OpenAI security and pressure

OpenAI is forcing macOS users to update ChatGPT and other desktop apps after a flaw in its software-signing pipeline exposed the company to fake-app risk. (openai.com) The company said on April 10 that a GitHub Actions workflow in its macOS app-signing process downloaded a malicious version of the developer library Axios on March 31, 2026. That workflow had access to the certificate and notarization material used to sign ChatGPT Desktop, Codex, Codex Command Line Interface, and Atlas for Apple computers. (openai.com) A signing certificate is the digital stamp that tells a Mac an app really came from the named developer. OpenAI said its investigation found no evidence that user data, systems, intellectual property, passwords, application programming interface keys, or released software were compromised or altered. (openai.com) (cnbc.com) OpenAI is still revoking and rotating the certificate, and it said older macOS app versions will stop receiving updates or support on May 8, 2026 and may stop working. The earliest supported builds signed with the new certificate are ChatGPT Desktop 1.2026.051, Codex App 26.406.40811, Codex Command Line Interface 0.119.0, and Atlas 1.2026.84.2. (openai.com) The episode lands as OpenAI is also fighting a legal battle with co-founder Elon Musk. In a filing reported April 10, OpenAI said Musk changed what he wants from the case weeks before trial, calling it a “legal ambush” and saying the shift would require different evidence and witnesses. (bloomberg.com) Bloomberg reported that Musk’s revised demands include sending any money won at trial back to OpenAI, unwinding OpenAI’s conversion, overseeing future financings and transactions, and removing Sam Altman as chief executive and board member. OpenAI and Microsoft deny Musk’s claims, and jury selection is scheduled to begin on April 27 in federal court in Northern California. (bloomberg.com) (cnbc.com) OpenAI had already escalated that fight on April 6, when it asked the California and Delaware attorneys general to investigate what it called Musk’s “improper and anti-competitive behavior.” In that letter, OpenAI strategy chief Jason Kwon said Musk had tried to undermine the company through attacks tied to the upcoming trial. (cnbc.com) The pressure has also turned physical. San Francisco police arrested a 20-year-old man on April 10 after a Molotov cocktail hit an exterior gate at Altman’s home around 4 a.m., and officers later found the same suspect at OpenAI’s headquarters after what police described as threats to burn down the building. (cnbc.com) (abcnews.go.com) OpenAI said no one was hurt in the attack and that it was assisting law enforcement. For now, the company’s immediate order is simpler than the rest of its problems: Mac users need current apps, and OpenAI needs the next two weeks to pass without another surprise.
