10.6.3 update issues

Here's a link to Apple Support that lists many of the permissions messages that can be ignored:

agree with Doc & silvarios on this one.

Fixing permissions isn't the fix. It's probably more beneficial to do a safe boot and flush the caches.

These two files, Extensions.mkext and Extensions.kextcache can get corrupted by rogue installs. They're both used @ startup to get the correct Kernel Extensions loaded.

To force rebuild these caches, both files are deleted. There are FREE utilities available to perform this task; OSX86Tools is just one .
Terminal Commands used are:
”sudo rm -rf /System/Library/Extensions.mkext”
and
“sudo rm -rf /System/Library/Extensions.kextcache”

WILL YOU PEOPLE STOP REPAIRING PERMISSIONS!

It does almost nothing.

Boot from your install disc, repair the DISK with the Disk Utility and then report back.

guitarist,
No, I think Doc is correct. Repairing permissions does not do what people seem to think it does.

I for one have never Repaired Permissions during the past 6 years. I had seen where it was recommended after an update, but I just never did. I've had no problems.

The permissions situation has gotten progressively better with newer versions of the OS. In the early days of OS X it was a complete mess. But even with 10.6.3 there can still be a couple things wrong after an update, depending on what extras you install.

A minor permissions problem with iTunes or Flash won't be the end of the world. But repairing permissions certainly is not going to hurt anything and it might even help.
