Patna: OpenAI has asked users of its Mac apps to update their software immediately after discovering a security issue linked to how its applications are signed and verified. The company said the problem does not show any sign of user data being stolen or any direct breach of its systems. However, it is still taking strong safety steps to prevent any possible risk in the future. The warning mainly affects users of macOS apps made by OpenAI.
The issue began with a popular developer tool called Axios, which was affected by a supply-chain attack. This type of attack happens when hackers try to insert harmful code into tools that are widely used by developers. OpenAI said that on 31 March 2026, a harmful version of Axios was downloaded during an internal automated process used to sign Mac applications. This process is important because it helps confirm that apps are real and safe to use.
OpenAI explained that the system involved had access to important security certificates used to sign its apps. These certificates are like digital IDs that tell computers and users that the software is genuine. Even though the company believes the attacker probably did not manage to steal these certificates, it is treating the situation very seriously. As a result, OpenAI has decided to replace the old certificates with new ones as a safety measure.
The company is working with security experts and also with Apple to make sure old versions of the apps cannot be reused or trusted again. OpenAI has already released updated versions of its Mac apps, including ChatGPT Desktop, Codex, Codex CLI, and Atlas. These updated apps use new security certificates.
From May 8, older versions of these apps will stop working properly and will not receive any further updates. OpenAI is strongly advising all users to upgrade as soon as possible to avoid interruptions. The company said this step is necessary to keep its apps secure and protect users from possible future attacks on software development tools.
