Transitioning your kernel extensionsĬertain kernel extensions are unsupported on macOS Big Sur. Starting with macOS Big Sur, macOS releases no longer load kernel extensions that use deprecated kernel programming interfaces (KPIs) by default. As part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods, kernel extensions have been deprecated.

System extensions on macOS Catalina 10.15 or later allow software, such as network extensions and endpoint security solutions, to extend the functionality of macOS without requiring kernel-level access. Deprecated Kernel Extensions and System Extension Alternatives
