How do I turn on OS X Mavericks "single application" mode?

The single application Mode is a hidden feature that OS X has always supported, the effect is that when you click an application on the Dock with your mouse or touchpad, all other application windows are minimized, which can greatly prevent you from being distracted by other application windows while working on certain applications. And your screen space will not be occupied by other cluttered windows.

To turn on "single application" mode, you must run a "terminal" command to take effect:

Defaults write Com.apple.dock single-app-bool true && killall Dock

It should be noted that single application mode is only valid for you to switch applications on the Dock bar, otherwise it is invalid (such as Command+tab), we will try to know.

To return to normal mode, run the command:

Defaults Delete com.apple.dock Single-app && killall Dock
