As described by the poster "If a GUI app runs as root, you've already got a problem, you say? Well, I said yeah, Cocoa and Carbon apps shouldn't be running as root, but this stuff does happen - badly written installers sometimes launch themselves as root, as do some utility programs, along with the popular lab management program 'iHook' - and it only takes one such screwup to allow hackers to root your computer. But no, they decided to flag it "Behaves Correctly" and ignore it." Running the command: osascript -e 'tell application "ARDAgent" to do shell script "whoami"' will allow root execution. The problem can be temporarily fixed by launching the Terminal and using this command: sudo chmod 755 /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent Also, don't repair permissions or it will undo the fix.
