Conversely, if an approval is revoked, the system extension is unloaded and marked for removal on the next restart of the Mac.Every now and then it is necessary to disable the System Integrity Protection, or SIP, security feature available in macOS. For example, if an extension is pending approval and a configuration profile is pushed that allows the extension, the extension is allowed to load. In macOS 11.3 through macOS 11.6.4, making changes to a system extension profile directly affects the state of an extension. Optionally, MDM can disallow users from approving their own system extensions from loading. System extensions support robust management using MDM, including the ability to allow all extensions from a specific developer or of a specific type (like network extensions) to load without user interaction. Even though kexts inherently have full access to the entire operating system, extensions running in user space are granted only the privileges necessary to perform their specified function. By running in user space, system extensions increase the stability and security of macOS. MacOS 10.15 or later enables developers to extend the capabilities of macOS by installing and managing system extensions that run in user space rather than at the kernel level.
