Disk Utility will not (or cannot) repair an issue

I ran Disk Utility repair from safe start-up because when my Mac shuts down, it gets to a gray screen where there is spinning spokes and this will not shut off until I press the "restart" button on the back of computer.

When Disk Utility ran repair disk, it stated that it would not repair

Warning: SUIDfile:System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Mac OS/ARDAgent has been modified and will not be repaired.

Could this possibly be causing the shut down issue? Does the mac need to be taken in for repairs or should I re-install OS X??

iMac (21.5-inch, Late 2012), OS X Yosemite (10.10.4)

You are not alone but it's a OS X oddity. Apple does not explain this. AFAIK

No problem to let this as it is. Trying to remediate this is not recommended

I'm sorry I just gave you the good news

The bad ones are: I have had the same problem as yours ( a permanent spinning wheel at shutdown during 15 minutes) 15 days ago without any other way to stop that but forcing the shutdown process by using the power button on the iMac.

Since I have got many other problems occurring which explain my presence here.

copy past actions don't work. System UI server errors & User Notification Center errors

Whithout an AppleCare Advisor help, I'll have probably to reinstall Mavericks.

I'm afraid !

Unfortunately the previous poster is not correct.

In order to repair the startup volume you cannot do so from the startup volume!

Please restart from the Recovery Partition by holding down Command + R and open Disk Utility. Then attempt to Repair the HD. If the drive shows errors after the 2-3rd attempt, then you know he HD is damaged and should be replaced. Contact your local Apple Store or AASP to have it replaced. If the machine is covered by AppleCare still please contact them first, they will run some diagnostics with you and if the machine still fails will advise on the next step. If the machine is covered by AppleCare any repairs will be at no charge.

I did not say anything about the use of Disk Utility from the startup volume... 😕

That is correct and that is the mistake you made. You instructed the OP to run DU from the startup volume, Repair Disk cannot be run on the same volume as it is logged into.
