Tiny Deathstars of Foulness

Deleting the contents of the /Library/Managed Preferences directory is definitely one way to refresh your managed preferences cache in Mac OS X, but there have been commands specifically designed to clear the cache for each version of Mac OS X. By OS, these include the following:

  • 10.6 – mcxrefresh – You can use this command (in /usr/bin) to refresh managed preferences
  • 10.6 also has a ManagedClient binary in /System/Library/CoreServices/ When run with a -f option, ManagedClient will force updates.
  • 10.5 has a binary called mcxd located in /System/Library/CoreServices/ which can also be run with a -f option
  • 10.4 has a binary called MCXCacher, stored in /System/Library/CoreServices/ which also supports the same -f option.

There are a number of other ways to go about this. If you have some that you use that I did not mention please feel free to add a comment.

    I asked for mcxrefresh to be made to compete against utilities like gpupdate /force for Windows. Any user going cross platform has a similar utility to use. And I am always changing something and have to ask users to logout and back in again for changes to take effect and is a huge pain for end users. Being able to run a command to mcxrefresh is nice to update the MCX settings while the user is logged in.
