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? – Matt Love Mar 15 '12 at 20:38
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. – spacebiker Mar 15 '12 at 20:42
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? – Matt Love Mar 15 '12 at 20:43
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 – spacebiker Mar 15 '12 at 20:45
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? – soxman Mar 16 '12 at 3:07

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 and 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. – spacebiker Mar 15 '12 at 21:02
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. – spacebiker Mar 15 '12 at 21:43

This would be the semi-nuclear options but you could trash the entire contents of ~/Library/Preferences except for perhaps* (if you use Apple and* 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.
