Summary
Enabling Settings → Computer use → Locked use immediately turns the setting back off and displays the following error:
Unable to update “Locked use” setting.
The regular Google Chrome and Microsoft Excel controls can be enabled successfully.
Environment
- Codex App: 26.814.41957 (6744)
- macOS: 14.8.5
- Kernel/architecture: Darwin 23.6.0, Intel x86_64
- MDM enrollment: No
Steps to reproduce
- Open the Codex/ChatGPT desktop app.
- Go to Settings → Computer use.
- Enable Locked use.
- Observe that the toggle returns to the disabled state and an error message appears.
Expected behavior
Locked use should be enabled, and the required macOS authorization component should be installed and started.
Actual behavior
The setting is not saved, and no managed Computer Use service is started.
Diagnostics
The Codex desktop log reports:
Failed to reconcile managed Computer Use service: Failed to spawn managed Computer Use service
The macOS unified log reports:
AMFI: constraint violation: sky.node has entitlements but is not a main binary
It also reports that the following application-group entitlement is ignored:
2DC432GLL2.com.openai.sky.CUAService
An XPC bootstrap lookup subsequently fails with:
No such process
The main application and sky.node both pass code-signature verification, and the application is notarized. No corresponding managed Computer Use service process is running.
Additional context
This appears to be a packaging or compatibility issue affecting the native Computer Use component on Intel macOS Sonoma. The failure happens while spawning the managed Computer Use service, before the Locked use setting can be enabled.
