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)
