Hello - this isn't so much a question as it is an FYI.
If you're using a Teensy on a Mac (or any arduino really) you'll notice that there are no serial ports detected in Arduino 1.6.7 (or 1.6.5). You can't open the serial monitor (except on the worth-little bluetooth serial), and the Audio/FFT example won't run. Also it appears that the Teensyduino loader won't be able to reboot the Teensy automatically (requiring a buttonpress each time).
The fix is to disable "SIP", in the Recovery console. Details here - http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/
After that, you are back to just your own personal failings stopping you from Teensying.
