when I use Disk Utility to check permissions I get this statement at the end:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
What does this mean? What should I do?
IMac G5 Mac OS X (10.5) Not an intel G5
Do you use Apple Remote Desktop? If not, you can delete the offending file (ardagent.app). If you do use this file, you can reinstall with Pacifist, or a custom client install.
However, I think you can safely ignore this if it is causing no further problems.
