Troubleshoot a Codex theme on macOS

Resolve permissions, application identity, image payload, launchd state, and verification problems without modifying Codex.app.

Platform behavior can change. Compare this guide with the original repository at commit 26c6c410e0e0.
01Restore and open stock Codex
02Run the upstream tests
03Validate the image theme directory
04Reinstall and verify the current process

Separate macOS permissions from theme logic

If a .command launcher will not open, inspect the Finder security prompt and file execute permission for the reviewed original repository. Do not disable Gatekeeper globally. Confirm the official Codex application has launched once and its expected configuration path exists.

Validate the payload and signed runtime

The upstream macOS flow validates the Codex application, Team ID, architecture, and bundled Node before use. An explicit theme directory must contain a valid theme.json and prepared image. The current upstream commit intentionally fails instead of silently falling back to demo assets when that file is missing.

Clean state through Restore

Use the documented restore launcher or script to stop only the matching injector state. Reopen Codex normally, then reinstall from the current original source. Verify Home, a normal Task, Diff, composer, menus, and route changes; check that a reload does not leave stale styling.

Never fix a theme by altering the Codex.app bundle, app.asar, code signature, API keys, or model provider settings.
