FALLOFMAN Posted December 26, 2016 Share Posted December 26, 2016 System: osx sierra on its own HD motherboard: asus p8z 77v -lx cpu: intel i5 3570k ram: 8 gig corsair vengeance gpu: evga gtx 1080 6gb vram single fan I was running el capitan which had all usb ports working fine. Now that I have updated to sierra, the two front usb ports which I use for mouse and keyboard are working perfectly, however, I have 6 more in the back which don't work, two of them work from time to time but now my audio has stopped working even though the audio interface is plugged in, just not showing up in system preferences/sounds Anyway I can get all usb ports running?
