Slice Posted June 20, 2017 Share Posted June 20, 2017 I am sorry I forgot who is the author of the idea of this patch for Sierra. In High Sierra the kext binary changed and new patch required. Initial state as you see there are only 15 ports. 14 HS** and one SS01. The reason is AppleXHCIPCI.kext has a restriction in 15 ports and count both USB2+USB3. Intel chipset Z170 has 14 ports USB2 and 10 ports USB3 but we have 14+1. Kernel log tell us kernel: (AppleUSBXHCIPCI) 000001.769617 XHC@14000000: AppleUSBXHCIPCI::createPorts: ports limit reached. Not creating the remaining 11 ports The patch for Sierra found: 83BD74FF FFFF10 replace: 83BD74FF FFFF19 For High Sierra found: 837D8410 replace: 837D8419 Or visual The result 11 Link to comment Share on other sites More sharing options...
