OpenAI launched a new 'Locked Use' feature for its Codex desktop agent on macOS. It allows the AI to perform tasks like UI operations and workflow automation even when the Mac is locked or the screen is off, moving beyond traditional 'screen-on' requirements. The feature, enabled via a specific plugin and user-granted permissions, aims to facilitate long-duration development tasks. It includes operational constraints and is initially unavailable in the EEA, UK, and Switzerland, raising new considerations for enterprise security and compliance.
