本文介绍如何通过重建LaunchServices数据库来清除Mac上'打开方式'菜单中的重复项和已删除的应用程序条目。您可以通过第三方工具或者使用内置的Terminal应用程序自行完成这一过程。

Resetting the 'Open With' Menu

Resetting the 'Open With' menu will remove duplicates and ghost applications (ones you have deleted) from the list. You reset the 'Open With' menu by rebuilding the Launch Services database your Mac maintains. There are multiple ways to rebuild the Launch Services database, including third-party system utilities like Cocktail andOnxy.

If you don't own a system utility that can rebuild the Launch Services database, don't worry; you can perform the rebuild yourself using Terminal.

Using Terminal to Rebuild the Launch Services Database

Launch Terminal, located at /Applications/ Utilities/.

For OS X 10.5.x and later, enter the following at the Terminal prompt:

在终端中键入下列命令（将下面的路径整个拷贝或进入Support目录下）：

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

For OS X 10.3.x - 10.4.x, enter the following at the Terminal prompt:

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

The above is one command and is entered on a single line. You can simply copy/paste the above command into Terminal, then press Return/Enter to execute the command.

The rebuild process can take a minute or two. Once the Terminal prompt returns, you can quit Terminal.

Now when you use the 'Open With' menu, you should see an application list that's limited to the applications currently installed on your Mac, with no duplicates or ghosts.
