Hello,
This is my first topic here, so I hope it follows all the rules. I'm using an AMD FX 6300 with the /amd1 kernel.
Notice: This guide is now obsolete, although it can be still useful if you wanna replace a kernel by hand. Download the new Yosemite here: Hackintosh Yosemite
A warning
Before you proceed following this guide be warned that I am not responsible for any damages to you or your hackintosh installation.
What you need
A working hackintosh installation
Yosemite 10.10.1 Update package
Installation disk (see How to Install Yosemite on Your PC guide)
The guide
Copy your current kernel to "/Users/kernel". This can be done using the following command in Terminal (you have to enter your password when executing this command):
sudo cp /System/Library/Kernels/kernel /Users/kernel
Take note of your volume name (you can use Disk Utility for this). The name of my partition is "Yosemite"
Download the Yosemite 10.10.1 Update package and open "OSXUpd10.10.1.pkg".
Follow all the installation steps and finish the installation by pressing "Restart".
Instead of booting from your hard drive, boot from the installation disk.
Enter the correct startup options for your processor (for example /amd if you're using an AMD processor).
After the setup started correctly, select your language and after that use "Utilities -> Terminal" to open the terminal.
Copy the kernel you saved in /Users to your /System/Library/Kernels directory, you can use the following command for this:
cp -f /Volumes/"Yosemite"/Users/kernel /Volumes/"Yosemite"/System/Library/Kernels/kernel
Make sure to replace "Yosemite" with your volume name.
After this run the following commands (still replacing "Yosemite" with your volume name):
rm -rf /Volumes/"Yosemite"/System/Library/Caches
kextcache -u /Volumes/"Yosemite"
Restart your system, removing the installation disk.
After you restarted, you have to follow a small wizard and after that, you installed Yosemite 10.10.1!
Hopefully, this is useful for some of you,
Mr. eXoDia.
