If want to keep your system clean, you can also use Genymotion without Android Studio:

1. Find Genymotion's copy of adb. On macOS this is normally /Applications/Genymotion.app/Contents/MacOS/tools/.
2. Add the Genymotion tools directory to your path - execute/add the line export PATH=/Applications/Genymotion.app/Contents/MacOS/tools/:$PATH to your ~/.bash_profile or ~/.bash_rc.
3. Make sure that you can run adb from your terminal.
