You don't actually need any add-on software at all to burn CDs in Mac OS X. You can just drag files and folders onto the icon of a blank CD, as described on Section 8.7.2.
If you want fancier featuresrecording less common disc formats, for examplewhat you need is Toast for the Macintosh. It comes from the same company that makes Easy CD Creator.
Its main rival is DiScribe (www.charismac.com). Both programs can create audio CDs, video CDs, data DVDs, and so on. Both come with a program that helps you turn old vinyl records and tapes into digital CDs, too.
The only disappointment: Neither program can treat a CD as a glorified floppy disk, as Easy CD Creator for Windows can, so that you can add and delete files freely (rather than burning the CD all at once).
There's a workaround, though: Copy the contents of a rewriteable CD (a CD-RW disc) to a folder on your desktop; make whatever changes you like to the contents of this folder; and then burn the CD-RW again. (Use the Disk Utility program in your Applications Utilities folder to erase the disc first.)
