Can't find android device using “adb devices” command

Question

I am developing Android application on macOS and my application runs well on the emulator. I want to run it on the device, but when I run adb dev

Answer 1

Are you by any chance also using the app EasyTether while connected to your Mac? If you happen to use this app, you're in luck, because the solution is to call:

sudo kextunload -v /System/Library/Extensions/EasyTetherUSBEthernet.kext

from a terminal. I forget if you have to reboot or not.

This will disable tethering, but you can now see your device via adb.

To renable tethering once you're done debugging, use

sudo kextload -v /System/Library/Extensions/EasyTetherUSBEthernet.kext

Of course, if you're not using EasyTether, then hopefully someone else has an idea....
