Information/Books/Sources to learn the technical site of Hackintosh/IOS/AMD Kernel Development to become a developerBy Hawxxer
do you know where someone could start getting involved in development for Hackintosh / IOS (jailbreaks etc.) development? I am searching for information about the Kernel development rather than developing apps.
I recently finished my bachelor of engineering in electric engineering but the computer science always interested me more. We are being tought about some principles of a operation systems and writing code in c..
Until know I found the apple developer website, and the books from Jonathan Levin (but they are some kind of expensive for my current situation as a student).
I also think that it would be useful to get started with the structure of the linux kernel.
Do you have more sources I could learn more? How did you become what you are know in the hackintosh community?
Google is not very helpful "Hackintosh development" only brings up how to develop apps with an hackintosh...
I posted it in AMD because I am especially interested in the kernel manipulation to get the XNU Kernel working under AMD. If this is the wrong corner, please move it in the right one.
And for sure other sources are the wikis of insanelymac and the other hackintosh websites!
FINALLY IT'S WORKING THANKS TO @insanelymac
But i have a single problem, My graphic card Radeon x1950 Pro not working, It used to work good on Snow Leopard but now its not on Yosemite i don't know why ... any kext needed ??
Here the kext used to work good for me on Snow Leopard
Any Help ?
How to create a macOS Installer which doesn't need bootloader kext injection (FakeSMC in pre-linked kernel), bypass High Sierra firmware and MBR checkBy fusion71au
This is a brief guide on how to create a vanilla El Capitan (also same process for Sierra) OS X Installer USB with an updated prelinked kernel containing FakeSMC.
It is tailored for those users who want to understand the “nuts and bolts” of how to create an installer and also to help brush up on their terminal skills (rather than have one made for them with the numerous automated “tools” available or even Apple’s createinstallmedia) :
Specifically, it is also a “Proof of Concept” which shows that installation is possible without even having to rely on boot loader kext injection.
Existing Yosemite installation (or Mavericks - see post#4 for steps 7,8) “Install OS X El Capitan.app" downloaded to the Applications folder Pacifist FakeSMC.kext - Slice or Kozlek branch Bootloader - Clover or Chameleon 8GB or larger USB drive (16GB recommended), formatted HFS+ (MBR or GUID) named “Installer”
1. Boot into Yosemite with the kext-dev-mode=1 boot flag
2. Open OS X terminal and type the following lines, followed by <Enter> after each line.
The image restore and file copying may take a while to complete, and at the end of the process, the Installer volume is renamed to “OS X Base System"....
sudo -s hdiutil attach /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/SharedSupport/InstallESD.dmg asr restore -source /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg -target /Volumes/Installer -erase -format HFS+ -noprompt -noverify rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages cp -av /Volumes/OS\ X\ Install\ ESD/Packages /Volumes/OS\ X\ Base\ System/System/Installation cp -av /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg /Volumes/OS\ X\ Install\ ESD/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System diskutil unmount /Volumes/OS\ X\ Install\ ESD exit 3. Right click on the “OS X Base System” Volume and click “Get Info”
4. Click on the lock icon and untick “Ignore ownership on this volume”
5. Extract/Copy the El Capitan Kernels folder into /System/Library/ of the USB with Pacifist. NB It is found in the "Essentials.pkg" in /System/Installation/Packages
6. Delete or Rename the original /System/Library/PrelinkedKernels/prelinkedkernel —> OG.prelinkedkernel
7. Copy FakeSMC.kext and other necessary kexts (e.g. VoodooPS2Controller.kext for laptops) into the /Library/Extensions folder of the installer USB using Finder.
8. Back in terminal, type the following lines, followed by <Enter> after each line to rebuild the prelinkedkernel…..
sudo -s chmod -R 755 /Volumes/OS\ X\ Base\ System/Library/Extensions chown -R 0:0 /Volumes/OS\ X\ Base\ System/Library/Extensions touch /Volumes/OS\ X\ Base\ System/System/Library/Extensions kextcache -u /Volumes/OS\ X\ Base\ System exit Any errors should be noted but the output below is normal e.g.
9. Install your Bootloader targeting the OS X Base System volume
10. Boot your system with the USB without injected kexts into the OS X Installer GUI....
The original prelinked kernel in a fresh install of El Capitan will also lack FakeSMC ie it will only be linked to Apple signed kexts. In order to boot into El Capitan the first time around without boot loader kext injection, the PLK needs to be rebuilt for the El Capitan volume like we did for the installer:
1. Boot into Yosemite with the kext-dev-mode=1 boot flag
2. Delete or Rename the original /System/Library/PrelinkedKernels/prelinkedkernel for the El Capitan volume —> OG.prelinkedkernel
3. Copy FakeSMC.kext and other necessary kexts (e.g. VoodooPS2Controller.kext for laptops) into the /Library/Extensions folder of El Capitan using Finder
4. Back in terminal, type the following lines, followed by <Enter> after each line to rebuild the prelinkedkernel. In this example, the El Capitan volume is named "El_Capitan" - change if you have named it something else...
sudo -s chmod -R 755 /Volumes/El_Capitan/Library/Extensions chown -R 0:0 /Volumes/El_Capitan/Library/Extensions touch /Volumes/El_Capitan/System/Library/Extensions kextcache -u /Volumes/El_Capitan exit 5. Install your Bootloader targeting the El Capitan volume. This step is only necessary if you are installing El Capitan on a new drive without existing boot loader (not required if installing on a disk with existing boot loader beside Yosemite).
6. Reboot your system without injected kexts into El Capitan!

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. macOS High Sierra bypass Firmware and MBR checks in post#13.
