Diagnose and fix macOS permission problems for automation - Accessibility, Screen Recording, Automation/Apple Events, Full Disk Access, TCC. Use when a Mac automation fails silently, when the user gets "not authorized" errors, when setting up Mac control for the first time, or when something worked before and stopped.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# macOS permissions Almost every "my Mac automation broke" is one of five things. Work through them in order. ## 1. Check state ```bash chewie doctor ``` Reports each grant, names the exact app that needs it, and lists which tools are on PATH. ## 2. You cannot grant these from code Believe this before you spend an hour on it. - `tccutil` **only resets**. There is no `tccutil grant`. - The TCC database is SIP-protected. Editing it does not work. - The only programmatic grant is an **MDM PPPC profile**, requiring an enrolled machine. Everything else is a human clicking a toggle. Design around that instead of fighting it. ## 3. Grant it to the right app **The app hosting the agent, not the agent, and not the CLI.** A CLI binary has no bundle identity, so macOS attributes its requests up the responsibility chain to whatever `.app` launched it. Consequences that confuse people: - The prompt says "Cursor wants to control Finder" when it was your script - It works in Terminal and silently fails in VS Code, because grants are per host - Two different tools launched by the same terminal share one grant `chewie doctor` resolves the outermost `.app` and prints its name. …

How to install
mdr add calebnewtonusc/chewbacca/mac-permissions@sha256:0e65bf5a57742a67The line at the top of this page pins the label git:20260904.ee0eb1b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
