Svarar själv efter att ha hittat detta på apples diskussionsforum:
"The message "ACL found, but not expected" does not indicate an error. It just says that additional security settings have been established for the central Applications and Library folders after the first install phase of the operating system was completed. Those settings are intended by Apple and they make sure that users accessing the system volume via the file sharing feature of Leopard cannot intentionally or unintentionally remove components from those folders. When you remove those ACLs, you are destroying this security feature.
An additional problem is that "Repair permissions" currently cannot re-establish those settings after they have been removed. So you end up with an installation that has broken permission settings which can only be repaired manually."
Det är alltså inget att bry sig om Bosse!
