Is ChatGPT malware or safe to use on my Mac?

There have been some incidents involving a Mac telling a user that the ChatGPT app is malware and moving it to the trash. Overall, ChatGPT isn’t malware, and there’s a very easy fix.

This is not Apple making a judgement on the value of the ChatGPT app on the Mac, it’s macOS doing its job. Since 2022, macOS has included Xprotect, a feature you never usually need to know about, but which safeguards the Mac against malware.

In this case, as reported by users worldwide on social media, Xprotect had concluded that the ChatGPT app contained malware. Therefore the whole app is suspect, therefore macOS moves it to the Trash and won’t launch it.

There is nothing wrong with ChatGPT and it will not have installed malware on users’ Macs. To continue using it, the simplest way is to reinstall ChatGPT directly from the developer.

Apple’s Xprotect warning was legit, though, because of how it decides apps are legitimate, and how OpenAI changed that proof for both ChatGPT and ChatGPT Atlas. Apps are notarized through a certificate that shows they are legitimate, but OpenAI switched to a new certificate because of security concerns.

“We recently identified a security issue involving a third-party developer tool, Axios, that was part of a widely reported, broader industry incident,” wrote OpenAI in a blog post. “Out of an abundance of caution we are taking steps to protect the process that certifies our macOS applications are legitimate OpenAI apps.”

The company stresses that it found no evidence of the apps being altered, or user data accessed. It did also notifications via its apps that users should update urgently by May 8, 2026.

But for those users who did not, their copies of ChatGPT and ChatGPT Atlas are no longer notarized so the Mac will not run them. It’s inconvenient having to redownload the apps, but if OpenAI had not done this, bad actors could conceivably have created what would entirely appear to be legitimate ChatGPT apps.

Then, too, if Xprotect didn’t work the way it does, there would still be no way to prevent such malware from actually being installed on Macs.
