How To Remove Duplicate Apps In Mac OS X Right Click Menu

The ‘Open With’ feature in right-click menu allows us to open a specific file with applications other than the one associated with the document type. Normally it will display all compatible apps to open a specific file but sometimes, it will display more than one selection for the same app in the ‘Open With’ menu.

If you’re annoyed by this harmless bug, we have a solution to remove duplicate apps in the ‘Open With’ menu.
