Mac users running Mac OS 9.x are very enthusiastic about Apple's iTunes and Disc Burner applications. However, since Disc Burner cannot easily burn bootable CDs (unless a disk image of a bootable disk has been previously created) and iTunes cannot burn CDs in DAO (disk-at-once) mode, it is still necessary to keep Roxio's Toast CD-burning software for these purposes — and in most cases it is impossible to keep all of the files necessary to run all of these applications active at the same time. It is very annoying to switch back and forth between sets of extensions using Extensions Manager or Conflict Catcher and then rebooting just to change CD-burning applications.

I have written an AppleScript application for this purpose that makes rebooting unnecessary if the CD burner is a USB burner (though it is still required that the CD burner be turned off and then back on). If you are still using a USB CD burner with Mac OS 9.x, you may find it useful. It's called USB CD Burner Toggle 1.0, and it can be downloaded here.

NOTE: If you have Roxio's Toast Titanium 5.x, this workaround is not necessary.

Renato Brazioli has kindly contributed an Italian localization of this utility. (That is to say, the dialogs are still in English, but the folder names and other parts of the system that are different in Italian than those in the English version of the OS have been changed in the script for compatibility with the Italian version of Mac OS 9x.)
