Default Mac .dmg Image Question

If I use MagicISO to convert a .dmg image into a standard .iso image, will it still be a bootable CD in the Mac? I ask because Ive been told that Mac CDs need to be written using a Mac to work properly.

Ive had this problem before, and ive ended up just burning the dmg file to a cd/dvd and loading it on my HacOS and running it from there

No good if you need it bootable though, so dont know the answer

A very good question indeed. I think, and I could be wrong, that unlike Windows CD's that need a boot.img file to be inserted somewhere, if the Mac CD has a System Folder on it then the OS should see it as being bootable.

I know some early macs were a bit funny in that they would not allow booting from copied CD-R's.

If you can get a .cdr rather than a .dmg it would better, as a .cdr was created using the "DVD/CD Master" option in Disk Utility on the Mac, and it's a clone of the media, plus I believe it's also just an iso file with a different extension.

From a very quick search, it seems .dmg files could be bootable too. You could have a look at dmg2iso and see if it's any good, or perhaps a copy of MacDrive, I'm sure there is a "burn Mac CD/DVD" option in there, if you give me a moment or two I'll reboot and have a peek.
