I flashed my first device with MicroPython today. I used a Wemos D1 Mini (ESP8266) and flashing worked as supposed. I used macOS 10.13 to flash and also verified the correct installation using esptool.py. I've also been using Arduino on this machine for months without any problems. But as soon as I try to access REPL through a terminal program - no matter if the macOS-native screen or picocom, I just get no response at all from the ESP.
The output just stays empty on screen (screen /dev/cu.Repleo-CH341-001314FD 115200) and picocom (picocom /dev/cu.Repleo-CH341-001314FD -b115200) just says "Terminal ready".
It works fine with PuTTY on windows so I can only assume that the installation of MicroPython on the ESP worked correct but I would prefer using my Mac as all my dev-tools are on macOS.
Thank you for the replies so far - and sorry it took me so long to react but I wasn't at home for a few days...
> Try to reset the module, while connected to the UART. I have same issue and I'm using Mac. I'm also using Esplorer (java based) as it has a proper interface and Micropython reference as well, unlike 'screen'.
Tried that several times unfortunately without any change... and I also tried different programs to access it.

Also no difference
What I did notice: It works on my MacBook which runs macOS Mojave - my main workstation still runs on High Sierra as it can't run a newer version. I am even more confused now...
That might be a workaround though my whole development environment is on macOS... And I could just use the windows machine then as well
I am planning to replace this old iMac anyway at some point as it doesn't get updates anymore. So I will probably just use my Macbook till then.
