Classify the prompt before acting
Not every macOS failure is the same permission problem. A file can lack its executable bit, carry a browser quarantine attribute, be blocked because its developer cannot be verified, fail because Finder and Terminal use different PATH values, request access to a selected image, or target an unsupported architecture. Copy the complete message and identify whether it comes from Finder, Terminal, System Settings, the shell, or the script itself. Note the exact .command file or script. Avoid broad advice such as allow everything; the safest solution depends on the precise layer that refused the action.
- Capture the full message and source application.
- Name the exact launcher or script.
- Note Apple Silicon or Intel.
- Separate operating-system prompts from script errors.
Verify provenance before using Open Anyway
A system-provided Open Anyway action does not verify that a download is safe. Return to the original repository, confirm owner and macOS directory, inspect the launcher and the script it calls, and review recent history. Compare any downloaded archive or files with the source method documented there. Do not follow a mirror that instructs you to disable Gatekeeper globally or paste an opaque command with elevated privileges. If the reviewed source does not explain why a permission is needed, stop. Keep the original Codex application in its normal signed location; the visual workflow should not require replacing or modifying it.
- Use the verified original repository.
- Read launcher and called script together.
- Reject global security-disable instructions.
- Keep official Codex signed and unmodified.
Grant only narrow, explained access
The customization flow may need the file you explicitly choose, and launchers need permission to execute. That does not imply a need for Full Disk Access, contacts, microphone, camera, broad accessibility control, or permanent administrator rights. When macOS offers a file-specific or application-specific decision, prefer it over weakening system-wide protection. Do not recursively make every downloaded file executable or remove quarantine from an entire home directory. If an organization manages your Mac, follow its policy and ask an administrator rather than bypassing controls. Record the narrow change you made so it can be reviewed or reversed later.
- Prefer file-specific approval.
- Avoid unrelated privacy permissions.
- Do not modify whole directory trees.
- Follow managed-device policy.
Compare Finder and Terminal behavior carefully
A .command launcher opened from Finder can use a different working directory and environment from a shell in Terminal. If it closes immediately, run only the reviewed underlying script from its documented directory so output remains visible. A command-not-found result can be a PATH issue; a permission-denied result can be an executable or directory issue; a bad-CPU-type result points toward architecture. Do not treat all three by adding sudo. The upstream macOS workflow states that a separate global Node.js installation is not required, so an unexpected runtime download request should be investigated rather than accepted automatically.
- Run the reviewed script from its documented directory.
- Read the exact shell error category.
- Do not use sudo as a universal fix.
- Check architecture and inherited PATH separately.
Separate selected-image access from launcher security
If installation and launch succeed but image selection fails, test a copy of a modest, rights-cleared PNG or JPEG in a location you can normally read. This protects the original and helps isolate format, size, cloud-placeholder, and file-access behavior. Follow documented limits and avoid moving sensitive personal photos into public or shared folders merely to bypass a prompt. If Finder grants the selected file but processing fails, save the script output and check whether the prepared asset was created where the source documents expect it. Image failure does not justify broader application or disk access.
- Use a non-sensitive test copy.
- Check format, size, and local availability.
- Keep private images out of public folders.
- Preserve sanitized processing output.
Restore, verify, and report without weakening security
After changing one narrow permission or correcting one source issue, relaunch from a clean state and run the documented Verify or doctor workflow. Check official Codex, home and task views, and image selection. Exercise Restore and confirm normal appearance returns. If the problem persists, report Mac model family, Apple Silicon or Intel, macOS version, source commit, exact launcher, complete sanitized error, and the narrow permissions already tried. Remove usernames, home paths, account details, and private image names. Do not report a workaround that disables system protection as a solution; report the underlying prompt and reproducible path instead. State whether the reviewed script behaves differently from Finder and Terminal, because that comparison separates inherited environment problems from file approval or architecture.
- Verify after one change at a time.
- Confirm restore and official-app baseline.
- Report architecture and exact prompt.
- Keep security protections enabled.
