FireWolf OS X PE 9: Troubleshoot

FireWolf OS X PE is created upon macOS Recovery, providing native support for accessing files on HFS/APFS formatted partitions. Applications and maintenance kits embedded in PE provide you a chance to transfer personal files, restoring from backups, repairing disk permissions and more when your main system won’t boot. https://pe.firewolf.app/

1. Restore the @800MB "Boot.FireWolf.OS.X.PE.9*.dmg" using DiskUtility to 8-16GB USB Pendrive, but got "Recovery Image verification fail" upon boot. So, what I've done to make it boot up (on USB):

• Go to /com.apple.recovery.boot/ then rename "Boot.FireWolf.OS.X.PE.9.ProPlus-Zlib.dmg" to "BaseSystem.dmg"
• Edit "com.apple.Boot.plist" with:

<dict>

<key>Kernel Cache</key>

<string>\com.apple.recovery.boot\prelinkedkernel</string>

<key>Kernel Flags</key>

<string>rp=file:///com.apple.recovery.boot/BaseSystem.dmg</string>

</dict>

2. My downloaded dmg version is w/o Clover included, so before restoring using DU, I need to fully erased my USB using GUID, then manually installing Clover as well as my worked EFI folder plus 10.13 kexts to USB-ESP (RecHD version used is from macOS High Sierra 10.13.5) << I just use FakeSMC & PS2Controller kexts

3. You could using Etcher.app https://etcher.io/ for restoring it to USB as well, but ur PenDrive size becomes exactly same as dmg image (there's no option restoring to Internal storage partition with Etcher, compared to Disk Utility #afaik).

4. Recovery environment from USB is damn slow for accessing some included apps << this is known issue bcoz no QE/CI graphics enabled (don't imagine for gaming or watching HD movies under Live PE #LoL). But, this PE is usefull enough for maintenance tasks (at least if you're familiar with Hiren's Boot CD or DLCBoot with Windows PE).

Enjoy and Happy Hackintosh! :)
