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:
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.
