Direct answer
A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. For macOS app privacy permissions, first inspect Privacy & Security and test the app immediately after granting one permission.
What this covers
- macOS app privacy permissions with this exact failure state
- Diagnosis across system permission versus app selection, managed policy and relaunch requirement
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord whether the feature is absent, disabled, powered but unresponsive, or showing a message. Expected behavior: grant the selected app only the camera, microphone, files, accessibility or screen access it needs.
Isolate the component boundary
ReversibleInspect Privacy & Security and test the app immediately after granting one permission. Test the simplest supported configuration with unrelated accessories and optional services removed. Boundary to separate: system permission versus app selection, managed policy and relaunch requirement.
Correct only the proven cause
ReversibleGrant the narrow permission and relaunch/update the app. Restore only the failed prerequisite or path; do not change working layers.
Verify and stop safely
ReversibleRepeat from a cold start and complete one normal use. Do not grant Full Disk Access or Accessibility to an untrusted app.

Common follow-ups
What should I check first when macOS app privacy permissions has this problem?+
Inspect Privacy & Security and test the app immediately after granting one permission.
Why not factory-reset immediately?+
The useful boundary is system permission versus app selection, managed policy and relaunch requirement. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not grant Full Disk Access or Accessibility to an untrusted app.
