Hi guys! My disk utility app is corrupted. It show the error: Dyld Error Message:Library not loaded: /System/Library/PrivateFrameworks/GraphKit.framework/Versions/A/GraphKit I googled it, but I only got the advise to re-install, or use Pacifist to get just Disk Utility from the disk. Problem is: my brother left the install disk inside a laptop he then got repaired, so the disk is gone.. Is there any other way I can get this app back? Thanks a lot in advance!
