[EB|#LOG:EXITBS:START], cannot boot to installer

[mrkcdl]

Describe the bug When I try to load the macOS installer with OpenCore, it gets stuck on the Apple logo screen with no loading bar. If I load in verbose mode, the last message before it gets stuck is [EB|#LOG:EXITBS:START]

Screenshots

Device (please complete the following information):

• macOS Version: Monterey, but same thing happens with Big Sur and Catalina
• EFI Version: 1.7.2
• EFI type (regular or HeliPort): regular
• T440p with i5-4300M and Nvidia graphics, 8GB RAM, 500GB WD Blue SATA SSD

Additional context I have tried everything from resetting my BIOS and configuring it according to the tutorial again, changing from com.apple.recovery.boot to two partitions, trying different SMBIOS configurations and even different macOS versions, the issue still persists.

Flip the values around to match older fw. See troubleshooting section.

EnableWriteUnprotector

Another issue may be that macOS is conflicting with the write protection from CR0 register, to resolve this we have 2 options: If your firmware supports MATs(2018+ firmwares): EnableWriteUnprotector -> False RebuildAppleMemoryMap -> True SyncRuntimePermissions -> True For older firmwares: EnableWriteUnprotector -> True RebuildAppleMemoryMap -> False SyncRuntimePermissions -> False
