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.
- -bidentifier,- -bundle-ididentifier
- Display the status of only the kext with the given bundle identifier. This
      option trumps the -no-kerneloption; 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.
