3) Mac OS Extended (HFS Plus) disks can be rebuilt as before.
4) The Startup Disk of Macs are automatically converted from Mac OS Extended (HFS Plus) to Apple File System (APFS) when installing or upgrading to macOS 10.14 Mojave, macOS 10.15 Catalina or macOS 11.0 Big Sur. Only internal SSD drives are converted to APFS by macOS 10.13 High Sierra.
5) External drives are not automatically converted to Apple File System (APFS). Your Mac OS Extended external drives can be rebuilt as before.
6) DiskWarrior 5.2 is compatible with macOS 10.13 High Sierra, macOS 10.14 Mojave, macOS 10.15 Catalina and macOS 11.0 Big Sur when rebuilding Mac OS Extended external drives.
7) DiskWarrior 5.2 now runs within macOS 10.14 Mojave and macOS 10.15 Catalina Recovery.
8) The Preview application in DiskWarrior can now copy files to APFS disks when recovering data from a failing Mac OS Extended (HFS Plus) disk.
9) Numerous minor updates were made to accommodate additional security measures in macOS 10.14 Mojave and macOS 10.15 Catalina.
10) To rebuild Time Machine disks in macOS 10.14 Mojave, macOS 10.15 Catalina and macOS 11.0 Big Sur, DiskWarrior must be given “Full Disk Access” from within System Preferences. Otherwise, they can be be rebuilt from macOS Recovery or the DiskWarrior Recovery flash drive. Starting with macOS 11.0 Big Sur, Time Machine disks can be formatted as APFS and cannot be rebuilt. Mac OS Extended (HFS Plus) Time Machine disks can be rebuilt under Big Sur.
The following applies only when running an installed copy of DiskWarrior from within macOS 10.13 High Sierra, macOS 10.14 Mojave, 10.15 Catalina and 11 Big Sur; not when booted from the DiskWarrior flash drive or macOS Recovery.
11) 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 (DiskWarrior 6.0) will include the ability to rebuild APFS disks. Apple released a majority of the APFS format documentation in June of 2020 . Our developers are now using this documentation to update DiskWarrior in order to safely rebuild Apple File System (APFS) disks.
Using DiskWarrior Recovery Maker 1.4.
What you need to know
1) DiskWarrior Recovery Maker 1.4 is compatible with macOS 10.14 Mojave and macOS 10.15 Catalina. You will need DiskWarrior 5.2 to run DiskWarrior from a recovery flash drive created while running macOS 10.14 Mojave or macOS 10.15 Catalina. Creating a 10.14 or 10.15 recovery flash drive will not allow DiskWarrior to rebuild APFS (Apple File System) disks.
2) An extra step is needed to create a DiskWarrior startup recovery flash drive on an iMac Pro, late 2019 Mac Pro, a mid-2018/2019 MacBook Pro, late-2018 / mid-2019 MacBook Air or a late-2018 Mac mini. These 4 Macs are equipped with Secure Boot via Apple’s T2 Security Chip. 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.
