What issue are you seeing?

After enabling Computer Use for the Codex App, the macOS system experienced recurring high CPU usage and file descriptor (fd) exhaustion due to syspolicyd. During the failure, syspolicyd held approximately 2540 fds pointing to /Applications/Codex.app/Contents/MacOS/Codex and logged errors such as "Too many open files," "Failed to open main executable for hashing," "Failed to call driver: 0x3," and "SecStaticCode" failure. Subsequently, manually launching apps like Chrome and TikTok from the Dock/Finder resulted in continuous pop-ups but no opening. Disabling the Computer Use UI switch did not completely resolve the issue.

The following were found installed on this machine by Computer Use:

• /Library/Security/SecurityAgentPlugins/CodexComputerUseAuthorizationPlugin.bundle

• AuthorizationDB right: com.openai.sky.CUAService.AuthorizationPlugin.remote

• This right is referenced in the system.login.screensaver rule

• The com.openai.sky.CUAService Accessibility permission exists in TCC.

It is speculated that the system-level integration of Computer Use/locked-use triggers syspolicyd to repeatedly evaluate the Codex bundle in a specific macOS environment, eventually causing syspolicyd file descriptor exhaustion, which in turn affects the Gatekeeper startup evaluation of other apps.
