OpenAI is updating its Codex desktop app for macOS with “Computer Use,” adding the ability to run tasks remotely from a phone even when the Mac screen is off and locked. OpenAI Developers say users can send Codex requests to operate apps on their Mac; a reported overlay on a locked Mac indicates “Codex is using your Mac” and prompts the user to unlock before interaction can proceed. The feature requires installing the Computer Use plugin and granting permissions, including Screen Recording and Accessibility, so Codex can click through windows, type, navigate menus, and interact with the clipboard in apps the user allows. OpenAI says Codex requests permission before operating each new app, and users can optionally mark specific apps as “Always allow.” The company also limits what the agent can automate, stating it does not automate Terminal apps, Codex itself, or system-level admin prompts. OpenAI says the capability is not available at launch in the European Economic Area, the UK, and Switzerland.
