macOS Catalina Legacy System

I have been informed that macOS Catalina will be the last macOS to fully support legacy system extensions. Thus, please advise whether an updated version of the software is available or planned. Also, does the extension need to be remove or disable? If so, how will this affect my system.

You have to check with the legacy system extension's developer. Click the Learn More... button accompanying that message.


Excerpt:


"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."
