If you can’t eject a disk on Mac because an app is using it
You may not be able to eject a disk from your Mac if one or more apps are using it. In some cases, a warning message may identify the app that is using the disk. You can also press and hold the Command key and press Tab to see which apps are open and switch to a different app.
Quit the apps that are using the disk, then try to eject it again.
If you can’t quit an app, close the documents that are on the disk you want to eject, then try to eject the disk again.
Thanks for your feedback.
