Using DiskWarrior 5.1 while started (booted) from macOS 10.13 High Sierra.
• What you need to know
1) DiskWarrior 5.1 is compatible with macOS 10.13 High Sierra.
2) Mac OS Extended (HFS Plus) disks can be rebuilt as before. This includes Fusion and Time Machine disks.
3) The internal Solid State Drives (SSDs) of Macs are automatically converted from Mac OS Extended (HFS Plus) to Apple File System (APFS) when upgrading to macOS 10.13 High Sierra.
4) Apple File System (APFS) disks are recognized by DiskWarrior 5.1 but are not able to be rebuilt. Click here to learn how to identify an APFS disk.
The following applies only when running an installed copy of DiskWarrior and not when booted from the DiskWarrior flash drive or macOS Recovery.
5) 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 5.1, 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 just released the APFS format documentation. Our developers are now using that documenation to update DiskWarrior to be able to safely rebuild APFS disks.
Using DiskWarrior Recovery Maker 1.2.
1) DiskWarrior Recovery Maker 1.2 is compatible with macOS 10.13 High Sierra. Creating a 10.13 recovery flash drive will not allow DiskWarrior to rebuild APFS disks.
2) The APFS Recovery Disk is now recognized and will show as a source from which to build a recovery disk.
