Update, 1 Sept 06: The steps below work only for CDs, but not for DVDs. See discussion in the comments section below.
Click on images to see larger-sized pictures:
1) Find and start the Disk Utility application. Look in the “Applications” -> Utilities folder
2) Create a new Image: File -> New -> Disk Image from Folder
3) Select the folder with the files to be copied, then click on the “Image” button. NOTE: Only folders can be copied, not individual files. Each time you want to copy the file, you might want to create a new folder and place the file in that folder.
4) IMPORTANT STEP: Select “read/ write” for Image Format (if not, the CD or DVD will be closed). Click on “Save”.
5) Wait while the Image (.dmg file) is being created.
6) Once the image is created, you’ll see this screen. Select the image from the Disk Utility window and click the “Burn” icon.
7) Insert the CD/ DVD. If this is a brand new disk, you will see this dialog box. IMPORTANT – select “Leave disc appendable” if you want multisession burning later on. Then click “Burn”.
8) Wait while the files are being copied to the CD/ DVD.
9) Follow steps 1 to 8 the next time you want to copy to the disk. When you reach step 7 and insert the previously recorded disk, you will see this dialog box. The difference is that now you see the “Append” button instead of “Burn”. IMPORTANT — Remember to select “Leave disc appendable” before clicking Append.
