Guide:
If your camera isn’t working in Microsoft Teams on macOS, and terminal commands (like permissions fixes) return errors such as kill:9
, follow these steps to diagnose and resolve the issue.
Step 1: Confirm Camera Functionality
Test the Camera in Other Apps
Open FaceTime or Photo Booth to ensure the camera works system-wide.If it doesn’t work, there’s a macOS-level issue (e.g., hardware/driver problem).
If it works, the problem is specific to Teams.
Step 2: Check macOS Permissions
Grant Camera Access to Teams
Go to System Preferences > Security & Privacy > Privacy Tab > Camera.
Ensure Microsoft Teams is checked.
If Teams isn’t listed, proceed to Step 3.
Step 3: Reset Teams Permissions
Trigger a Permission Request
Quit Teams completely (right-click the Teams icon in the Dock > Quit).
Open Terminal and force-reset permissions:
tccutil reset Camera com.microsoft.teams
Relaunch Teams. It should now prompt for camera access. Click Allow.
Step 4: Fix Terminal Errors (e.g., "kill:9")
The kill:9
error occurs when a command tries to terminate a process that isn’t running or lacks permissions.
Avoid Force-Killing Teams
Instead of
kill -9
, use:pkill "Microsoft Teams"
This gracefully quits Teams. Relaunch it afterward.
Step 5: Update Software
Update Teams
Open Teams > Click your profile picture > Check for Updates.
Update macOS
Go to System Preferences > Software Update.
Step 6: Clear Teams Cache
Corrupted cache files can break permissions.
Delete Cache Folders
Quit Teams.
Run in Terminal:
rm -rf ~/Library/Application\ Support/Microsoft/Teams
Relaunch Teams and log in again.
Step 7: Test in a New User Account
Create a temporary macOS user account to rule out profile-specific issues:
System Preferences > Users & Groups > Add a New User.
Log in to the new account and test Teams.
Step 8: Use Teams Web Version (Workaround)
If the app still fails, use the browser version:
Go to Teams Web.
Ensure the browser (Chrome/Safari) has camera access in System Preferences > Security & Privacy > Camera.
Step 9: Advanced Fixes
Check for Conflicting Processes
In Terminal, run:
lsof | grep -i "Camera"
If another app is using the camera (e.g., Zoom), quit it.
Reset All Privacy Permissions
In Terminal:
tccutil reset All
(Note: This resets permissions for all apps.)
Troubleshooting Table
Symptom | Fix |
---|---|
Camera not listed | Reinstall Teams or trigger permission prompt (Step 3). |
"Kill:9" in Terminal | Use pkill instead of kill -9 (Step 4). |
Camera works elsewhere | Reset Teams cache (Step 6) or use the web version (Step 8). |
Final Notes
If the issue persists, contact Microsoft Support or check the Teams Community Forum.
For hardware-related camera failures, consider external USB webcams as a backup.

Teams camera issue
Am I the only one that cannot (for the life of me) get the camera to work on teams? I have followed every video I could find on setting the permissions and it will not show me the successful added in terminal. Just shows kill:9
