macOS Drag and Drop Not Working — What It Means & How to Fix It

What Does This Error Mean?

When drag and drop stops working on a Mac, you cannot move files in Finder, drag text between apps, or use trackpad gestures for moving items. This is almost always a macOS software glitch that a restart or a Dock/Finder restart fixes in seconds. Killing the Dock process via Terminal is the fastest fix if a full restart is not convenient.

Affected Models

macOS Ventura (13)
macOS Sonoma (14)
macOS Sequoia (15)
MacBook Pro
MacBook Air
Mac mini

Common Causes

macOS Dock has encountered a software glitch affecting drag and drop
Accessibility settings (such as Mouse Keys) are interfering with drag and drop
Three-finger drag is disabled on the trackpad and the drag gesture is not working
A third-party app or accessibility tool has taken over mouse/trackpad input
macOS software bug introduced by a recent update

How to Fix It

Open Terminal (Applications > Utilities > Terminal) and type: killall Dock then press Return.

This restarts the Dock process, which manages drag-and-drop in macOS — it takes about 2 seconds and often fixes the issue immediately.
If that does not work, restart the Finder: hold Option, click Finder in the Dock, and select Relaunch.

A Finder restart takes 5 seconds and resolves drag-and-drop issues caused by a stuck Finder process.
Check that Mouse Keys is not enabled: System Settings > Accessibility > Pointer Control > Alternate Control Methods.

Mouse Keys lets you control the cursor with the keyboard — when enabled, it can interfere with drag and drop.
Check Trackpad drag settings: System Settings > Accessibility > Pointer Control > Trackpad Options > Dragging Style.

Enable 'Three Finger Drag' or 'Drag Lock' depending on your preferred drag style.
Restart the Mac if the above steps do not resolve the issue.

A full restart clears all session state and resolves the vast majority of drag-and-drop failures.
Check for a macOS update via System Settings > General > Software Update.

Apple has fixed drag-and-drop bugs in minor macOS point releases — installing updates prevents recurrence.

When to Call a Professional

Contact Apple Support if drag and drop consistently fails after all steps below. A macOS reinstall (preserving data) can resolve persistent drag-and-drop failures caused by system file corruption. Apple Support can perform remote diagnostics to check for underlying system issues.

Frequently Asked Questions

Why does drag and drop stop working randomly on Mac?

macOS's drag-and-drop system is managed by the Dock process, which can occasionally get stuck. This happens more often after the Mac has been running for many days without a restart. Running 'killall Dock' in Terminal restarts the Dock process and fixes it instantly without restarting the Mac.

How do I enable three-finger drag on my Mac trackpad?

Go to System Settings > Accessibility > Pointer Control > Trackpad Options. Enable the 'Use trackpad for dragging' option and set the style to 'Three Finger Drag'. With three-finger drag enabled, you use three fingers to click-and-hold to drag items.

Drag and drop works in Finder but not between apps — why?

Inter-app drag and drop is handled differently from in-Finder dragging and may involve app-specific permissions. Some apps restrict drag-and-drop from external sources for security reasons. If dragging works in one app but not another, the receiving app may not support that drag type — try copy-paste instead.
