Is Apple that busy that they put code signatures to wrong place? I was absolutely amazed that dozens of files were indeed at wrong place and print theraphy fixed it. Unfortunately, Mac blogs&support sites are busy with Snow Leopard so I didn't hear about it too.

Having no code signature is one thing (very common), having a tampered (in OS eyes) code signature is another. It would really matter in case you granted access to your printer application in Leopard firewall...

Anyway, thanks to this expensive (!) utility, I am aware of it and first time in my life, I am off to download&reinstall Leopard 'combo' update 10.5.8. Who knows what else they missed?

ps: Don't let 'repair permissions' fool you, OS X doesn't touch a bit of home permissions which really matters to Printers and pro apps like Adobe stuff. It is not the same as the OS X permission repair.
