If You Are Purchasing a DiskWarrior Upgrade
The upgrade is not available for download. All orders will be shipped a DiskWarrior DVD via US Mail. Please allow one to two weeks for delivery of your DVD.

To install, DiskWarrior 4 requires that your Mac start up in Mac OS X 10.3.9 through 10.5.x. This is a change from version 3 of DiskWarrior which supported older versions of Mac OS X.

DiskWarrior 4 version 4.1 is available, by request, on CD for old Macs that do not have DVD drives. However, these CDs cannot start up any currently shipping Macs models and can only be obtained by first contacting our Technical Support Department.

Note: DiskWarrior DVD revision 904 is now shipping with DiskWarrior 4 version 4.1. All Intel and PPC Mac models introduced as of 03/03/2009 and meeting the system requirements for DiskWarrior can be started from the DiskWarrior DVD. The current DiskWarrior DVD cannot start up the new 13" and 15" MacBook Pro (SD card slot) models introduced in June 2009. An updated disc that will also start up these recent Mac models will be released as soon as Apple, Inc. releases new startup files to Alsoft, Inc. and other developers.
