Well, I've not seen that one before. In fact I had to click on it so as to read the tiny
text, then it appeared in another window as a .png image... so I retyped it + also
supplied a .jpg of the same image of different size. Too wide: automatically scale.
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
...maybe this is large enough to see without clicking? It probably scaled small.
•About the actual topic in your reply, in regular size text:
{ did you upgrade from an older Mac OS X? from what?}
You mean it could not or would not boot SafeBoot?
Here's an official support topic page about it.
•OS X: What is Safe Boot, Safe Mode?

Could be you need to start from a boot volume, or Recovery partition to repair it.
That is a more detailed way to repair disk & repair disk permissions, unmounted.
Not sure about that SUID thing, though. It may revert after a normal startup.
Maybe someone can offer better 'ways & means'... LOL!
Good luck & happy computing! 🙂
