Instructions to enable hidden features for dock on Mac OS

Normally, when clicking on the application icon on the Mac dock bar, the open windows of that application will be displayed. And to be able to find which window you are working on, you need to manipulate it, especially if we open multiple windows it will take some time.

This is different from Windows, when we hover over the open application icon on the computer in the taskbar, if you open multiple windows you just need to select a minimized window to do it. Immediately that window will appear on the computer interface. So can bring useful features of taskbar on Windows to the dock on Mac? The answer is yes. And the operation is also simple, just need to do with the command line only on Terminal.

Step 1:

First, click Applications and select Utilities, then select Terminal to open the window. Or you can type the keyword Terminal on the Spotlight search engine.

Step 2:

In the new Terminal command window that appears, we will enter the following line of code:

defaults write com.apple.dock scroll-to-open -bool true; killall Dock

Finally press Enter to get the command line executed. The dock bar below the screen will disappear in seconds.

Step 3:

When the dock appears again, use the scroll button to scroll down to the open application icons on the device. Soon, the windows of the application in use will appear on the screen. And you can just click the window you want to use.

Step 4:

To disable the hidden feature on the dock bar and return to the same status, change true in the Terminal command line to false:

defaults write com.apple.dock scroll-to-open -bool false ; killall Dock

Also press Enter so the command line is executed.

So with just a simple command line on Terminal you can customize the dock on your Mac quickly. From there, we can easily open the window we need on the application faster, without having to add some search operations like before.
