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



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





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

I was able to proceed with installation by adding new system information using a tool.


then it booted with USB installer and installed Sierra till next 45 mins. 


However when it rebooted on first time with Sierra then it showed error that Voodo Rehabman PS2 kext is not loaded and my USB mouse, Keyboard didn't work.

Neither attached PS2 Keyboard & Mouse.


I put the Voodo Rehabman release kext of Dec 2016 into S/L/E of newly installed Mac Sierra. 

And Since then I am stuck  at
