My 2017 iMac is connected directly to the router via ethernet cable and I leave the wifi on the computer turned off as the ethernet connection is faster than my wifi. I have other wifi only devices around the house so I have not shut off wifi at the router. I have one application on my computer, a game, that somehow turns the computer's wifi to 'on' every time I launch the game. How is this possible and how do I stop this app from turning on the wifi? I guess it's not a big deal, just something that makes you go Hmmm and scratch your head.
