This is a Macbook Pro running macOS High Sierra (10.13.6). Arduino IDE is 1.8.12.
Before installing Teensyduino, the Arduino IDE worked fine with my Arduino Mega 2560.
I then installed Teensyduino 1.51 via the link labeled "Macintosh OS-X Installer (10.7 - 10.14)". I told it to use /Applications/Arduino.app -- Succeeded.
My brand new Teensy 4.0 is connected via USB, its orange LED blinks, and stops when I push the button.
When I run the Arduino IDE, I get "Arduino quit unexpectedly". Happens multiple times, every time.
Suggestions?
(No source code to post -- didn't get that far.)
