OS X Open With Out-of-date

On my Mac system I’ve noticed that, for some reason, multiple versions of a program, or even programs I no longer have installed, will show on the “Open with” menu in finder. Something like what you see in the screenshot.

Turns out this list is a sort of internal database that needs to be cleaned once in a while, but I’m not sure why the system fails to do this on it’s own. Regardless, this can be corrected by triggering a refresh of the database system and then re-launching the Finder.

Open Terminal and paste the following exactly, it should be all on one line:

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

After that command finishes, hold down the Control + Option keys on your keyboard, then click on the Finder icon and select “Relaunch”
