    I'm trying to create a hybrid disk image that parallels can use and found that the following code in terminal works for some:

    hdiutil makehybrid sourcefile.cdr -o sourcefile.iso

    However, verbose mode reveals that the process hangs at "Creating hybrid image..." and then results in the following error:

    hdiutil: makehybrid failed - operation not permitted

    Any ideas what's going on?

    Let me ask a different question: How do you convert a .cdr file created with Disk Utility into a hybrid ISO recognizable by other operating systems?

    Had the same problem.
    - Add sudo to the beginning of the command "sudo hdiutil makehybrid -iso -joliet -o destinationFile.iso SourceFile.cdr". this will execute the command as root
    - When prompted for password, enter your current user logon password (Not the root user password). This fixed the problem for me.
