OpenAI is telling macOS users to update its desktop apps after a security problem hit a third-party tool used in the apps’ certification chain. (openai.com) On April 10, OpenAI said the issue involved Axios, a developer library tied to a broader industry incident, and said it found no evidence that user data, internal systems, or intellectual property were accessed. (openai.com) (reuters.com) The company said it is revoking and rotating the digital certificates that macOS uses to verify an app really comes from the named developer. OpenAI said users need the latest versions of ChatGPT Desktop, Codex App, Codex Command Line Interface, and Atlas. (openai.com) (forbes.com) A developer certificate on a Mac works like an ID badge at a secure door: the operating system checks the signature before it trusts the software. OpenAI said it is changing those credentials to reduce the risk that fake apps could appear legitimate. (openai.com) (cnbc.com) The warning is limited to macOS because the affected process was the one that certifies OpenAI’s Mac applications. OpenAI’s help documentation says the Team ID stays the same, but some allowlist checks based on organization name or certificate fingerprint must be updated. (openai.com 1) (openai.com 2) OpenAI said older Mac app versions will stop being supported after May 8, 2026, if users do not install updates. That deadline matters for companies that manage approved software lists or device fleets and may need to change security policies before users can launch the apps normally. (forbes.com) (openai.com) Reuters, CNBC, and OpenAI all said the company framed the move as a precaution after a supply-chain style incident, not as a confirmed breach of customer accounts or chats. OpenAI said it took the step “out of an abundance of caution” while protecting the process that proves its Mac apps are authentic. (reuters.com) (cnbc.com) (openai.com) For Mac users, the practical message is narrow and immediate: update OpenAI’s desktop apps before May 8 or expect older versions to lose support as the company replaces the credentials behind them.
