I burn ISO images on my Mac fairly frequently, but not often enough to have the process committed to memory. In the past I’ve always followed the instructions I found in a macosxhints post. It works, but it has always seemed a little convoluted to me. I found a much simpler method today:
- Insert a blank CD/DVD.
- In Finder, double-click on the ISO image you want to burn.
- Open Disk Utility (in Finder / Applications / Utilities / Disk Utility). Depending on your settings, either of the previous steps might open Disk Utility for you.
- In the left pane of Disk Utility, select the ISO image (e.g. “7.2-RELEASE-i386-disc1.iso”, not the “FreeBSD_Install” contents of it).
- Click the Burn icon on the top of the window (or Apple-B on the keyboard, or via the menu select Images / Burn ).
- Open Disk Utility (in Finder / Applications / Utilities / Disk Utility).
- Make sure nothing is selected in the left pane of Disk Utility (in case you had it open already).
- From the menu, select Images / Burn (or Apple-B on the keyboard).
- A file requester will pop up. Navigate to the ISO image you wish to burn.
- Insert a blank CD/DVD if you haven’t done so already.
- Click Burn.
Note, too, that double-clicking an ISO file in the Finder will mount it just like any other (write-only) disk image. Once it’s mounted, it’ll be listed in the left pane in Disk Utility; selecting it will activate the Burn button, at which point you can proceed from step 5 of your instructions.
