Tutorial on recovering from bad kext install

[chasingcharlie]

I -- unfortunate -- installed a ps2 extension that has rendered my system useless because I get the grey, restart screen. The old extension is in a backup directory.

Can someone please tell me how to recover from this? A step-by-step, either in terminal, or starting in another mode (or using external program to access HFS plus files) on how to restore the old kext?

 

thanks

e-mail me personally, a quick message for whatever. I really need this ...

 

thanks

use the search function

 

use a install disc to boot from if you can't boot in single user mode (-s switch)

[hecker]

Boot in single user mode by entering "-s" at the darwin boot manager prompt.

Once the system has loaded, you have to mount your main OS X drive (simply enter the commands you get on the screen, right at the end).

Then, you can remove any unwanted kexts by entering:

rm -R /System/Library/Extensions/the_problem_kext_file
rm /System/Library/Extensions.mkext
reboot

 

You have to, of course, make sure that you enter the target file's name EXACTLY as it is. If you are unsure of what the file name is, you can make a directory listing by entering:

ls -la | less /System/Library/Extensions/*

(make sure you type in the last "/")

 

Do not ask me to give you detailed explenations on how to use the console (aka. "The Terminal"). You can find that out by googling.

 

Good luck!
