OpenAI Patches macOS Security Vulnerability Affecting Desktop Apps

OpenAI identified and patched a security issue in its macOS applications involving a third-party developer tool that could affect code signing certificates. The company confirmed that user passwords, API keys, and data were not accessed during the incident. All users must update their ChatGPT, Codex, and other OpenAI macOS apps by May 8, 2026, as older versions will no longer receive updates or support after this deadline. The security patch addresses certificate validation issues that could potentially allow unauthorized code execution on affected systems.
