Network Diagnostics won't close or force quit

Hi,

I'm new here so am hoping somebody can help me out?

Every time I use Network diagnostics it completes the check but wont close and just stays in my dock, force quit doesn't work and the only

way I can remove it is to force my mac to shutdown, which I know is not a great thing to keep doing. I've googled and haven't come up with anything useful. The only thing that has changed recently is that I've moved so am using a new broadband supplier, everything else seems to be working fine.

Any help VERY gratefully received.

iMac (27-inch, Late 2013), OS X El Capitan (10.11.5)

Hi, apologies if I'm being a bit dumb, but what do I do once it's in finder, I can't move it to trash because it's open?

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one. Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later. Isolating an issue by using another user account

First right click on network utility an option will be there - quit . click on it .

Or try to shut down the system from power button that is on extreme right corner of the computer i.e. next to F12 . keep on pressing the power button for 1.5 sec or press control + power button .

The screen will be black .

Close the lid and then again press the power button . the system will open with chime , enter user name & password then verify is the app still in dock .

Hi, thanks, but I've done what you suggest several times and Network Diagnostics does go after shutdown from power button/restart, but if I need the Network Diagnostics again the problem returns. I'm trying to find a solution that doesn't mean I have to shutdown to get it to quit as it should.

Yes it was hit and trial methods so it is wiser to take back up of all mails and data .it happens sometimes if system files or apps are corrupted then it is wiser to delete old user account and form a new user account .

And the last option is wipe out the hard drive and do a fresh installation .

this is the way to close wireless diagnostics external tool : Hold option key don't release it > click on wi fi icon on top menu bar > click on wireless diagnostics > quit on it , you are not closing the windows thats why it is showing three times in your dock .

close this window of screen shot

Well, next time I have to open the Diagnostics app again to battle with my continual lagging/dropped connections, I'll try that but I still don't see why it's suddenly started appearing multiple times when it never used to; and why you can't force quit it using any other other methods, and indeed, why you can't restart the computer and instead have to resort to a hard reboot.

...it's like the newly-insistent app is somehow not allowing the computer to restart normally, or shut the app down normally - just in the last few weeks or so. Even if I have suddenly developed the habit of not shutting the window down properly (although as usual, I simply click 'done' when it tells me my connection seems to working normally), then why can't I use any of the normal methods to shut these extra windows down?
