NAME

kextstat — display status of loaded kernel extensions (kexts)

kextstat [-a] [-h] [-k] [-l] [-b identifier] ...

The kextstat utility has been deprecated. Please use the kmutil(8) equivalent: kmutil showloaded.

The kextstat utility displays the status of any kexts currently loaded in the kernel. The following information is shown for each loaded kext:

Index: The load index of the kext (used to track linkage references). Gaps in the list indicate kexts that have been unloaded.
Refs: The number of references to this kext by others. If nonzero, the kext cannot be unloaded.
Address: The address in kernel space where the kext has been loaded.
Size: The number of bytes of kernel memory that the kext occupies. If this is zero, the kext is a built-in part of the kernel that has a record as a kext for resolving dependencies among kexts.
Wired: The number of wired bytes of kernel memory that the kext occupies.
Architecture (if the -a option is used): The architecture of the kext.
Name: The CFBundleIdentifier of the kext.
(Version): The CFBundleVersion of the kext.
<Linked Against>: The index numbers of all other kexts that this kext has a reference to.

These options are available:

-a, -arch: Print the architecture of the kext.
-b identifier, -bundle-id identifier: Display the status of only the kext with the given bundle identifier. This option trumps the -no-kernel option; if both are given and a kernel component is specified, its information is shown.
-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.
-k, -no-kernel: Don't show information for built-in components of the kernel.
-l, -list-only: Print the list of loaded kexts only and omit the header (useful for running output through text-analysis tools).
-s, -sort: Sort the list by load address.

The kextstat utility exits with a status of 0 on success and with a nonzero status if an error occurs.
