ChatGPT's Major Update: Support for Older Mac Devices to End—Is Your Mac on This List?
OpenAI has issued an important update advisory for macOS users. The company has explicitly stated that, effective May 8, 2026, older versions of applications such as ChatGPT Desktop, Codex, Codex CLI, and Atlas will cease to function. This decision was made in response to a security vulnerability, with the aim of enhancing user safety.
**Why are the apps being discontinued?**
The root cause of this issue lies in a JavaScript library named Axios. According to reports, certain versions of this library were compromised after a hacker infiltrated the system and injected malicious code. However, these compromised versions were available for only a brief period before being removed. OpenAI states that, to date, there is no evidence suggesting that user data or the company's internal systems have been compromised; nevertheless, the company has taken necessary precautionary measures to ensure security.
**What changes have been implemented, and what will be the impact?**
OpenAI has updated (rotated) its code-signing certificates for macOS. This means that applications built using the older certificates will no longer be recognized as valid by the system. Consequently, apps running on older versions may stop launching or functioning after May 8. This measure serves as a means to further bolster security and mitigate potential threats.
**How can you determine if you will be affected?**
If you use ChatGPT Desktop, Codex, or other related applications on a Mac, you should immediately verify whether your app is running on the latest version. If you have not updated the app in a significant amount of time—or if you installed it prior to the release of the relevant security updates—there is a strong possibility that it will cease to function after May 8. You can check for updates within the app's settings or visit OpenAI's official website to cross-reference your version with the latest release.
**What should you do before May 8?**
To avoid being affected by this issue, you simply need to take one straightforward step: immediately update all your relevant applications. OpenAI has advised users to download the latest versions of these applications directly from the company's official announcements page. Doing so will ensure that your app functions correctly with the new certificates, and you will not encounter any interruptions.
Are any other changes required?
The company has also clarified that users do not need to change their passwords or update their API keys. This change applies only to macOS users. Apps running on iOS, Android, and Windows will not be affected by this change.
