In MacOS X, how do I prevent a folder with extension .theme being treated as a package?

Solution 1:

iDVD's Info.plist defines the file type and that it's a package. Therefore, you need to get rid of it, or edit the Info.plist. Since the latter is likely a major pain, and you don't use it anyway, remove it.


Uninstall iDVD (if possible), or delete the iDVD application bundle.


Then either rebuild the launch services database by entering the following in Terminal:

/System/Library/Frameworks/CoreServices.framework/Frameworks/\
LaunchServices.framework/Versions/A/Support/lsregister
-kill -r -domain local -domain system -domain user

or restart your machine.
