arduino.app is in /Volumes/Samsung_SSD/Arduino-1.8.5/
the Sketchbook path is changed to /Volumes/Samsung_SSD/arduino-1.8.5/Sketch
I do not find a way that Arduino IDE has the preferences.txt file in
At the start it creates a folder Macintosh HD/Users/kepar/Library/Arduino15 with the preferences.txt file.
To copy this file to /portable and restart doesn't change anything
What do I wrong?
