NIM Repair was designed for one purpose: to rectify situations where attempting to save changes made to NetInfo via NetInfo Manger results in the error "NetInfo write failed! (Operation succeeded)". Any changes that were made are lost and NetInfo reverts back to the previous state. The problem occurs when the permissions for NetInfo Manager, located inside the NetInfo Manager.app package, are altered. NIM Repair resets the file permissions back to the default setting and reactivates full functionality.
