In Mac OS X, you can right click and choose "Open With" in the menu to select any one way when you want to open a file. System may automatically offer you the proper software to open the file. However, occasionally, there're many duplicated items wrongly appearing in the menu of "Open With". Is there any ways to remove these annoying items? Yes, certainly! Just follow the simple steps below. All you need is a terminal command.
