Get rid of duplicates on the ‘Open With…’ menu

Getting rid of duplicates on the ‘Open With…’ menu is pretty simple, all you need to do is open the Terminal and enter the following commands:

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

killall Finder

That’s all you need to do…although the duplicates might reappear after a while, so you’ll have to repeat the process.
