OpenAI Codex Develops New Capability for Background Operation During Mac Lock Screen
OpenAI is developing a new feature for Codex aimed at allowing AI to continue operating software, running tests, and processing tasks in the background even when the Mac is locked or in sleep mode, breaking the current hard limitation that desktop AI must keep the screen unlocked.
Previously, interface control tools including Codex and Claude Code required the computer to be unlocked to view the screen and simulate mouse and keyboard operations. The new feature supports users to remotely control their home Mac using their phone while on the go, without needing to physically unlock the screen.
OpenAI is also testing cross-device connectivity, allowing the main device to remotely control a Mac Mini running Codex. This underlying attempt may challenge macOS security defenses and could lead to future intervention from Apple.

OpenAI has repeatedly expanded Codex's capabilities from code completion to agent execution since its launch. This new background operation during lock screen development continues its path of transforming AI from an "assistive tool" to an "autonomous worker." The earlier desktop version already integrated screen control, and this move is a key step in further eliminating physical constraints.
On the capital path, OpenAI is investing engineering resources into system-level permissions and cross-device protocols, combined with the ChatGPT App's remote invocation. The motivation is to seize the developer "always-on agent" scenario by enhancing daily active users and paid conversions through the removal of lock screen barriers, while also accumulating foundational capabilities for future personal AI employee products.
Similar to the ongoing iterations of Cursor and GitHub Copilot in desktop control, and Apple's own cautious management of system permissions with Apple Intelligence, OpenAI Codex is currently in an early radical phase of transitioning desktop agents from "screen dependency" to "interface-less persistent operation."
Essentially, this represents a technological substitution: traditional desktop AI is highly constrained by operating system security boundaries and user physical states. The lock screen background capability allows AI to achieve true 24/7 autonomous execution by bypassing these constraints, removing the requirement for humans to be present to unlock, and mechanically pushing developer tools from cloud-based dialogues to local persistent agents, shifting pricing power from operating system vendors to AI platforms.

Locking the screen is not security; it is the last barrier humans have against AI.
For AI to work for you, it must be able to operate even when you are not present.
The cost of bypassing the lock screen may be the transfer of control over the entire ecosystem.
