macOS Webcam Not Detected in Teams/Zoom After Permission Reset

- Meeting apps cannot access camera after settings or OS changes. - Camera works in one app but not another. - Camera permission prompt no longer appears when expected.

- TCC privacy entry missing, stale, or managed by profile. - App path/signature changed after update and old permission no longer applies. - External camera enumeration conflict through dock/hub path.

Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.

Confirm the user is signed in with the correct corporate account, system time is accurate, network/VPN connectivity is stable, and the application is not running in offline or limited mode.

Use the command snippets below to collect non-destructive diagnostics. Capture output in the ticket when escalation may be required. Avoid deleting profiles, cached credentials, or managed app data unless the runbook or admin approval explicitly allows it.

- Review Privacy & Security camera permissions for affected apps. - Fully quit/relaunch app after permission changes and retest. - Test built-in camera vs external USB camera to isolate hardware path. - Escalate TCC/profile remediation through managed endpoint process.
