Description
On macOS Ventura/Sonoma, registering as a LaunchAgent triggers a system notification: "App Background Activity - hydraheadflatscreen can run in the background." This persists until a user physically clicks X and is distracting on an unmanned kiosk. The POST /api/v1/warnings/notifications/suppress suppresses the in-kiosk UI warning but cannot dismiss the macOS system banner. Options: (1) add LSBackgroundOnly or SMAppService registration to avoid the prompt, (2) auto-dismiss via AppleScript on first boot, (3) document as expected one-time behavior per machine lifetime.
