OpenAI Issues Security Warning for Mac Users Running ChatGPT and Other Apps
OpenAI has alerted macOS users to update ChatGPT and related apps after a supply chain attack exposed a vulnerability, though user data remains safe and no password changes are required
Users running OpenAI applications on Apple desktops and laptops are being urged to take immediate action after the company disclosed a recent security concern affecting its macOS ecosystem. The warning specifically targets those using apps like ChatGPT Desktop and developer tools linked to OpenAI.
The issue came to light following a supply chain attack that targeted a third party tool used in the app verification process. OpenAI relies on automated systems to ensure its applications are authentic, but a compromised version of one such tool was inadvertently downloaded during the process, leading to the execution of malicious code.
Despite the breach, OpenAI has clarified that there is no evidence of user data exposure. Sensitive information including passwords and API keys remains unaffected, and the company confirmed that its internal systems and intellectual property were not compromised.
However, as a precautionary measure, OpenAI has begun rolling out updated security certificates across its macOS applications. Older certificates are being phased out to prevent any potential misuse, and users are being advised to install the latest updates without delay.
The impact is limited to macOS, meaning users on other platforms such as Windows, Linux and Android are not affected by this issue. Still, Mac users must ensure they are running the latest version of apps to avoid disruptions.
Several applications are part of the affected group, including ChatGPT Desktop, Codex App, Codex CLI and Atlas. Older versions of these apps will soon lose support and are expected to stop functioning entirely after early May 2026 if not updated.
OpenAI has emphasized that updates should only be performed through official channels or built in app mechanisms to avoid downloading counterfeit software. The company has also provided a transition window, allowing users time to safely upgrade to versions signed with the new certificates.
This incident highlights the growing risks associated with software supply chains, where even trusted development tools can become entry points for attackers. For users, the message is clear: keeping software up to date is no longer optional but essential for digital safety.
