This does the same thing as:
hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/savefile
but neither that nor this makes an ISO9660 *filesystem*... they both are still Mac OS Extended (HFS+). I can use neither resulting image on WinXP!! Crap... to the person who asked about .dmg, you can't just rename those b/c they are compressed. If you make a .cdr ("CD/DVD master") and rename it .iso, that will burn in Windoze programs, but the damn volume is still hfs+ and therefore not readable when you put the disc in a PC optical drive. I typed "man hdiutil" and there is a "filesystem -iso" but I can't figure out where to put it in the command b/c I think Apple changed the hdiutil syntax. :(

Okay, at least in 10.4.10 these are the same:

hdiutil convert /path/to/filename.dmg -format UDTO -o /path/to/outfile
and
hdiutil convert -format UDTO -o /path/to/outfile /path/to/filename.dmg

DMG Converter (http://sunsky3s.s41.xrea.com/dmgconverter/index.html) can create ISO filesystems. But it cannot CONVERT images to ISO filesystems, only make new images using it. But the Terminal command "hdiutil" can with the "makehybrid" verb. Open Terminal and type "man hdiutil" to see this; tap space bar or return to get down to VERBS (specifically convert and makehybrid). The syntax is:
hdiutil makehybrid -o [options]
[options] are -hfs, -iso, -joliet, and -udf. So first drag a .dmg to your Desktop. Then open Terminal and type:
hdiutil makehybrid -o ~/Desktop/[new_image_name] ~/Desktop/[source]
and hit Enter. [source] can either be a directory or a disk image. So if you mount the image first and THEN use DMG Converter, "converting" and "making" a new disc image from the mounted volume is the same thing... But the nice thing about the hdiutil Terminal command is that "By default, if no filesystem is specified, the image will be created with all four filesystems as a hybrid image." So don't specify -hfs, -iso, -joliet or -udf and your image has all 4 filesystems! I tried it on a 458 MB .dmg and got a hybrid .iso that was 530 MB in size. Compared to the 592 MB ".iso" file that was actually a .cdr made with "hdiutil convert" -- and only had the single HFS+ filesystem -- I'm much happier w/ the true ISO that is 60 MB smaller and has 4 filesystems! I'm beginning to like UNIX more and more... BTW Damage Isolation DOES make .ISO images which can be burned using Sonic, etc. and other windoze apps, but just beware that the burned CD has only an HFS+ filesystem.

Just out of curiousity, how is this any different from running
hdiutil convert -format UDTO -o myisofile, dragging the DMG onto Terminal hitting return and then changing the CDR extension to ISO?

Actually it's no different. However most of us are not proficient (or even familiar) with the Terminal which makes this drag and drop app just perfect.

Very easy. Just drag the DMG file onto the app, and it will quickly convert it into an ISO file.

The name for this program is brilliant. I love it.

5 stars all the way.

extremely useful if you want to send your disk image to a windows user. but if your only going to use your image on a mac, stick with dmg - its more functional, at least on the mac os. program works fine and is very fast.

BTW, the program appears to be a droplet. you simply drag and drog your dmg on top of the program.

It won't work in 10.2, just as a FYI.

Downloading it just to view the Readme.txt is worth it. Oh, works as expected.

I think you are talking about Toast image disks (Roxio) that the extension .toast can be changed to .iso. But DMG image disks are different.

I always thought that you can convert .dmg to .iso by just renaming it...

Nope.

I guess that command is pretty much all this program does, but hey, it's helpful!

Strange I created a DMG in MS-DOS format and then used Damge Isolation. I get a file with the extension .iso.cdr that I rename as .iso, but it won't be accepted by Windows XP (inside Parallels).

I tried the same thing and it worked for me. Did you rename it properly (from the Get Info window) or just hide the .cdr extension?
