R7500v2 Using the Netgear app on iMac

I am happy with my Netgear dual Freq router. I live in a community that built its own Internet access for residents. 1GB. I get about 970MB down and 980 UP. 

My qyuestion is about the Netgear app that I can use to monitor the router, change setting, i.e. manage it remotely. I am using it on a cable connected ethernet  connection to my router, and the app comes up when I reboot. I really don't need it in the background and whenever I try to exit the app gracefully by clicking on the icon on the upper bar, and selecting exit. It brings up a screen that asks if I really want to exit. I click YES. It never goes away. I finally have to "FORCE QUIT" to remove it. Anyone else know a better way?

iMac running OS X El Capitan 10.11.6.
