Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent” has been modified and will not be repaired.

That message means that the current software is installed. It's not a cause for concern.

I have no idea what your answer means but here are the steps I followed to figure out how to make this stupid error go away.

This error happened after I updated to the latest RDA from Apple. To track it down I did the following:

1. Clean install of OS X 10.9.1
2. Run "Repair Disk Permissions" - Nothing found
3. Update iTunes to latest (and theoretically greatest)
4. Run "Repair Disk Permissions" - Nothing found
5. Update iBooks (another great piece of work)
6. Run "Repair Disk Permissions" - Nothing found
7. Update Remote Desktop Admin.
8. Run "Repair Disk Permissions" - Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.
9. Run "Repair Disk Permissions" - Same results
10. Go to System/Library/CoreServices/RemoteManagement
11. Rename RemoteManagement RemoteManagement-Bak
12. Run "Repair Disk Permissions" - Nothing found (I did not reboot after renaming the directory so if the file is active (and it doesn't show up in Activity Monitor, so I'm not overly convinced that it is), why did it not give me the same error message?

Now, I don't want to jump to conclusions here, but I somehow think the problem is in the RDA upgrade. I never had that error message before (starting with 10.7) but I had it after the upgrade.

Oh, as a side note: Before I renamed that directory and made the error message go away, I booted into single user mode and ran Disk Utility and had the exact same error message. I then booted from a USB install drive and ran Disk Utility once again, same results. Now if this error is caused because the file is open, why did it not show up on the first run of "Repair Disk Permissions"before I did the updates? Why did it only show up after the RDA update was performed? I may not be Einstein, but I know that 2+2=3.9999999 more or less...and this is a RDA update = error message.

Sorry to sound stupid but what does RDA stand for? Thanks. I got the same error message when I ran repair disk utility & I'm having awful trouble with my iphoto app since it upgraded itself at the beginning of December. I've now given up on ever seeing it in action again. and have run out of ideas on how to mend it. After almost 20 years with all things Mac, and always been able to sort out software issues, I am now stumped!

This is just a Date/Device/OS X update, basically to say the problem still exists and Apple are doing nothing to rectify it. They say buy AppleCare I say "AppleDoesn'tCare" - it's a waste of money in terms of software support, I've got dozens of bugs on 2 x iMacs, 2 x iPads, 2 x iPhones, 1 x iPod Touch , 3 x Apple TV's and 2 x Airport Time Capsules and Apple has absolutely no interest in fixing them.
