After a quick web search I found a thread with a solution. Unfortunately I have to apply this solution every time I update MS Teams, but at least it works.
Here is the solution:
sudo codesign --remove-signature "/Applications/Microsoft Teams.app"
sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper.app"
sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (GPU).app"
sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Plugin).app"
sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Renderer).app"
Use these commands in the terminal when MS Teams is closed. The next time it starts up you have to give some permissions again, which is quite inconvenient.
