Patched OSInstall.mpkg and OSInstaller.framework to allow OS X 10.12 installation on MBR partition.

To use those patched files you must create an USB installer. You can't just run the app downloaded from Mac App Store.

After creating the installer, copy those files like that:

OSInstall.mpkg to /System/Installation/Packages

OSInstaller to /System/Library/PrivateFrameworks/OSInstaller.framework/Versions/A

The patch is made base on 落下爱@pcbeta 10.10.x patch method

How to make installer for MBR.

Open Install 10.12 Developer http://ift.tt/1UrUS4Y first.
1. Restore BaseSystem.dmg to HFS partition and rename the partition’s name as OSXMBR as /Volumes/OSXMBR/
2. Copy http://ift.tt/1q3z3XQ to /Volumes/OSXMBR/
3. Copy http://ift.tt/1kHJ7qj to /Volumes/OSXMBR/
4. Copy http://ift.tt/1Uhg4Jz to /Volumes/OSXMBR/
5. Copy http://ift.tt/1UrVQ14 to /Volumes/OSXMBR/
6. Remove /Volumes/OSXMBR/System/Installation/Packages
7. Copy http://ift.tt/1kHJ7qn to /Volumes/OSXMBR/System/Installation/Packages

8.
OSInstall.mpkg replace to
/Volumes/OSXMBR/System/Installation/Packages/OSInstall.mpkg

OSInstaller replace to
/Volumes/OSXMBR/System/Library/PrivateFrameworks/OSInstaller.framework/Versions/A/OSInstaller

9. Copy http://ift.tt/1fiEcf5
to /Volumes/OSXMBR/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/OSXMBR/ to install Mac OS X.
Is it really as easy as the steps outlined above... [►source]
