Codex adds locked computer use for Mac

This update significantly advances the capabilities of autonomous coding agents by enabling true background execution across devices without compromising local security. Deep integration with macOS via an Apple authorization plug-in avoids the fragility of traditional UI automation workarounds. The narrow scope of the unlock flow highlights the strict security boundaries required when granting LLMs root-level access to a machine. This positions Codex as an always-available background worker, allowing developers to safely kick off long-running tasks from their phones.
