Repeated macOS Permission Prompts with GodotSteam or a Custom Godot Build

These are the steps I used for repeated permission prompts with a locally installed GodotSteam build on macOS.

First, reset the relevant privacy permissions. Use the bundle identifier of your build; the command below uses Godot's identifier:

tccutil reset All org.godotengine.godot

Then open System Settings → Privacy & Security → Full Disk Access, click +, and add GodotSteam (or your custom Godot build).

Finally, apply an ad-hoc signature to the app bundle. Replace the path with the location of your app; mine is in /Applications:

codesign --force --deep --sign - /Applications/GodotSteam.app
