Creating ISO in OS X Leopard
I’ve been trying to find how to create iso image using my OS X Leopard and I’m in vague whether iso or OS X Leopard is not “standard” enough in the industry.
My search was in a dead end in desperate I hit on Wikipedia and found this,
ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR.
That’s quite enlightening. Why OS X use other file extention instead? So perplexing.
It’s quite easy to create the .CDR a.k.a .ISO using OS X Leopard built in Disk Utility. Here is the steps,
- Slide in your disk to the drive.
- Fire up your Disk Utility *type in your spotlight search for faster access, on top right most lup icon*, you should see the mounted disk on the left pane.
- Hilight the disk on the left pane *some disk may have two level, the Session number and the disk name. Hilight the Session number*
- Click the New Image on top windows icon
- Change the image format to “DVD/CD master” and save.
- When finished, rename .CDR to .ISO.
- Double click to open and mount it to test whether it’s working

This way you can create bootable .ISO from bootable disk. Pretty useful when playing in virtualization. Enjoy.
