pfix v2.4 Released

This version is now deprecated, consult the downloads page for a link to the latest version.



  • – When running under OS X 10.6.x pfix now tests to see if kextd is running, if so it touches /S/L/E instead of rebuilding system caches with kextcache. This significantly reduces execution time.
  • – Repairing permissions with diskutil is now optional.
  • – Minor improvements to terminal output.


  • -If target is a mounted volume execute command to enable permissions on the volume prior to running pfix.


  • -A number of alterations/additions were made to enable proper functionality of pfix when it is launched from a USB Installer or Installation DVD.

  • -pfix version info now displayed in terminal before running any operations.
