Re: hdiutil help
Yes, I understand what is happening and why (now), but I think for most noob's MacOSX should have treated ISO images differently when you click on one and then click on the Burn to Disc button. It just does not seem to be as intuitive as it should be for users that are not as smart as you are (or I am now). ;-) I agree, the Finder should be smart enough to recognize a burnable image like that and just do the right thing. Bruce, I know I'm very late to this party, but why not use -fs UDF? I tried this and got an error from hdiutil, but I was able to mount the image with Disk Utility and it shows up as a UDF disk image in CMD-I. Windows should be able to handle UDF properly, no? Error was: mount_udf: mount_udf: open /dev/disk3 failed, Resource busy: Resource busy /sbin/mount failed with error 256 However, the resulting image mounted properly as a UDF image.

Re: hdiutil help
Isn't it because the ISO should an CD-ROM format, such as Rockridge, or Joliet, or ISO 9660, and not a file format that is used on hard drives? I have created many useless CD-R drink coasters while trying to burn an ISO to a CD-R disc, because MacOSX often mistakenly asks if I want to burn the Contents of the ISO image to the CD-R, instead of burning the ISO image on to the CD-R and I forget that doing it that way does not create a CD-ROM that can be read on other computers. When I use OSX's Disk Utility and burn the ISO image to the CD-R, I get a CD-ROM that can be read on any computer. Hope this helps.

Re: hdiutil help
Hello: First you must tell us your configuration. I suppose you are writing a script with Applescript. And you are using a virtual environment. Is that correct? I am retired and I had some time helping you. Here is a link to convert a zip file to an ISO file readable by mac. I found it using google.com. I had to register to brainsurface.com to take a look at the article. http://www.brainsurface.com/how-to-convert-downloaded-zip-files-into-iso-files-for-use-as-virtual-cddvd-roms Break a leg!!
