manual patching

While the patcher is excellent, open-source documentation can be valuable. The following steps, derived from discussion on the MacRumors thread, are for 10.14.5 on a mid-2010 MacBook. Many parts apply to other systems.


Retrieve and open the Packages folder from a Mojave InstallESD.dmg.
pkgutil --expand OSInstall.mpkg Expanded

Open the Distribution file in a text editor.
Insert return true; at the beginning of the installationCheck() function.
Remove installsOS=true from the top of the file.

pkgutil --flatten Expanded Patched.mpkg
Install the patched package to an empty HFS+ partition.

make bootable and set kernel flags

Open the freshly installed volume.
Copy /usr/standalone/i386/boot.efi to /System/Library/CoreServices/.
Open /Library/Preferences/SystemConfiguration/ in a text editor.
Change Kernel Flags to -v -no_compat_check keepsyms=1.

prevent kernel panic on Penryn CPUs

Delete /System/Library/UserEventPlugins/

fix sound

Replace /System/Library/Extensions/AppleHDA.kext from macOS 10.13.6.

install GPU detection kexts

Copy from macOS 10.13.6:
/System/Library/Extensions/NVDAResmanTesla.kext /System/Library/Extensions/NVDANV50HalTesla.kext

fix VSLGestalt missing symbol

Install @parrotgeek1's NDRVShim.kext.

Or, replace from 10.13.6:
/System/Library/Extensions/IONDRVSupport.kext /System/Library/Extensions/IOGraphicsFamily.kext
(prevents AppleGraphicsDevicePolicy from loading)

Or, patch NVDAResmanTesla.kext's main binary:
0x1ea59a - 0x1ea5b3: nop
Then, open the patched binary in a text editor and find+replace VSLGestalt to IOLockLock or any other known symbol of the same length.

enable framebuffer

Copy from 10.13.6:
/System/Library/Extensions/GeForceTesla.kext /System/Library/Extensions/GeForceGA.bundle
