Just got a new iMac Pro running Mac OS High Sierra. Teensy loader seems to work only once. The second time I upload code the Arduino IDE often complains that "the compiler quit with no error message". Quitting Teensy loader and recompiling fixes this problem (well, at least for one iteration).
Doesn't *always* happen, but once the problem starts up it's relatively consistent.
