Fix for slower startup and shutdown times since Snow Leopard 10.6.1

Ever since I upgraded to Snow Leopard 10.6.1, my MacBook Pro startup and shutdown was much slower than before.

I searched for a quite a while on forums to find the solution, but nobody seemed to know a solution. I finally figured out what it was. It seems that somehow the ownership of my startup volume's root directory (/) wasn't assigned to the root account anymore, but to my account instead. This made the kernel prelinking fail since it requires that root is the owner.

This is how you solve this after launching the Terminal app:

sudo chown root:admin /
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches

You'll have to enter your password after the first command.

Hope this helps someone, since it was really frustrating to have these slower startup/shutdown times for me.

Good work in finding that. M-Audio's M-box re-assigned my permissions and I think this fixed it.

How do you run the initial test to identify whether the ownership of my startup volume's root directory (/) is NOT assigned to the root account anymore, but to my account instead? I don't want to try your fix and potentially cause add'l system problems if it isn't applicable. Thank you in advance.

Hi Jimbo,

Open a terminal and write this (it lists the contents of your top-level hard disk directory without finder hiding stuff):

sudo ls -al /

You'll see something like:

oak:~ gbevin$ ls -al /
total 37220
drwxrwxr-x 38 root admin 1360 Nov 19 16:56 .
...

The line with the single dot should say 'root admin', if it doesn't, you need to execute the instructions in the post.

Take care,

Geert

Probably because you typed the '/' wrong or something.

CI silently went away and I never heard from them anymore after I made a fuzz about it on the internet and refused to talk to them. I had to close the comments on those posts since there was too much spam going on :/

Thanks for caring!
