Octopus / Toolchain on MacOs

The original dev kit Arduino IDE (TM) + Ardublock + portable libs was package for Windows (TM).
If you want to get all running on your loved MacOS … here you go!

First make sure you got the right CP201x USB/UART driver installed:
<= 10.10 MacOS go with the legacy driver: https://www.silabs.com/community/interface/knowledge-base.entry.html/2017/01/10/legacy_os_softwarea-bgvU
> 10.10 MacOS go with the latest driver: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Next download the Arduino 1.8.5 IDE (or newer) from the https://www.arduino.cc/en/Main/Software
webpage for MacOS. Install the package.

Get the latest dev kit for the Octopus „IoTW.zip“ from https://seafile.rlp.net/f/bb6bdbfe28034cd4861a/ webpage. Unzip it. Within this package you will find the arduino-1.8.5 folder, in which is a folder called „portable“ – copy in the next step into the Arduino.app package.

First you do need to open Arduino.app package while right click on the logo:


following context menu should be visible:


open „package content“ – which give you following structure:


now copy the „portable“ folder into the Java (1) subfolder – almost done.

Start the Aruindo.app (double click)


now you should find unter „Tools“ the Ardublock. Go to „Board Manager“ and re-install the
ESP Community (ESP8266) toolchain. By searching for „ESP“.


(you might need to clean up the old „windows“ bin from the packages directory – manually)

If all went right … have fun!
