I have teensyduino 1.8.7? On my work machine. I decided to try programming an Adafruit Itsy Bitsy M4 with bluefruit thing. And had no end of issues. I swear it was switching processors on me while it was compiling. I had to re-choose the processor twice, three times? I was never able to get it to finish downloading "blink". Then it just completely crashed my Mac. Black screen, reboot.. So I figured I'd come ask. Do you guys know any reason that this was the wrong thing to try?

I gotta' go ask Adafruit the same thing as well.
