How to burn multiple sessions on a CD
Today Apple’s Pro Tips web page carries a hint
that was news to me. It tells you how to use Mac OS X’s built-in Disk Utility to burn multiple sessions on a single CD or DVD.
It describes how to create a burn folder, open Disk Utility, select “Image from folder” from the New option in the File menu, then highlight the new image, select burn and then — here’s the magic part — make sure that the expanded options (blue arrow button in top right) are showing in the next dialog.
Check the “Leave disc appendable” option:

Then you will be able to append further burn sessions to the same disk by following this process at each burn.
A bit of a pain in the butt perhaps, but it saves discs, saves money and saves the environment.

it would be great if they could build this feature right into the Finder. Like if you make a Burn-folder and you click the ‘burn’ button, it would ask you if you’d like to leave the disc appendable or not.

I agree. This process outlined above isn’t a glowing example for an OS that “just works”.

These steps don’t appear to work for DVDs — leave disc appendable is grayed out.
