Dmg files

Got it.

Any way to get them off my desktop? Or are they meant to just be there in perpetuity?

I think Barney-15E nailed it.

When you drag an application into the Dock, you're not actually copying the application into the Dock. You're just creating a reference that says "Go access this file at its original location."

If

• That original location was on a mounted disk image
• The disk image is not currently mounted
• The disk image file is still available

then the system will helpfully re-mount the disk image when you try to access the file.

I take advantage of this for some documents that I keep in an encrypted .DMG file.

What you need to do to stop this happening is to

• Install Chrome and Capture One 22 in your Applications folder (if they aren't there already). You might have to run an installer, or it might be as easy as dragging-and-dropping the application icon from the mounted .DMG volume to the Applications folder on your startup drive. Usually it will be obvious which.
• Drag the Chrome and Capture One 22 icons out of your Dock, dropping them anywhere else. This will not get rid of the applications – just the old shortcuts that point to the applications on the .DMGs.
• Drag the Chrome and Capture One 22 icons from the Applications folder on your startup disk to the Dock.

Now you can unmount the .DMG volumes and they will not keep re-appearing whenever you run the programs. You can also trash the .DMG files if you like, though my personal preference is to save .DMG installation kits in case I ever need to reinstall the program in question. Either way, the .DMGs will be out of your hair.
