I faced an issue with my Nexus 5x which I just acquired for Android 8 development: even after setting the development mode to be on, USB debugging to be on, Android Studio or adb refused to see it. (On the other hand, my Nexus 6 works fine...) Tried a few USB-C wires (including one that said compatible with Nexus 5x). and the result is the same.
I am using a Mac.
1) Is this a hardware defect or is it a USB mode I need to set? 2) If it is not possible to connect, how do I do wireless development (without connecting via wire first)?
