Could you share a recording or a (full resolution) screenshot? Like this it's hard to say anything...I have an old MBP15 with Mac OS Sierra on it. Installation went smooth and look like it works fine. I'm using a mic of my Meizu headset right now and it doesn't seem very reliable. I know my watch is within 20 seconds and TG shows from -80 to +50. I guess I need a better microphone right?
