I just created a DMG and threw some folders in it. If I double-click a folder it opens in a new Finder window each time. Folders outside of the DMG are still opening normally. Holding option when I double-click causes the former window to close, but it's pretty inconvenient. Does anyone know how to get a DMG to show up in a normal Finder shell?

This is what I'm seeing, for what it's worth:

  • I hope someone has a hidden preference to enable this since the Finder and DiskImageMounter clearly want to make a new window when it first mounts a dmg. I poked a bit at hdiutil imageinfo file.dmg on several images to see if there were a field that could be set to suppress this, but nothing looks promising.

There are many things that could be going wrong here. First of all, make sure that when you navigate to Finder > Preferences > General, the option "Always open folders in a new window" is unchecked. If not, there are many solutions to your problem listed below:

  • Naviate to View > Show Toolbar
  • Navigate to View > as List, as Columns, or as Cover Flow
  • Get TotalFinder (http://totalfinder.binaryage.com/), which adds many more settings to Finder

Good luck!
