I am trying to install macOS Tahoe on an AMD Hackintosh and I am stuck at a consistent early boot failure during installer loading.
Hardware
Gigabyte X570 AORUS Master
Ryzen 9 3900XT
AMD RX 580
OpenCore latest build
NVMe and USB installer recreated multiple times
Problem
Boot reaches OpenCore picker, installer starts, then fails during early Apple secure boot and recovery stage.
Error shown in log
EB RH PF usr standalone OS.dmg.root_hash
EB LD OFS OPEN Err 0xE usr standalone OS.dmg.root_hash
EB RH LRH Err 0xE
EB BST FBS Err 0xE
Also seen
x86legacyap.im4m
BootKernelExtensions.kc.development
Failure happens before macOS kernel loads
What I already tried
Recreated USB installer multiple times using different tools
Tried USB 2.0 and USB 3.0 ports
Reset NVRAM multiple times
BIOS settings checked, Secure Boot disabled, Above 4G decoding enabled
Different OpenCore config variations
Config notes
SMBIOS MacPro7,1
SecureBootModel Disabled
APFS EnableJumpstart tested both enabled and disabled
AMD kernel patches applied for Ryzen 3000
Issue happens before kexts matter because kernel does not load
What I suspect
Issue is related to macOS Tahoe installer root hash validation or Apple secure boot trust chain involving im4m files or a development installer build. Same error happens on recovery and full installer methods.
What I need help with
Has anyone fixed this exact error
OS.dmg.root_hash x86legacyap.im4m Err 0xE
on AMD Ryzen systems like X570 or Ryzen 3000
Looking for confirmed working OpenCore settings for Tahoe or a known working installer build that avoids this issue or any workaround to bypass this validation stage.
