Arduino.h: No such file or directory on Mac

General Discussion
#1

Hi,
Really appreciate it if you can help me on this issue. I am new to Arduino. I just got my M2 board a couple of days ago and followed the guide
http://docs.macchina.cc/m2/getting-started/arduino.html
However, I cannot get my example Blink running, it kept reporting
"sketch/Blink.ino.cpp:1:21: fatal error: Arduino.h: No such file or directory
** #include <Arduino.h>**
** ^**
compilation terminated.
exit status 1
Error compiling for board Macchina M2."

My environment:
Mac OS: High Sierra, version 10.13.3
Arduino IDE 1.8.4
Board:“Macchina M2"
Port:”/dev/cu.usbmodem14111"

Thanks!

Hello! It should be in the Arduino.app package. When you open it in Finder there should be more files visible.

From terminal it should be in:
/bin/arduino-1.8.5/hardware/arduino/avr/cores/arduino

Or you can pull it from GitHub and direct it to a folder on your Mac
