So you’ve just exported some photos from iPhoto and you want to burn them (or any files) onto a CD or DVD. Your Mac makes this easy. Here’s how.
To copy files onto a blank disc, you can just drag folders and files onto the blank disc icon on your Dock. But if you want to watch your progress filling up the disc (CD or DVD), then open the blank disc in the Finder so you can see the available space shrink as you drag files onto the disc.
