aldopec Posted September 17, 2018 Share Posted September 17, 2018 Hello. When the system turns the display off after inactivity (unsure if that is called sleep) some weird things start happening. 1) Usbs turn off and on intermittently (I can see that from my keyboard) 2) Wifi does not work (I have a program running and it loses connection) 3) fans stop and start intermittently (the most annoying! It sounds like when it first boots up every 10 seconds or so) I am not sure why it is happening, although I can return back from it with no problems whatsoever. I have a GTX 970, i5 6600 and ASUS Z170 P. Link to comment https://www.insanelymac.com/forum/topic/335557-sleep-acts-weird-in-high-sierra/ Share on other sites More sharing options...
