The scenario is this: I have four to six applications running with at least five windows open on my screen. I get an update or find a nice interesting app to install. I download the app and then click on the .dmg file to mount it. In most cases a small window opens after .dmg file has mounted.

Click-drag to the Applications folder to install. And when done, time to unmount the disk image. There are three methods that a commonly use when ejecting a mounted .dmg file. These are (in order of preference):

  1. Open a Finder window, then click on the eject icon next to the mounted disk image.
  2. Eject 3

  3. Right-click on the mounted .dmg file on the desktop and select ‘Eject “[name of disk image]“‘.
  4. Eject 1

  5. Click-drag the mounted disk image to Trash icon on the Dock (the Trash icon changes into the Eject icon this is done).
  6. Eject 2

All of the above methods work fine but I often find it a bit of a hassle to have to open a Finder window or use Exposé to reveal my desktop. I feel there’s an extra step or two that’s unnecessary.

But a few days ago, I discovered another way to ejecting a mounted disk image. (“Doh!” moment for me.)

I mentioned that most (if not all) disk image or .dmg files, when mounted, would open a small window where you can see the app and an alias of your Application folder. So all you need to do to install is click the app and drag it to the Application folder alias.

What I’ve just figured out is that the small icon at the bottom-left corner of the just opened window can be used to eject the disk image.  Just right-click on the icon and select ‘Eject “[name of disk image]“‘. Boom!

Eject 4

I know, I know. It’s trivial but at least now I can eject disk images in just two steps. Yay.
