MediaEraser is a simple utility for erasing optical media (CD-RW and DVD-RW) on OS X using the OS X Disc Recording framework. It doesn’t do anything you can’t do with Apple’s Disk Utility or Roxio’s Toast, but it’s much simpler to use. This version supports Intel Macs, from OS X 10.6 Snow Leopard through OS X 10.9 Mavericks
