System/Library/Extensions Doesn't Exist

[Morteo]

Hello,

This is my first install of iDeneb 1.3.

After install, I'm looking at the "No HPETs available" and "Package 0 didn't get an HPET" errors. I've read all over that I should remove the "AppleIntelCPUPowerManagement.kext" file, located in "System/Library/Extensions", but "System/Library/Extensions" does not exist. There is no Extensions folder. "Extensions.mkext" exists, but there is no directory. When I try to remove the Extensions.mkext file, it says that the drive is read-only and I can't delete the file.

Where is the AppleIntelCPUPowerManagement.kext file?

Thanks!

mkext file is just an archive, it contains everything that's used by your system from Extensions folder. You can edit it with this tool :

Mkext Tool

and see if the kext is there. Also check in System Profiler if the AppleIntel - kext is loaded. If not, the problem is something else. Mkext Tool can also unpack the mkext package for you to recreate the folder with all the kexts.

I apologize but I don't quite understand your instructions. When I boot the computer, the Apple logo appears with the rotating icon, and after a while I'm presented with "You need to restart your computer." When I boot the computer using the "-s" flag, I see a console telling me that "Package 0 didn't get an HPET"

When you say "Also check in System Profiler if the AppleIntel - kext is loaded", I don't understand how to view the System Profiler. All I have is a command prompt.

Thanks for the quick reply!

I understand now. I thought you could boot normally.

Ok, so if you want to make any changes on the disk - first, you have to mount the drive. At the prompt write :

mount -uw /

and return. Now you can remove the mkext file, but if you dont have extension folder - it probably wont recreate itself. To unpack the mkext package and see what's inside, or recreate the folder :

mkextunpack -d output_dir file_you_want_to_unpack

hope this will help.

Okay, I decided to wipe the drive and start again. This time around there is an Extensions folder, and there's no HPET problem.

Now I have another problem. When I start the system normally it still tells me to restart. When I boot with the -s flag, I'm presented with a lot of "family specific matching fails" errors and a "panic". At this point it shows me a big error and stops working. What should I do now? Would you like a screenshot of the exact error?

Thanks again for all the help.
