The following applies only when running an installed copy of DiskWarrior and not when booted from the DiskWarrior flash drive or macOS Recovery.
10) Due to the ever enhancing security of macOS you might need to first "Allow" the system extension portion of DiskWarrior to be loaded on your Mac. The first time you launch DiskWarrior 5.2, the system extension might be blocked. You will only need to allow the system extension once.
Follow the instructions in the System Extension Blocked message to allow the DiskWarrior system extension software to be loaded. Open the Security & Privacy System Preference and click the lock and then click the Allow button.
Quit DiskWarrior, reboot your Mac and launch DiskWarrior again.
• What's in the works
The next major release of DiskWarrior will include the ability to rebuild APFS disks. Apple has recently released the APFS format documentation. Our developers are now using that documentation to update DiskWarrior to be able to safely rebuild APFS disks.
Using DiskWarrior Recovery Maker 1.3.
• What you need to know
1) DiskWarrior Recovery Maker 1.3 is compatible with macOS 10.14 Mojave. You will need DiskWarrior 5.2 to run DiskWarrior from a recovery flash drive created while running macOS 10.14 Mojave. Creating a 10.14 recovery flash drive will not allow DiskWarrior to rebuild APFS disks.
2) You need to take an extra step to create a DiskWarrior startup recovery flash drive on an iMac Pro, a mid-2018 MacBook Pro, late-2018 MacBook Air or a late-2018 Mac mini. Those 4 Macs are equipped with Secure Boot. By default, Secure Boot does not allow starting up from an external disk such as a DiskWarrior recovery flash drive. Also by default, Secure Boot prevents the creation of a macOS startup disk except for those created using Apple's Installer.
To create and use a DiskWarrior Recovery disk for Macs with Secure Boot, it will be necessary to change the default Secure Boot and External Boot settings using the Startup Security Utility. The Secure Boot setting will need to be changed to Medium Security or No Security. Alsoft recommends Medium Security. Additionally, the External Boot setting will need to be changed to Allow booting from external media.
Please follow the instructions found on Apple's web site using the following link to make the needed changes.
Notice: Creation of, or start up from, a DiskWarrior recovery flash drive will fail if the above steps are not taken.
