DiskWarrior now ships on a flash drive instead of DVD. If you plan to rebuild the directory of your startup disk, you need to start up from another disk capable of starting up in OS X 10.5.8 Leopard through 10.14 Mojave, such as the DiskWarrior Recovery flash drive or your Mac's OS X Recovery (the Recovery HD). OS X Recovery is available in OS X 10.7 (Lion) and later.
The DiskWarrior Recovery flash drive ships with the ability to start up any Intel Mac that currently starts up in OS X 10.4 Tiger, 10.5 Leopard or 10.6 Snow Leopard. If you have a newer Intel Mac, you can use the included DiskWarrior Recovery Maker to update the DiskWarrior Recovery flash drive to start up your newer Mac.
