How does the Mac system remove a duplicate item from the right mouse button menu?

I am a loyal Mac fan, I love my Mac, and her time is always good. But sometimes she does something weird, like when I right-click on a file and I'm looking for the right app to open, I find out that she's showing some repetitive options. Although it does not affect the use, but for me, this is to drive me crazy rhythm.

It turned out that the solution to the problem was fairly easy. We just need to use the "terminal" application.

To delete a right-click menu duplicate item by using terminal

First step: Open the terminal application.

Step Two: Enter the following command.

/system/library/frameworks/coreservices.framework/versions/a/frameworks/launchservices.framework/versions/a/ Support/lsregister-kill-r-domain Local-domain User

The third step: press the "return" key.

Now when you right-click a file again and hover over the "open with" option, you'll notice that the duplicate right menu items have been cleaned up and refreshed.

The next time the right-click menu repeats itself, be sure to try the command.

One might think that this tutorial is over. Oh no......

Given that someone will forget this terminal command, we can use the Automator application to create an application or a right-click menu service. Because of my previous article how to exit all open applications tutorial has demonstrated how to create a Automator application. This time we're going to create a right-click menu service so that when you find duplicates in the right-click menu, you can move directly to the bottom of the right button menu. Service "Item to find this feature.

Don't say much nonsense, we started to do it.

The third step: Select the "service" input source, where we choose the "Files and folders" option.

End Run

Note: In fact you only need to change the middle bracket in the "*your script goes here*" that part can be.

Sixth step: Press "command + s" shortcut key, pop-up service naming panel, here we will name it "clear duplicates."

Well, the next time you find the right key menu duplicate options, just go to the bottom of the "Services" option, select "Clear Duplicates" can be.

Of course, you can also assign shortcut keys to this service.
