Remove Multiple ‘Open With’ Menu Items – Command Line

Command Line Network Configuration
So, I had this annoying situation the other day, when I CTRL Clicked on a file and chose Open With, I was presented with this menu


Multiple versions of Excel and Word to choose from, probably caused by software updates, anyway, I didn’t like this, it made the menu looked cluttered, so to remove it, you need to open Terminal and enter the following line of code

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

It takes a few seconds to work, but afterwards you should end up with less cluttered menus


You may need to relaunch Finder, which is done by pressing CTRL, ALT and clicking on the Finder icon in the Dock, then click on relaunch

Managed Preferences – Cache Flush


The other day I was trying to access some restricted preferences on a 10.6 client, bound to a 10.6 Server that no longer existed, and because of this, I had no way of removing the restrictions

Or so I thought, thankfully Apple had provided a Knowledge Base article detailing how to manually flush the cache, enabling access to the previously restricted preferences.

To do this, I opened up Terminal and input the following command all on one line

dscl . -list Computers | grep -v "^localhost$" | while read computer_name ; 
do sudo dscl . -delete Computers/"$computer_name" ; done

This worked, I was able to amend the settings needed, I have provided the link to the Apple page below, in case you need information on how to do this on earlier OS’s
