OpenAI Breach: Update ChatGPT Mac Apps by June 12

OpenAI is requiring Mac users to update ChatGPT and other desktop apps soon. This follows a supply chain attack that exposed signing certificates Apple uses to verify software. The company disclosed the incident on May 13th. Malware from a "Mini Shai-Hulud" attack infected two employee devices. Investigators found unauthorized access in a limited set of internal source code repositories linked to these employees. OpenAI rotated its signing certificates and re-signed affected apps. They found no evidence that customer data, production systems, or intellectual property were compromised. Apple's macOS security will block apps signed with older certificates after June 12th. This makes the update mandatory for affected Mac users. Specific affected versions include ChatGPT Desktop 1.2026.125, Codex App 26.506.31421, Codex CLI 0.130.0, and Atlas 1.2026.119.1. You need to update your apps to ensure they continue to function and receive updates.
