How to Make Dock Icons Smaller on a MacBook Air (and Remove Apps)

Use System Settings to shrink the Dock, remove an app shortcut while keeping the app, or uninstall the app itself when that is your goal.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To make Dock icons smaller, open Apple menu > System Settings > Desktop & Dock and drag the Size slider to the left. To remove an app from the Dock without uninstalling it, drag its icon out of the Dock until Remove appears, then release; the app stays on your Mac.

Make the Dock icons smaller

  1. Open the Apple menu and select System Settings.

  2. Select Desktop & Dock in the sidebar. You may need to scroll to find it.

  3. Under Dock, drag the Size slider left until the Dock is the size you want. Apple documents this control in its Desktop & Dock settings guide.

Adjust magnification separately

If icons enlarge when the pointer moves over them, look for Magnification in the same settings panel. Turn it off or reduce its slider. Size changes the Dock’s overall size; Magnification controls the pointer-hover effect.

Resize without opening Settings

Move the pointer over the Dock’s separator line until it becomes a double arrow, then drag to resize. Apple describes this alternative in its desktop and Dock guide.

Make the Dock take up less screen space

In System Settings > Desktop & Dock, you can also move the Dock to the left or right edge of the screen, or enable automatic hiding so it appears only when needed. These options change its position or visibility rather than the icon size.

Remove an app from the Dock but keep it installed

  1. Drag the app’s icon out of the Dock.

  2. Release it when Remove appears.

This removes only the Dock shortcut; it does not uninstall the app. To put the app back, open it, Control-click its Dock icon, then choose Options > Keep in Dock. Apple explains these Dock actions in its Dock guide.

Clear a question-mark icon

If an app has already been deleted but its Dock icon remains with a question mark, drag that icon out of the Dock and release when Remove appears. This clears the stale shortcut; Apple’s question-mark Dock icon guide covers this case.

Uninstall the app itself

Uninstalling is different from removing an icon. For a third-party app, quit it, locate it in Finder, and check first for an uninstaller or removal feature supplied with the app. Apple recommends using that option when available because related login items, extensions, or other data may be stored outside the app itself.

If there is no uninstaller, move the app from Finder to the Trash. Empty the Trash to permanently delete it. Apple notes that some apps installed with macOS, and items in the System folder, cannot be deleted this way. Its app deletion and uninstallation instructions explain the process.

Choose the right kind of removal

Action What changes Storage effect Can you undo it?
Remove the Dock shortcut The icon disappears from the Dock; the app remains installed. No app storage is freed. Yes. Open the app, Control-click its Dock icon, then choose Options > Keep in Dock.
Uninstall the app The app is removed from the Mac, subject to macOS restrictions and any app-specific uninstaller. App storage is freed after permanent deletion; related files or user documents may remain. Not by restoring the Dock shortcut alone. Reinstall the app if you want it back.

Menu labels can vary by macOS version or language. These are Mac-wide instructions; the steps do not depend on a particular MacBook Air model.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
