"Big Sur brings with it some really big visual changes, but also major changes under the hood. For instance, Apple has been progressively deprecating 3rd party Kernel Extensions or 'kexts' which Fusion needs to run VMs and containers. In order to continue to operate in this model, we’ve re-architected our hypervisor stack to leverage Apple’s native hypervisor APIs, allowing us to run VMs without any kernel extensions. On macOS Catalina systems, Fusion operates as it always has using kernel extensions to provide functionality. However on Big Sur systems, Fusion operates entirely without kexts."
