To solve the problem that the USB or external hard disk cannot be safely unplugged on a Mac, first check the desktop icon popup, Finder popup, docking operation, or uninstall using Disk Tool. 1. Desktop icon pops up: Right-click the disk icon and select "Express" or drag to the "Pop" area next to the Docking Trash; 2. Finder pops up: Find the device in the Finder sidebar and click the "Eject" button; 3. Docking operation: Right-click the device name and select "Express" or drag to the "Eject" area; 4. Force pops up: Close the occupant program or uninstall it through "Disk Utility". Be sure to develop the habit of popping out first and then pulling out to avoid data corruption.

You may have encountered this situation when using a Mac: the inserted USB drive or external hard drive cannot be directly pulled out, and forcibly unplugged may also prompt "in use". At this time, you need to "eject" the disk correctly. Don't worry, the operation is actually very simple, as long as the method is correct, it can be pulled out safely.

Use the desktop icon to pop up

If you can see the icons that plug into the device on your desktop, this is the most intuitive way.

• Click the disk icon on the desktop and select it
• Then right-click and select "Put Up" (or "Pop")
• You can also directly drag the disk icon to the wastebasket on the dock, and that position will become a "pop-up" icon.

It will be safe to unplug the device after the icon disappears. This method is suitable for most ordinary users, especially those who are not very familiar with menu bar operations.

Eject disk via Finder

If you have already opened Finder, you can also operate here:

1. Open Finder
2. Find your disk device in the left sidebar (usually under "Location" or "External")
3. Click the "Pop" button next to the disk name on the right (small triangle icon)

The advantage of this method is that it is not easy to operate incorrectly, and it is especially suitable for connecting multiple devices at the same time.

Quick operation with the program dock

Mac's program docking can actually help you quickly eject disks:

• After plugging in the device, you will see its name appear on the dock
• Right-click the device name → select "Premises"
• Or drag it directly to the "pop-up" area next to the wastebasket

This method is especially suitable for users with mouse operating habits, and the visual feedback is also clear.

Method of forcing pop-up (not recommended for common use)

Sometimes the disk is stuck and the system prompts "The disk is in use". You can try the following method:

• Check if there are any programs that are still accessing files on this disk (such as preview, Photoshop, terminal, etc.)
• Try popping up again after closing the relevant application
• If it still doesn't work, you can use "Disk Utility" to uninstall the disk: Open "Applications → Utility → Disk Utility", select Disk → click "Uninstall"

Try to use this trick as little as possible and only solve the problem of stuck if necessary.

Basically these methods are all. Although simple, what is often overlooked is: don’t plug and pull it out, and you should develop the habit of popping out first and then pulling out , so as to avoid data corruption or device errors.
