How to Eject Disk Images in Finder (and How to Fix It)

by - – Your Mac may still be using the DMG, even though you no longer do. When your computer doesn’t do what you want it to, it’s annoying. There are times when it is frustrating to be faced with an error message: “The disk couldn’t be ejected since the Finder is currently utilizing it.” What are you planning to do with it?

If you’re unable to eject your DMG, there’s usually a straightforward reason for this.

Why is it so difficult to remove your DMG?

A DMG, also known as an Apple Disk Image, is similar to a digital drive in that it allows you to download and install software from a hard disk or USB flash drive.

Downloading a program from the web often results in a DMG file being downloaded instead. Afterwards, you’ll get the standard box asking you to copy the software to your Applications folder so that it may be installed on your computer. Afterwards, you remove the DMG because it is no longer required.

This error, on the other hand, might be perplexing and frustrating when you encounter it. This DMG is useless, and no one wants to look at it.

A DMG that won’t eject is most likely because you didn’t copy the app to your computer. By double-clicking on the app in the DMG, you’re launching the program from the DMG’s own installation directory itself. Since you can launch apps from DMGs and Finder won’t eject the DMG because it is currently in use, it is likely that the software functioned fine. Before you can eject the DMG, you have to close the software that is causing the issue.

It’s best to copy the application to your Applications folder before ejecting a DMG file if you intend to use it on your computer. To get back to the app, you’ll have to eject it.

If the DMG won’t eject, restart your Mac. Restarting your Mac will sometimes resolve issues with the DMG, allowing you to remove the disc.

Similar problems arise with hard drives

Ejecting hard disks can also be affected by the same problem. Actively running a program from a drive will prohibit you from ejecting the drive, whether it’s a hard drive, USB drive, or a physical disk.

However, it isn’t always clear which program is taking advantage of the drive’s resources or executing on it. Quitting any open apps that don’t show a connection to the hard drive may be worthwhile in this scenario.

One of the best ways to find files and apps on your Mac is using Spotlight. However, this feature might be a pain because it works in the background, indexing your drives to keep track of what’s where. You may not know that Spotlight is indexing the drive you’re trying to eject, so if you try to eject it, it may appear as if there is no reason why macOS would block you from doing so.

You can go to System Preferences > Spotlight > Privacy if you want to stop Spotlight from indexing your drive so you know it won’t be the cause of your ejection problem. The (+) button allows you to select a linked drive.
