MKEXTUNPACK(8) BSD System Manager's Manual MKEXTUNPACK(8) NAME
mkextunpack -- extract or list the contents of a multikext (mkext) archive SYNOPSIS
mkextunpack [-v] [-a arch] [-d output_directory] mkext_file DESCRIPTION
The mkextunpack program lists the contents of a multikext file, mkext_file, or unarchives the contents into output_directory (which must exist). The -v option causes mkextunpack to print the name if each kext as it finds them. DIAGNOSTICS
mkextunpack exits with a zero status upon success. Upon failure, it prints an error message and exits with a nonzero status. With a nonsegreated format 1 mkext file, wherein each kext may contain a universal binary, mkextunpack simply unpacks the contents. With an mkext file segregated by architecture (that is, with distinct internal archives of architecture-specific kexts), mkextunpack attempts by default to unpack or list kexts for the current machine's architecture. To choose a particular architecture to extract or list, use the -a option. There is no simple way to unpack a segregated mkext file into a set of kexts with universal binaries, but you can unpack each of its compo- nent architectures to separate directories for examination.

kextcache(8) BUGS
Many single-letter options are inconsistent in meaning with (or directly contradictory to) the same letter options in other kext tools. For version 1 mkext files, note that the file format doesn't record the original filenames of the kexts, so mkextunpack has to guess at what they are. It does this by using the value of the CFBundleExecutable property of the kext's info dictionary (Project Builder sets this to the base name of the kext bundle by default, but the developer can change it). If that property doesn't exist, the last component of the CFBundleIdentifier is used. Duplicates have an incrementing index appended to the name. Kexts that have no CFBundleExecutable or CFBundleI- dentifier property are named ``NameUnknown-n.kext'', where n is a number. Darwin March 6, 2009 Darwin

KEXTUNLOAD(8) BSD System Manager's Manual KEXTUNLOAD(8) NAME
kextunload -- terminate driver I/O Kit driver instances and unload kernel extensions (kexts) SYNOPSIS
kextunload [options] [--] [kext ...] DESCRIPTION
The kextunload program is used to terminate and unregister I/O Kit objects associated with a kernel extension (kext) and to unload the code and personalities for that kext. kextunload must run with superuser privileges. If another loaded kext has a dependency on the kext being unloaded, the unload will fail. You can determine whether a kext has dependents using the kextstat(8) tool. kextunload is a formal interface for unloading kexts in the Darwin OS and in Mac OS X. Software and installers can rely on its presence and invoke it in order to unload kexts. Note that long options are present as of Mac OS X 10.6 (Snow Leopard). The arguments and options are: kext Unload the loaded kext whose bundle identifier matches the CFBundleIdentifier of kext. All instances of IOService subclasses defined by the loaded kext and in the IOService plane of the I/O Registry are terminated; the kext is checked to make sure no instances of its libkern C++ classes remain; the kext's C++ static destructores and module stop routine are invoked; then the kext's executable and IOKitPersonalities are unloaded from the kernel. Failure at any stage prevents kext unload. -b identifier, -bundle-id identifier Unload executable and IOKitPersonalities (as described immediately above) for the kext whose CFBundleIdentifier is identifier. -c classname, -class classname Terminate all instances of class classname that are in the IOService plane of the I/O Registry, if possible, but do not unload the defining kext or its IOKitPersonalities. New load requests for devices that were driven by these terminated instances may result in the same class being instantiated at any time. -h, -help Print a help message describing each option flag and exit with a success result, regardless of any other options on the command line. -m identifier Same as -b (remains for backward compatibility). -p, -personalities-only Terminate services and remove personalities only; do not unload kexts. -q, -quiet Quiet mode; print no informational or error messages. -v [0-6 | 0x####], -verbose [0-6 | 0x####] Verbose mode; print information about program operation. Higher levels of verbosity include all lower levels. By default kextunload prints only warnings and errors. You can specify a level from 0-6, or a hexadecimal log specification (as described in kext_logging(8)). The levels of verbose output are: 0 Print only errors (that is, suppress warnings); see also -quiet. 1 (or none) Print basic information about program operation. 2 Prints information about unload stages. 3 Prints information about removal of personalities. 4 Prints information about module stop functions and C++ class destruction. 5 Prints detailed information internal operations such as bookkeping. 6 Identical to level 5 for kextunload. Unlike in other kext tools, the -verbose flag in kextunload applies to all kexts (that is, it turns on hexadecimal bit 0x8 by default). See kext_logging(8) for more information on verbose logging. DIAGNOSTICS
kextunload exits with a zero status upon success, or prints an error message and exits with a nonzero status upon failure. BUGS
