Questions about Eject All Disks
How do I eject all drives at once on a Mac?
In Finder, select all drives on the desktop and press Command-E. Eject All Disks does the same from one button and includes disk images.
Why does my Mac say a disk can't be ejected because it's in use?
An app still has a file open on the drive. Quit apps that are using files from it, including Spotlight or backups in progress, and try again.
Is it bad to unplug a USB drive without ejecting it?
It can be. macOS may still be writing data, and pulling the drive can leave files incomplete or damage the disk's file system.
