Hi, thank you again. We were unable to reproduce this on our end with Xcode 26.4.1 and Codex 0.129.0-alpha.9, so it may be something specific to your configuration. Could you navigate to Xcode Settings → Components → Other Components → Codex and check the version listed there? It should read 0.129.0-alpha.9. If it shows a different version or indicates an update is available, try deleting it and redownloading the agent executable, then attempt signing in again. Let us know if that resolves the issue or if you're still seeing the login loop afterward, and we can dig deeper from there.
