i tried the Terminal commands at (Fixing Auto Sleep) of the post but don't help.
This plug comes with 2 thick wires.If you haven't already, check the actual USB3.0 connector attached to the motherboard. On more than one occasion I've seen the cable come loose from one of the ends, causing one of the ports to not work properly. Make sure the connector is firmly seated with all pins making contact. Sometimes I've seen the connector get pulled by the cable routing or the heavy wires of the connectors putting strain on the port itself.
Also, is this plug connected to 2 thick wires? Or one? (most cases usually have 1 wire per USB3 port)
Is the Radeon VII installed in one of the internal PCIe slots or in an eGPU chassis? Quite a few people here are using the Radeon VII successfully (internal PCIe slot) with and without iGPU.Has anyone gotten Radeon VII to work under 10.14.6 with IGPU enabled on this board? Trying to use do this as iMac 19,1.
I have successfully gotten it to work in Slot-1 and in the eGPU, but only when the iGPU is disabled.
- When you say it doesn't work with IGPU enabled, what error message or abnormal behavior do you see?
- Are you using AptioMemoryFix.efi or OsxAptioFix2Drv-free2000.efi?
