Legacy system extensions and the apps that rely on them continue to work today. But now is a good time to contact the developer to learn whether an updated version of their software is available or planned.

The developer can also explain how to remove or disable the extension, and the consequences of doing so. Information about products not manufactured by Apple, or independent websites not controlled or tested by Apple, is provided without recommendation or endorsement.

Apple makes a better job of explaining things in a knowledge base articledescribing system extensions as follows:.

System extensions are a category of software that works in the background to extend the functionality of your Mac. Your Mac identifies these as legacy system extensions. Or to put it another way, an app you are using has its tentacles in the underpinnings of how macOS works via a kernel extension. The outcome will be a more secure macOS which, we can all agree, is only a good thing for users. If the app has been updated by the developer, often simply installing that available update will resolve the issue by removing the dependency on the kernel extension.

If the app that the message mentions is no longer in development, things get trickier. The option of not updating to future macOS version remains, but it may be better to look at alternative apps rather than going that route, particularly if you want to take advantage of new features available in upcoming macOS releases.

In the meantime, you may continue to see that error message, and you will see it until the mentioned app is updated or removed from the Mac. For now, make sure to disable automatic software updates to avoid accidentally installing something, and instead you may want to manually install specific macOS updates for a while too. Have you seen this error message with a particular Mac app? Did you update the app and resolve the issue, or did you find another solution?
