I have been playing around with the ViewView Options in Finder and I must have touched something crtitcal because now whenever I click on a folder in Finder it automounts a disk image located on my external hard drive. The image is located in /Volumes/elements/App/myapp.dmg.

If I unplug the external hard drive, everything is back to normal. But when the external hard drive is connected, it happens again.

I could remove the file, but I want to find a better solution.

Edit: It does not matter if I move the dmg to another location (i.e: I move it to /Users/charasoverride/app.dmg), it gets automounted as well.

Update: It does not happen for every folder but it does for sidebar items. (Favourites, Devices, etc.)

  • Can you be more specific about what causes the issue you're describing?

  • In finder, i click any folder then the dmg gets automounted, this only happens when my usb disk is connected because the offending dmg is located there, if i remove the usb it does not occur nor get any error.

  • So, for example, if you have a .dmg file located in /Volumes/elements/App and you click on a folder in ~/Desktop, the .dmg mounts itself?

  • that's right, but it just happens for that specific dmg, not for all dmgs, i mean i can have more dmg in the folder and they wont get automounted

  • I couldn't help but notice that the path you outlined above (/Volumes/elements/App/myapp.dmg) included "elements." This external drive wouldn't happen to be a Western Digital brand drive, would it?

I would suggest trying two things. As a disclaimer, I have no idea what could be causing this because it makes no sense. These are just some basic Finder troubleshooting steps:

Suggestion 1:

  1. Open Terminal from /Applications/Utilities

  2. Run the command killall Finder

  3. Log out of your user account and log back in

  4. Try again

Suggestion 2:

  1. Open Finder

  2. Navigate to ~/Library/Preferences

  3. Move the files com.apple.finder.plist and com.apple.finder.plist.lockfile to the Desktop

  4. Log out of your user account and log back in

  5. Try again

If neither of these suggestions work, I don't know what else you could try. Other StackExchangers?

  • Thanks for the suggestion but none of these worked.

  • Update: It does not happens for every folder, only for the items in the sidebar (Favourites / Devices, etc..) it is really anoying because it takes a few seconds until it gets mounted not displaying the folder contents until the dmg is up.

This would be the semi-nuclear options but you could trash the entire contents of ~/Library/Preferences except for perhaps com.apple.mail.* (if you use Apple Mail.app) and com.apple.Safari.* Also delete everything in ~/Library/Caches

The full Nuclear option would be to delete almost everything in ~/Library except ~/Library/Mail, ~/Library/Safari, ~/Library/Application Support.

And don't forget to restart after trying those troubleshooting steps.
