macOS camera works in Zoom but not Teams

Scenario

The built-in camera functions in one app but appears unavailable or black in Microsoft Teams on macOS.

Review macOS privacy permissions for camera access per application.
Check whether a virtual camera plugin or recent app update changed device selection.
Test in the Teams web app to separate local app issues from broader permissions.
If security tooling is involved, capture its prompts or logs before reinstalling collaboration apps.

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
