Drag and drop on a Mac, the complete guide

How does drag and drop work on a Mac, and when does it copy instead of move?

Apple's Mac User Guide describes drag and drop in three steps: select the item, press and hold the trackpad or mouse while you move it, and release it where it belongs. That works for files in Finder, but also for a block of text, an image in a document, a photo in Photos or a link in Safari. Whatever accepts the drop decides what happens to it.

For files in Finder there is one rule underneath that causes most of the surprises. A drag inside the same disk moves the file: it leaves the old folder and appears in the new one. A drag onto a different disk (an external drive, a USB stick, a network share) copies it, so the original stays where it was. Apple's Mac keyboard shortcuts page states the rule in reverse when it lists the exception: "Command key while dragging to another volume: Move the dragged item to the other volume, instead of copying it."

Before you let go, look at the pointer. Finder shows a small plus badge next to it when the drop will make a copy, and a curved arrow when it will make an alias. No badge means a move. If you see a circle with a line through it, the place under the pointer doesn't accept the drop; Apple's Universal Control page uses the same symbol for the same meaning.

Coming from Windows: what is different

Less than it seems. Windows File Explorer uses the same volume rule, and its modifier keys map almost one to one. Raymond Chen, who worked on the Windows shell, wrote the rules down in The Old New Thing: no modifier moves on the same drive and copies across drives, Ctrl copies, Shift moves, Ctrl+Shift makes a shortcut.

The two habits that trip switchers up are the keys and the windows. The Mac's Option key does what Ctrl did, and Command does what Shift did. And on a Mac, an app's window stays where it is when you switch away, so the target you want is often hidden behind something else. Most of the wrong drops come from letting go over the wrong window, not from the copy and move rules. The next sections deal with both.

Modifier keys that change a drag

Here is what each one does, in Apple's words from the keyboard shortcuts page:

• Option while dragging: "Copy the dragged item. The pointer changes while you drag the item." Use it to duplicate a file into another folder on the same disk, or to leave a copy behind when you drag something into a project folder.
• Command while dragging to another volume: "Move the dragged item to the other volume, instead of copying it." Use it when you are clearing files off the Mac onto an external drive and don't want to delete the originals by hand afterwards.
• Option-Command while dragging: "Make an alias of the dragged item." The alias is a small pointer to the original. Open it, and the original opens.

You don't need to hold the key from the start. Press it while the file is already in the air, watch the badge change, and let go. Release the key before you drop and the drag goes back to its default.

Dragging into the Dock follows its own rules. Apple's Dock guide says items you add there become aliases, so a folder dragged into the Dock stays where it is on disk. Dragging an item out of the Dock until Remove appears removes only the alias.

How the rules work for the less obvious cases (iCloud Drive, a network share, a file dragged out of an app instead of Finder) is covered in copy or move: what dragging a file does on a Mac.

Drag a file to an app that's hidden behind other windows

The difficulty with a hidden target is that you have to find it while the drag is in progress. Every one of these methods keeps the drag alive while you go looking.

Command-Tab while you drag

Start the drag, keep the button or trackpad held, and press Command-Tab with the other hand. Apple describes Command-Tab as switching to "the next most recently used app among your open apps" (keyboard shortcuts). Tab to the app you want and let go of the keys: the app comes forward with the file still under your pointer. Drop it into the window. Macworld described this in a 2006 tip on drag and drop and app switching, and MacMost still shows the same move in 2022.

MacMost's 15 drag and drop techniques adds a shortcut to the shortcut: drop the file on an app's icon in the switcher itself, and the file opens in that app. That is handy when you want the file opened, not placed in a particular window.

Drop on the Dock icon

If the app is in the Dock, you don't need to bring it forward at all. Apple's Dock guide says to "Drag the file over an app's icon"; the app opens the file. While you drag, the icons of apps that can open that kind of file highlight, as MacMost points out, so you can see where a drop will work before you make it.

Mission Control while you drag

Hold the file and press Control-Up Arrow, which opens Mission Control (keyboard shortcuts), or swipe up with four fingers on the trackpad (Multi-Touch gestures). Every open window spreads out; drag the file onto the one you want and wait a moment for it to come forward, then drop. MacMost's short version: "You can always use Mission Control as well."

Which one to use

Spring-loaded folders, the sidebar and the path bar

Apple's Pointer Control settings page describes spring-loading as: "When dragging and dropping, drag an item to a folder and hold to open the folder." Next to it is Spring-loading speed, which sets how long you have to hover before the folder opens. If folders keep popping open when you only meant to pass over them, slow it down; if you find yourself waiting, speed it up. MacMost notes in 10 ways to move files on a Mac that pressing the Space bar while you hover opens the folder at once.

Spring-loading works on folders in a Finder window, in the sidebar and on the Desktop. Combined with the sidebar, it gives you a way to reach most of the Mac without opening a second window: drag the file to Documents in the sidebar, hover, and keep hovering through the subfolders until you reach the right one.

Three other Finder targets accept drops and are easy to forget:

• Sidebar favorites. Dropping a file on a folder in the sidebar moves it there, even when that folder isn't open.
• The path bar. With View > Show Path Bar on, every folder in the path at the bottom of the window is a drop target, so you can move a file up one or two levels in one drag.
• Folders in the Dock. A folder you've added to the right side of the Dock takes drops like any other folder.

