Hi all!

I am migrating all my stuff to a new macbook, which have the latest OS, however as I downloaded the new Teensyduino which now is a package which includes the application, while I try to change from one window to the other, or change the Board for my sketch, the application just crashes and crashes.

As the title states, these are my versions:

Teensyduino (Arduino 1.8.11) in MacOS Catalina 10.15.2

Anyone having this experience or the admins have a suggestion or workaround?
