When I click on a DMG file, finder opens and mounts it. Then I have to search for the new "disk" and select it.

Is there a way to open a DMG file and make finder select and show it automatically?

I don't want to create a DMG that does this. I want this behavior to be de default one for any DMG I download from the web.

    Strange, automatically opening and switching to the mounted DMG window has been the default behaviour for me for as long as I can remember.... not even sure how I would stop it doing that. (I'm still running Mojave, though, maybe that's changed in newer versions?)

  • I can't remember anytime it worked automatically like that for me. It is very annoying.

  • Out of curiosity, if you open Finder, right-click on a DMG, Open With... is DiskImageMounter there and shown as the default, or has something else possibly overwritten that?

    Having to search for it implies you don't have your disks showing on the desktop. They don't always open a window, but they always mount to the same spot on the desktop, just below any already-mounted disks.

    @Tetsujin AHAAAAAAAAAAA!!!! That's it. I enabled "show external disks on desktop" and now the DMG opens automatically! BRILLIANT. Please make your comment an answer, so I can accept.

Not all .dmg files open immediately to show their content in Finder [I think it depends entirely on whether they were open or not at creation/last Save], so if they don't, you need to have your Finder prefs set to show External disks. This will then show them to the right side of your desktop, below existing mounted partitions.

enter image description here

That way, if they don't auto-show, you can at least simply double-click them to open.
