DiskWarrior 5 supports any locally connected Mac OS Standard (HFS) or Mac OS Extended (HFS Plus) disk including Fusion Drives, RAID volumes, journaled disks, case-sensitive disks, FileVaults and Time Machine backups. DiskWarrior 5 supports both PowerPC and Intel Macs started in OS X 10.5.8 through 10.12.
Startup Disk Repair Requirements
DiskWarrior now ships on a bootable flash drive instead of DVD. If you plan to rebuild the directory of your startup (built-in) disk, you need to start up from another disk capable of starting up in OS X 10.5.8 through 10.12, 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 has OS X 10.4, 10.5 or 10.6 installed. 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.
To install, you must be started from OS X 10.5.8 through 10.12 with at least 1 GB RAM. More RAM may be required for large directories.
If you plan to rebuild a Fusion Drive, you'll need to run DiskWarrior while started from OS X 10.8.2 or later.
If you plan to rebuild a disk that is encrypted with FileVault 2, you'll need to run DiskWarrior while started from OS X 10.7 through 10.12. Alternatively, you can decrypt the disk and then run DiskWarrior.
If you wish to enable DiskWarrior's automatic hardware monitoring, you will need to install the DiskWarrior application on your Mac. To install the DiskWarrior application see the install requirements above.
Requirements for Older Macs
If you have older PowerPC-based Macs that are not capable of running OS X, DiskWarrior 2.1 is still available for purchase directly from Alsoft. Please contact our Technical Support Department to order.
DiskWarrior 4 version 4.4 is available, by request, on CD or DVD for old Macs that cannot run DiskWarrior from a flash drive. However, these CDs and DVDs cannot start up any currently shipping Macs models and can only be obtained by first contacting our Technical Support Department.
