The first thing you should do to perfect your dock is adjust the size—and if you want it to be smaller or larger, there’s a way to do it without messing around in settings. Move your mouse cursor towards any separator in the dock (those vertical dividing lines). The cursor will change to an arrow that points up and down. When it does, drag it towards the top of the screen to make the dock larger or drag it downwards to make it smaller.

Alternatively, you can adjust the dock’s size by going to System Preferences > Dock & Menu Bar and moving the Size slider. The dock’s size increases if you move the slider to the right and it decreases if you move it towards the left. But why would you bother with that?

The dock can be moved to either side of the screen to save precious screen real estate. To change this quickly, right-click any vacant area in the dock (not on any app icon), and select Position on Screen. You can then pick Left or Right.

This option is also available next to System Preferences > Dock & Menu Bar > Position on screen:.

Up to three apps you’ve opened recently show up on the right side of the dock. If this annoys you, disable the setting by going to System Preferences > Dock & Menu Bar and disabling Show recent applications in Dock.

Whenever you minimize apps on your Mac, each window appears as a separate icon on the dock. This can cause the dock to fill up, reducing its size on your screen automatically. If you’d rather it not, macOS allows you to minimize directly into the app’s icon instead. You can get this done by going to System Preferences > Dock & Menu Bar and selecting Minimize windows into application icon.

If an app is open on your Mac, a small dot appears near its icon on the dock. You can remove these open app indicators if you wish to do so. Go to System Preferences > Dock & Menu Bar and disable Show indicators for open applications.

When you move your cursor near any app icon on your Mac’s dock, it’ll automatically enlarge. You can change the level of this magnification effect, or disable it altogether by going to System Preferences > Dock & Menu Bar.

To enable or disable enlarging icons, check or uncheck Magnification. There’s a slider below this option that lets you adjust the size of enlarged icons. Fun tip: If you have this feature disabled, you can temporarily activate it on command by holding Shift + Control.

If you want a radically different dock that shows just the apps that are currently running on your Mac, a simple Terminal command will get it done—but proceed with caution, because a bug sometimes prevents you from later restoring the dock to its original state, forcing you to reset the dock to its default settings.

If you’re ready to take the plunge, open Terminal and paste in this command: defaults write com.apple.dock static-only -bool true; killall Dock. This will remove all pinned apps from the Mac’s dock and switch to a display of running apps only. To restore the dock to its previous state, this command in Terminal should work: defaults write com.apple.dock static-only -bool false; killall Dock.

If the restore command doesn’t work, reset the dock to factory settings with the following command: defaults delete com.apple.dock; killall Dock. This will change the dock to how would look after a clean install of macOS.

You can add browsable folders to the Mac’s dock, provided long as the folder is in the Favorites bar in Finder. Open Finder and locate the folder you want to add and drag it to the Favorites bar in the left pane. Right-click any folder in the Favorites bar and select Add to Dock.
