I met this issue. In my case, i was mistakenly install codex via npm.

Use which codex to confirm that you are using codex binary installed by homebrew others than npm.

If you are using npm unfortunately, just uninstall it by running:

npm uninstall -g @openai/codex @openai/codex-darwin-arm64

Now codex will point to the correct one.

which codex will return /opt/homebrew/bin/codex

@wongzigii Thank you for your feedback.

However, in my case, I installed the binary via JetBrains AI Assistant. I noticed that this error is appearing in the IDEs I have installed (Android Studio, RustRover, PyCharm, Goland, WebStorm, DataGrid).

This should be tied to OpenAI's recent macOS signing certificate rotation due to Axios supply chain incident. Update the latest version 1.130 and you should be fine. You probably have a very outdated build. Or in your case the jetbrains is pointing to an old one.

Yes, @Q-rm 's analysis is correct. You need to update to a more recent build.
