  • •macOS flagged the ChatGPT app as malware due to revoked security certificates.
  • •Users are advised to reinstall the app from official sources to restore functionality.
  • •A fake download site is distributing malware disguised as ChatGPT installers.

Mac users reported that the ChatGPT desktop app was flagged as malware by macOS's Xprotect system, which moved the app to the Trash. This issue arose after OpenAI revoked security certificates for older app versions due to a third-party security incident involving the developer tool Axios. Users were advised to reinstall or update the app from official sources to restore notarization. Malwarebytes also reported a related threat from a fake download site distributing malware disguised as ChatGPT installers. The fake site, openew[.]app, delivers Windows credential stealers and a macOS strain named Odyssey Stealer. OpenAI confirmed the certificate change and advised users to update their apps to avoid issues. The situation highlights both false-positive malware flags and real malware risks for users.
