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.

As noted, files don't magically reappear after being deleted, DMG files or not.

Install EtreCheck and post the report. Allow Full Disk Access.

Use the Additional Text icon to paste in the report.

Confirm they are the image files and not the mounted disk?

I don’t think this can happen with it in the Trash, but if you mount the image and drag the app into the Dock, when you click on the app icon in the Dock, it will mount the disk from the image.

You might avoid a trip to the Genius Bar if you post the EtreCheck report. It may reveal the source of the problem.

When you're in EtreCheck, click on "Share Report", then Copy Report, then paste it into your reply using the Additional test icon.

.dmg files are just disk image files. They don't move or replicate themselves.

If a .dmg file isn't opened up and mounted, and you have permissions to delete it, you should be able to drag it to the Trash and empty the Trash. If that doesn't work, there may be some application on your Mac which is actively replacing the .dmg files. What application would do this? To me, that would be a potential cause of concern.

Those are mounted DMG files.

It is not normal for .dmg files to come back again.

Even if Google Chrome or Capture One 22 wanted to maintain local copies of their .dmg installers – which I don't think they would – why would they place them on the Desktop, instead of out of the way in some folder?

Something does not add up.

Click the eject button next to their respective names in the Finder sidebar. Then delete the files from what I assume is the Downloads folder.

here it isn't. :)

+1 That will teach me for taking a post literally. :)
