What does force eject mean on a Mac?

For Mac users, the term “force eject” can be confusing. In simple terms, force eject on a Mac does not mean pulling out a drive in an unsafe way. Instead, it usually refers to trying stronger software methods to remove a drive when the normal Eject option does not work.

On macOS, an external drive may fail to eject because it is still being used. This use can come from open files, running apps, or background system processes. When this happens, macOS blocks ejection to protect your data. You may see a message saying the disk is in use and cannot be ejected.

So, what does force eject mean on a Mac in practice? It means asking the system to release the drive by stopping or closing whatever is using it. This can include quitting apps, logging out of your account, restarting Finder, or using built-in system tools to unmount the disk. Some users also rely on third-party disk tools to help manage these locks more smoothly.

It is important to know that macOS does not truly allow unsafe force ejection while data is being written. This design helps prevent file corruption, data loss, and drive damage. The purpose of “force eject” is still safe unmounting, not physical removal. Once the drive is fully unmounted and disappears from the desktop, it is safe to unplug it.

Why Mac sometimes cannot eject an external hard drive

Before looking for solutions, it helps to understand why a Mac sometimes cannot eject an external hard drive. In most situations, this is not a system error. macOS is simply trying to protect your files and prevent data loss. When the system believes a drive is still active, it will stop the ejection process. There are some common reasons a Mac cannot eject an external hard drive

Cause Explanation
Background system activity macOS may be running hidden tasks on the drive, such as indexing files, creating previews, checking backup availability, scanning media, or monitoring storage for security purposes. These actions can keep the drive busy even when no files are open.
Files or apps still in use If an app is using a file stored on the external drive, macOS will block ejection. This can happen even when the app is minimized or running quietly in the background.
Finder access An open Finder window showing the external drive can prevent ejection. Finder may still be reading file details or metadata, which counts as active use.
NTFS file system limits Many external drives use the NTFS format. On macOS, NTFS is usually read-only and has limited compatibility, which can cause unstable mounting and unmounting behavior. This often leads to “disk is in use” messages.

Because of these reasons, macOS may refuse to eject a drive until all activity fully stops. To safely remove the drive and protect your data, make sure all programs and processes accessing it are closed first.

How to force eject on Mac with an external hard drive? 

Fix 1. Safely force eject an external hard drive on Mac

Ejecting an external hard drive on a Mac is usually simple, but sometimes macOS shows errors like “The disk is in use” or “One or more programs may be using this disk.” Directly unplugging the drive can risk data loss.

This problem often occurs with NTFS drives, as macOS can read but not write to them by default. PartitionAssistant NTFS for Mac solves this by providing full read/write access, allowing safe file management and secure ejection.

Force ejecting a drive means disconnecting it safely when macOS reports it as in use. While Terminal commands or force-quitting apps are possible, they risk data loss. PartitionAssistant NTFS for Mac offers a safer, professional solution, supporting NTFS, FAT32, and exFAT drives, and working on both Intel and Apple Silicon Macs. With this tool, ejecting stubborn external drives becomes simple, safe, and reliable.

Fix 2. Safely eject external hard drive with the Finder Sidebar

Using the Finder sidebar to safely eject an external hard drive on a Mac ensures the system properly closes all files and stops any processes connected to the drive before removal. This prevents data loss by avoiding corrupting files that are still being read or written and maintains the integrity of the drive’s file system, especially for NTFS or other non-native macOS formats. Ejecting through Finder is simple and safe, and macOS will alert you if the drive is still in use, giving you a chance to close apps or wait for operations to finish.

Step 1. Open a Finder window.

Step 2. Look at the sidebar on the left under the "Locations" section.

Step 3. Find your external drive in the list.

Step 4. Click the small Eject icon (an arrow pointing up with a line under it) next to the drive name.

Fix 3. Drag external hard drive to Trash

In addition to the other methods, you can use the Trash on your Mac to safely eject an external hard drive.

Step 1. Locate your external storage device's icon on the desktop and drag it to the Trash bin. The Trash bin will now change to an Eject icon. 

Alternatively, you can hold the "Ctrl" key and press the left-click button on your mouse on the external disk's icon to popup the menu and then click on the Eject button. 

Step 2. If the icon is no longer visible, you have safely ejected your external disk. And now, you can disconnect the external device from your Mac.
