It is also a good idea to backup both your Extensions folder and your kernel once you get a working system. You could then boot into Single User Mode (-s) and manually replace those kexts.
To backup your Extensions folder:
1. First we will make a directory called "backup" in our root directory to store them. Open Terminal and type:
2. Copy your kexts to the new "backup" folder.
Code:
cp -r /System/Library/Extensions /backup
To backup your kernel:
1. Open Terminal and type the following:
Code:
cp -r /mach_kernel /mach_kernel.backup
Now if your kernel gets replaced you can boot using the boot-option mach_kernel.backup and it will load your backup kernel.
