Execution of commands by dragging and dropping objects onto others on Apple Mac computers is used much more often than on Windows machines. Conveniently! But sometimes it happens that drag’n’drop not working on Mac. How to be? There are some simple solutions.
- 'Yoink is a fantastic way to enhance drag'n'drop. Highly recommended.' - Federico Viticci, MacStories.net 'Yoink is an awesome drag and drop utility for the Mac and is instrumental to me when working with full screen apps.' - Jeff Benjamin, iDownloadBlog.
- Again, a single tap will end the drag without the delay. Drag Lock works with both the 'one-finger tap & drag' and the 'three-finger drag'. When enabled, the drag does not end after lifting your finger(s) from the trackpad. Rather you have to tap/click the trackpad to end the drag.
If you cannot drag and drop when working with files and folders, often the most obvious and simple solution is to restart the macOS file manager. This can be done like this:
- Hold the Option key;
- Right-click on the Finder icon in the Dock;
- In the context menu, select Relaunch.
For closer integration between Mac OS X and your Windows guest OS, Parallels Desktop provides the possibility to copy and paste formatted text, pictures and drag and drop files between Mac OS X and the virtual machine operating system.
If restarting Finder did not help, the next way to solve the problem with a failed drag’n’drop is to restart the system entirely. This can be done either through the Apple menu -> Restart. After the computer restarts, check if the drag and drop works in the applications you need. If it works, hooray hooray! If not, go deep into the library files.

Delete Finder Settings Files and Reboot
If the two previous methods were unsuccessful and drag and drop still not working on Mac, it may be that the settings of the mouse or trackpad drivers are damaged. In this case, it is enough to delete them and restart the Mac, so that new files appear on the site of the deleted files without erroneous data. What should be done:
- Going to Finder, press the keys Shift + Command + G, in the appeared window enter the path ~/Library/Preferences/ and press the enter key;
- Go to the Preferences folder, find and select the following files:
- Delete these files to the Trash and Reload the Mac again. After logging in again, test the performance of the drag’n’drop operations.
Users often complained that they can’t Drag and Drop Mac’s files. In my personal view, the problem is exaggerated because its solution is often limited to restarting Finder or restarting the macOS. In my practice, there was only once the need to use the solution while digging into the System files for managing manipulators and deleting them.
In computergraphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by 'grabbing' it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects.
As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what is the command performed by the drag and drop, which can decrease usability.
The basic sequence involved in drag and drop is:
- Move the pointer to the object
- Press, and hold down, the button on the mouse or other pointing device, to 'grab' the object
- 'Drag' the object to the desired location by moving the pointer to this one
- 'Drop' the object by releasing the button
Dragging requires more physical effort than moving the same pointing device without holding down any buttons. Because of this, a user cannot move as quickly and precisely while dragging (see Fitts' law). However, drag-and-drop operations have the advantage of thoughtfully chunking together two operands (the object to drag, and the drop location) into a single action.Extended dragging and dropping (as in graphic design) can stress the mousing hand.
A design problem appears when the same button selects and drags items. Imprecise movement can cause an attempt to select an object to register as a dragging motion.
Another problem is that the target of the dropping can be hidden under other objects. The user would have to stop the dragging, make both the source and the target visible and start again. In classic Mac OS the top-of-screen menu bar served as a universal 'drag cancel' target. This issue has been dealt with in Mac OS X with the introduction of Exposé.
In Mac OS
Drag and drop, called click and drag at the time, was used in the original Macintosh to manipulate files (for example, copying them between disks or folders.). System 7 added the ability to open a document in an application by dropping the document icon onto the application's icon.
In System 7.5, drag and drop was extended to common clipboard operations like copying or moving textual content within a document. Content could also be dragged into the filesystem to create a 'clipping file' which could then be stored and reused.
For most of its history Mac OS has used a single button mouse with the button covering a large portion of the top surface of the mouse. This may mitigate the ergonomic concerns of keeping the button pressed while dragging.
The Workplace Shell of OS/2 uses dragging and dropping extensively with the secondary mouse button, leaving the primary one for selection and clicking.Its use like that of other advanced Common User Access features distinguished native OS/2 applications from platform-independent ports.
The HTML5 working draft specification includes support for drag and drop. HTML5 supports different kinds of dragging and dropping features including:
- Drag and Drop texts and HTML codes
- Drag and Drop HTML elements
- Drag and Drop files
Based on needed action, one of the above types can be used. Note that when an HTML element is dragged for moving its current position, its ID is sent to the destination parent element; so it sends a text and can be considered as the first group.
Google's web-based e-mail application Gmail supports drag-and-drop of images and attachments in the latest Google Chrome browser and Apple's Safari (5.x). And Google Image search supports drag & drop.
On a touch screen
Touch screen interfaces also include drag and drop, or more precisely, long press, and then drag, e.g. on the iPhone or Android home screens.
iOS 11 implements a drag-and-drop feature which allows the user to touch items (and tap with other fingers to drag more) within an app or between apps on iPads. On iPhones, the functionality is only available within the same app that the user started the drag.
In end-user programming
Drag and drop is considered an important program construction approach in many end-user development systems. In contrast to more traditional, text-based programming languages, many end-user programming languages are based on visual components such as tiles or icons that are manipulated by end users through drag-and-drop interfaces. AgentSheets, a programming environment for kids, introduced the modern notion of drag and drop blocks programming providing 4 core affordances: 1) Blocks that are end-user composable, 2) blocks are end-user editable, 3) blocks can be nested to represent tree structures, 4) blocks are arranged geometrically to define syntax. Drag and drop is also featured in many shader editing programs for graphics tools, such as Blender. Drag and drop also features in some video game engines, including Unreal Engine, GameMaker Studio, Construct 2 and, with expansion, Unity (game engine).
A common example is dragging an icon on a virtual desktop to a special trashcanicon to delete a file.
Further examples include:
- Dragging a data file onto a programicon or window for viewing or processing. For instance, dropping an icon that represents a text file into a Microsoft Word window signifies 'Open this document as a new document in Word'
- Moving or copying files to a new location/directory/folder,
- Adding objects to a list of objects to be processed,
- Rearranging widgets in a graphical user interface to customize their layout,
- Dragging an attribute onto an object to which the command is to be applied,
- e.g. dragging a color onto a graphical object to change its color,
- Dragging a tool to a canvas location to apply the tool at that location,
- Creating a hyperlink from one location or word to another location or document.
- Most word processors allow dragging selected text from one point to another.
- Dragging a series of code blocks such as in Blender for designing shaders and materials.
