kmutil is a multipurpose tool for managing kernel extensions (kexts) and kext collections on disk. It takes a subcommand and a number of options, some of which are common to multiple commands. kmutil interacts with the KernelManagement subsystem for loading, unloading, and diagnosing kexts. It can also be used for inspecting the contents of a kext collection, interacting with the kernel to query load information, finding kexts and kext dependencies on disk, creating new collections of kexts, and displaying other diagnostic information.
