If your Mac fails to start up from the DiskWarrior DVD, it's likely the version of Mac OS X on the DVD does not support your newer Mac. If your wireless mouse is not working in the Startup Manager, use the right- or left-arrow keys to choose the DVD, and then press the 'Return' key to continue starting up. This will bring up the Startup Manager which will allow you to choose the DVD as a startup disk. Instead of pressing the 'C' key immediately upon start up (step 3 above), press the 'Option' key. Some newer Macs with wireless keyboards have timing issues when starting up from any DVD. Starting Mac OS X from a DVD is a lot slower than from the internal hard drive. The 'C' must be pressed before the end of the startup 'chime.'
Insert the DiskWarrior DVD into your Mac and wait for the disc to appear on your Desktop.
