How to create a macOS Installer which doesn't need bootloader kext injection (FakeSMC in pre-linked kernel), bypass High Sierra firmware and MBR check

Try downloading it from here (instead of from the App Store):

Please post back here if it works.

Hi,

The link works but this file won't work. After installing and rebooting you will get a notification that "Some updates were not installed".

I downloaded the full 10.13.1 app and recreate the USB installer using "macOS High Sierra Patcher" app from http://dosdude1.com/highsierra/.

Updates for Sierra and High Sierra

Custom Prelinkedkernel Generator Tool

I have made a custom prelinkedkernel generator "PLK.tool" for Sierra + El Capitan. Instructions:

1. Download and extract the attached BaseSystem_PLK.tool.zip into your ~/Downloads folder.

2. Copy any extra kexts necessary for booting your hack to ~/Downloads/BaseSystem/ExtraKexts (e.g. FakeSMC, VoodooPS2Controller), making sure SIP is disabled.

3. Copy BaseSystem.dmg to ~/Downloads/BaseSystem

4. Open terminal and run the following commands...
cd ~/Downloads/BaseSystem
chmod +x PLK.tool
./PLK.tool
---> supply your admin password ---> will place your new custom prelinkedkernel on the desktop.

Hi, i followed guide above, but for Mojave. And i cant get wifi work in installer mojave. This is my terminal: is it wrong?

Unfortunately to generate a working prelinked kernel for Mojave, the PLK tool needs to be run in Mojave (with Mojave's kextcache binary), otherwise you see the errors about the missing dependencies.

Try the prelinked Mojave kernel that I have already posted here Mojave and AirPortAtheros40.kext.

no, i ran above code inside Mojave and got error. Also tried your kernel attached, no lucky

Thanks. I successful to enable wifi at the first time. But after step 1, next boot screen to setup else, I realized wifi still off, did you get the same?

Yes. On first boot to the newly installed Mojave on your hard dive, AirPortAtheros40.kext will be absent in /System/Library/Extensions. Copy the kext into /S/L/E and rebuild kext caches/prelinkedkernel eg

In terminal...

sudo cp -R AirPortAtheros40.kext /System/Library/Extensions
sudo chown -R 0:0 /System/Library/Extensions/AirPortAtheros40.kext && sudo chmod -R 755 /System/Library/Extensions/AirPortAtheros40.kext
sudo touch /System/Library/Extensions && sudo kextcache -u /

then reboot your system. Your Atheros wifi should now work.

Confirm the kext has loaded by typing kextstat | grep Atheros. I get the result

Mac-Pro:~ fusion71au$ kextstat | grep Atheros
   67    0 0xffffff7f81df4000 0x148000   0x148000   com.apple.driver.AirPort.Atheros40 (700.74.5) 9753F22E-5C85-3E95-B543-0870CF03838A <66 15 12 7 5 4 3 1>

Hi, how to open terminal to run these commands at first boot, sir? At the first time boot from partition installed Mojave, it only show like this
And I realized GUI from boot APFS and HFS patched is different: on APFS boot installer, I can touch safari, time machine. AndHFS installer: none. Anyone same

The prelinkedkernel used by the installer is not the read only file inside BaseSystem.dmg. It is in a hidden folder (unhide with ShowAllFiles.app), full path is /Volumes/Install\ macOS\ Mojave/System/Library/PrelinkedKernels/prelinkedkernel...

The terminal app for the installer can be opened by clicking on the Utilities Menu at the top. However, easier for noob to continue installation on the hard drive (click "My computer does not connect to the internet") ---> set up the new user, then install AirPortAtheros40.kext through terminal or kext utility ---> reboot and wifi can now be set up.

Those on Mojave who wish to run an older Mac OS X, e.g El Capitan, using the above method,their is a way to Install and run using your CURRENT Clover config.plist.

I currently use iMac18,3 in Mojave/El Capitan

Secret is copying PlatformSupport.plist to /S/L/CoreServices in BOTH Installer and Installed.

Copying to Installer requires customizing BaseSystem.dmg, probably for advanced users.

I can use same kexts in both as well.