There is more on setting it up, and on the cases where it gets in the way, in spring-loaded folders on a Mac.

Make dragging on a trackpad less fiddly

The default trackpad drag is press and slide, and it fails in a predictable way: your finger reaches the edge of the trackpad before the pointer reaches the target, you lift it to reposition, and the file drops wherever it happens to be. MacMost's guide to making drag and drop easier suggests one fix that needs no setting at all: click and hold with your thumb and slide with your index finger, so you can lift and reposition the sliding finger without letting go.

The settings fix is in Trackpad Options. Apple's three finger drag page walks through it: System Settings > Accessibility > Pointer Control, click Trackpad Options, turn on "Use trackpad for dragging", and choose a dragging style. The Pointer Control reference lists three:

Apple notes that three finger drag is "an option for trackpads that support Force Touch". Its Multi-Touch gestures page lists Mission Control and swiping between full-screen apps as four-finger gestures, so they don't clash with a three-finger drag.

Which one to pick depends on how you drag. If most drags are short and within one window, three finger drag is the most comfortable and needs no click. If you often carry files across a large display or from one display to another, drag lock is the safer choice, because lifting a finger never drops the file. The full comparison, including what each does to text selection, is in three-finger drag and drag lock on a Mac trackpad. If dragging stops working altogether, start with drag and drop not working on Mac.

Drag between apps, Spaces and devices

Drag and drop works far outside Finder. Almost anything you can see can be picked up and put somewhere else, and many apps do something useful with it. A few that MacMost demonstrates in its 15 drag and drop techniques:

• Into a document or message. Drop an image into Pages, Keynote or Mail and it is inserted where you let go.
• Out of Photos. Drag a photo from Photos to a Finder window or the Desktop; MacMost calls it "an export just with a drag and drop".
• Into a website. Drop files onto an upload box in Safari or Chrome instead of clicking Choose File and browsing. The details, and what to do when a site ignores the drop, are in drag files into a browser upload on a Mac.
• Text. Select text and drag it into another app to insert it. Drop it on the Desktop and you get a text clipping file.

Into Open and Save dialogs and Terminal

Two tricks save a lot of browsing. Drag a folder (or a file) from Finder into an Open or Save dialog, and the dialog jumps straight to that location. Drag a file into a Terminal window, and Terminal types its full path, with spaces already escaped. There are more ways to get a file's path in how to copy a file path on a Mac.

Across Spaces and full-screen apps

This is where plain drag and drop is weakest. Apple's guide to Spaces explains how to switch Spaces (Control and an arrow key, or a swipe) and how to move a whole window to another one, but not how to carry a single file across. The built-in way is to hold the file, open Mission Control, hover over the target Space in the Spaces bar until it comes forward, and drop. It works, but the whole trip happens with the button held. The step-by-step version, with the alternatives, is in how to drag files between Spaces and full-screen apps. Two displays have a similar problem, covered in moving files between two displays on a Mac.

To an iPad or another Mac

With Universal Control, one keyboard and pointer work across a Mac and an iPad, or two Macs, and a drag goes with the pointer. Apple's Universal Control page says it supports "using your mouse or trackpad to drag and drop between devices", for example a photo from the Mac into Messages on the iPad, or files into the iPad's Files app. It needs macOS Monterey 12.4 or later and iPadOS 15.4 or later, with the devices within 10 meters (30 feet) of each other. Push the pointer past the edge of the screen with the file held, and it continues on the other device.

Move files without dragging at all

Apple's keyboard shortcuts page lists Option-Command-V as "Move the files in the Clipboard from their original location to the current location." In practice it means you never need two Finder windows side by side: copy, navigate the same window to the destination, and move.

MacMost points out the advantage over Windows-style cut in 10 ways to move files on a Mac: "it doesn't leave the file in limbo anywhere." Until you paste, the file hasn't gone anywhere. If you open the Edit menu after copying and hold Option, the Paste Item command turns into Move Item Here, so you can do the same with the mouse. More on the differences from Windows, and the cases where it doesn't work, in cut and paste files on a Mac.

Keyboard moves are often faster than dragging for one file between two folders. They don't help with getting a file into an app, though, and that is still drag and drop's job.

When one drag is not enough: use a shelf

Every trick above is a way to do more while holding a file. They work for one file and one target. They get awkward when the files come from three different folders, when the target is in another Space or a full-screen app, or when you need to look something up before you drop. The usual workaround is the Desktop: drop the files there, go to the target, drag them back out, and tidy up later. A shelf does the same parking without leaving anything behind. Using the Desktop as a temporary folder goes into why that habit costs more than it seems.

Dropover, Yoink and cursorrobin are all shelf apps; they differ mostly in where the shelf appears and what it can do with the files. cursorrobin's version:

Unlike a Finder drag, a shelf never moves your original: cursorrobin copies each file onto the shelf, and the copy (or the converted copy) is what you drag out. That makes the copy and move rules from the start of this guide irrelevant while the files are on the shelf.

A shelf is not the answer for every drag. If the source and the target are both on screen, a plain drag is quicker. If you only ever move files between folders, spring-loading and Option-Command-V are free and already on your Mac. A shelf earns its place when you do the awkward kind of drag every day. A file shelf app for Mac that follows your cursor explains the jobs where it helps most, and the best file shelf apps for Mac compares the options.
