IDE Hard Crashing OSX

Is anyone else experiencing frequent total hard crashes of your MacBook Pro while using Arduino IDE? Happens when I hit the Upload button. Cursor freezes and a few second later a total hard crash. Happens for me when using MKR1000 and USB is direct to MacBook Pro or via a USB hub.

MacBook Pro (Retina, 15-inch, Mid 2015) OSX El Capitan 10.11.5 and Arduino IDE 1.6.9

While there is plenty of evidence supporting a known issue with USB and this version of OSX from a variety of users user a variety of Arduino boards; was curious if anyone is seeing this issue of the hard crash.

I’m having the same issue. Filed a bug with Arduino: OSX crashes occasionally when uploading to MKR1000 · Issue #5212 · arduino/Arduino · GitHub.
