About This File
Patched OSInstaller.framework to allow macOS 10.12 installation on MBR partition.
To use those patched files you must follow HowTo-10.12.x to create an USB installer. You can't just run the app downloaded from Mac App Store.
The patch is made base on 落下爱@pcbeta 10.10.x patch method
How to make 10.12 installer for MBR?
Open Install macOS Sierra.app/Contents/SharedSupport/InstallESD.dmg/BaseSystem.dmg first.
1. Restore BaseSystem.dmg to HFS partition and rename the partition’s name as macOSMBR as /Volumes/macOSMBR/
2. Copy InstallESD.dmg/BaseSystem.dmg to /Volumes/macOSMBR/
3. Copy InstallESD.dmg/BaseSystem.chunklist to /Volumes/macOSMBR/
4. Copy InstallESD.dmg/AppleDiagnostics.dmg to /Volumes/macOSMBR/
5. Copy InstallESD.dmg/AppleDiagnostics.chunklist to /Volumes/macOSMBR/
6. Remove /Volumes/macOSMBR/System/Installation/Packages
7. Copy InstallESD.dmg/Packages to /Volumes/macOSMBR/System/Installation/Packages
8.OSInstaller replace to
/Volumes/macOSMBR/System/Library/PrivateFrameworks/OSInstaller.framework/Versions/A/OSInstaller
9. Copy InstallESD.dmg/Packages/Essentials.pkg/System/Library/Kernels/kernel
to /Volumes/macOSMBR/System/Library/Kernels/kernel
(use Pacifist v3.2.14 to access the contents of Essentials.pkg, and make directory /System/Library/Kernels first.)
(Need kernel only if you use Chameleon with -f to boot the installer disk, needn't with Clover.)
10. Boot to /Volumes/macOSMBR/ to install macOS.
And, need a /Extra/SMBIOS.plist supported with /Volumes/macOSMBR/System/Library/CoreServices/PlatformSupport.plist.
Set a SMBIOS with Chameleon Wizard.
Work fine with Enoch r2839+
and /Extra/kernel.plist with
<key>KernelBooter_kexts</key>
<string>Yes</string>
