Sierra 10.12 MBR

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

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
(don't need patched OSInstall.mpkg since pb4)

If you want to patch MBR by yourself, here is the patch code, works on 10.12.0~10.12.6

perl -pi -e "s|\x48\x8B\x78\x28\x48\x85\xFF\x0F\x84\x91\x00\x00\x00\x48|\x48\x8B\x78\x28\x48\x85\xFF\x90\xE9\x91\x00\x00\x00\x48|g" OSInstaller
codesign -f -s - OSInstaller

do you have the untouched dmg and can you upload the md5 for the untouched dmg?

Install 10.12 Developer Preview[Evad3rs.net].dmg md5=3635505ec428b062fadb15c63c14e95e

10.12.db1.16A201w InstallESD.dmg md5= 7fab60441894b64acdc20729a07c37a4
