Extensions have wrong permissions_Corrupt System

I am trying to see how to fix the permissions on my computer. I have ran the fix permissions from the Disk Utility until it says everything is fine. I have even booted from a Snow Leopard disk to run fix persmissions and repair disk. Still having the same problem.

The problem is, that in the finder I still keep getting errors saying extension "x" could not be used because it was not installed correctly. The computer crashed while doing an update so I believe this to be what caused the problem. I have way to many applications to have to reinstall each one. I have the old extension folders for the Library and System (that I know are fine) but cannot figure out what to boot from that will show the old finder so I can replace them (and I obviously cannot replace them on an active system). Unfortuately all my latest TimeMachine BU have the corrupt system now too. I want to update to Lion but not with a corrupt system. Please help.

Mac Pro 2.66 Dual Intel 13GB RAM, Mac OS X (10.6.4), iPhoto 8.0.3, iTunes 10, iPhone 3GS 8G

I always advise to always have bootable backups (clone) on hand; to update your backup clone (takes 10 minutes) before making changes.

With a clone, you never would need to reinstall anything.

And keep some backups off line. ALL Tm backups?

If you were to upgrade to lion the best policy there is a clean install on another hard drive anyway, not over the old system, and then use Setup Assistant. Not sure other than being forced due to AppStore and iPhones that Lion on our MacPro1,1 is desirable.

You could try the 10.6.8 combo. Your profile says you were using 10.6.4, and only 10.6.8+ would get all the recent security udates, updates you need and want, and weeks behind on.

I assume you tried Safe Boot and repair the hard drive in the process. Now to just get into using Carbon Copy Cloner too and maybe use there on half one of your backup drives.

Thought I was safe with TimeMachine backup but it wrote over the good system before I knew something was wrong.

Yes I am using 10.6.8 but it would not let me update the information (ran last update about 2 weeks ago).

Unfortunately I have been using mobileme for years and I am forced to upgrade to Lion in order to keep all my things synced correctly. I have the iPhone, iPad, and iPods-so Apple pretty much has me over a barrel and I have to move to iCloud (which means upgrading to Lion).

Unfortunately I do not have another drive I can install Lion on. I have not tried safe boot-what do I benefit from by doing this when booting from a CD and repairing did not seem to help.

Thanks for your help-I will wait for you comments

You need a drive or three. WD 1TB Black $119 / WD 10k VR 250GB $150 (200MB/sec) / WD Green 2TB $119. check the reiews on that new 10K VR.

You could shrink or use one of those corrupt backup drives for clones and system images for instance.

I use to: clone, repair the clone, apply the update to the clone (use to be able to apply those updates to a drive different from boot drive; also, to apply updates to sparse disk images to keep those current).

An emergency boot volume for maintenace is or use to be a must - small handy 30GB with just Apple OS, fit anywheres.

Probably it's a third-party kernel extension. Disk Utility won't fix that.

Those, and all other commercial "utilities" for the Mac, are worthless if you have adequate backups. I suggest you get rid of them.

You still haven't told us what the error message is.

One of the errors is; The system extension "System/Library/Extensions/"XX".kext" was installed improperly and cannot be used. Please try reinstalling it or contact the product's vendor for an update.

These just keep coming up the same error just different file each time

Do a favor, do a clean install of the system and then use Setup Assistant.

I bought TTPro a decade ago and keep it updated just to have around. And it use to find one or two things, do things DU and other utilities do not.

Setup a special emergency and maintenance only boot drive that has the utilities you need but don't install on your work system.

Is there a way to do a clean install with the new Lion installer? Used to be a way to select Options and tell the installer what type of install you want to do. I created an Lion Install disk and do not see this option anymore. IDEAS??

Give an example of what "XX" is. It makes a big difference whether XX is a built-in component or one that you installed.
