Override 670MB size limit on Finder-burned CDs

If you use the Finder to burn CDs, it (rather arbitrarily) sets the size of the image used to stage the CD to 670MB. If you have 700MB CDs (which are very common), you will waste 30MB by using Finder. If you'd rather use all the available space, follow these steps. You can also use this to burn many copies of something, while only having to prep the files once -- a big time saver.

  1. Make a new folder and put all your stuff in it you want to burn.
  2. Open the Terminal and go to the folder containing the folder you just populated.
  3. Type: hdiutil makehybrid -o somename your_folder
  4. Look in your current folder, and you should see a file called somefile.iso.
  5. Check the size of this file and make sure it will really fit on the CD.
  6. Type hdiutil burn somefile.iso, or use Disk Utility to burn it. If you want to make more copies of this CD, repeat this step for as many CDs as you want.
