Installing the latest version of teensyduino 1.51 works well on OSX 10.13.6
Everythings works as intended.
However, after rebooting the mac, Arduino IDE will fail (crash)
Only fresh rei-nstalling Arduino IDE and Teensyduino will solve the problem.
To only reappear on the next reboot.

Anyone any hints as how to solve this?
Thanks!
Floris
