ChatGPT Blocked: macOS Flags App as Malicious

Apple users report that macOS is moving the ChatGPT program to the trash. The system marks it as malicious software and blocks its launch. Here's the thing: this isn't a security incident or an infection. The problem stems from changes in OpenAI's certification system. Apple's built-in security, XProtect, uses digital certificates to verify software. OpenAI urgently changed certificates for its macOS applications, including ChatGPT. What happened is, old versions of the ChatGPT client are no longer considered trusted by macOS. XProtect then perceives these outdated versions as potentially dangerous and blocks them. OpenAI confirms this certificate change was a preventive measure following a security incident involving a third-party tool. They emphasize no user data compromise or app changes were detected. OpenAI had actually warned users to update by May 8, 2026. Users who didn't update faced the lockout. The solution is simple: delete the old ChatGPT version and download the current client from the official OpenAI website. This ensures the program passes the XProtect check. This matters because it highlights the importance of keeping software updated for security and functionality.
