10.3: Repair a disk mount problem after 10.3.1 upgrade System
I bought an iBook with OS X 10.3 and upgraded it to 10.3.1. After the upgrade, I could not mount disk images from my hard drive or burn CDs. Apparently this is a common problem after upgrading. I phoned AppleCare and this is what they had me do:
  1. Run /Applications/Utilities/Disk Utility.
  2. Click on "Macintosh HD� in the left column and then press the "Repair Disk Permissions� button. I don't think this step was part of the solution to my problem.
  3. Delete the file called /System/Library/Extension.kextcache
  4. Delete the folder called /System/Library/Caches/com.apple.kernalcaches/
  5. Restart
After these steps, disk images mount properly and the CD burner works.

I am unable to delete: /System/Library/Extension.kextcache
It says I don't have permission, though I am the admin.What am I doing wrong?

I found that disabiling Jouraling seems to fix the mounting problem

In 10.3, you should be able to delete any file as an admin user. It will ask you to "authenticate" and you will be able to carry out that action.

I know that I should be able to delete the file but couldn't. Don't know why.

Thanks, that worked great! Although, I'm kinda curious as to what that actually did? I've been hearing its some kinda verification code problem?

This worked well for me in 10.4.9 -- thanks! I had to change the paths, though. One way to delete them is to open Terminal.app and enter:

sudo rm /System/Library/Extensions.kextcache
sudo rm -rf /System/Library/Caches/com.apple.kernelcaches/

I've tried deleting the files mentioned to fix the problem of not being able to mount disk images, but I can't find them. There's no Extensions folder in my library and the com.apple.kernalcaches file does not exist in the cache folder. Help????

*censored*ing ace!

No my PowerBook won't start at all, and all I get is a hughe forbidden sign in stead of the upstart.

Anyone who actually knows what they're talking about who has a solution here? What the heck do I do now?!!

Pop in your OS X DVD, restart while holding down the C key, and once you get to the Installer, do an "Archive and Install". That is, assuming you are still running 10.3, as this hint is for 10.3.x, and NOT newer versions of OS X.

If you are running a newer version of OS X, the method for clearing out the kextcache is considerably different; it's best to let a utility like Onyx take care of it for you.
