I am using a Pagasus2 R2+ on a MacBook Air (Retina, 13-inch, 2018) ; on macOS Catalina 10.15.3. and it will not power on. When I press the power button it blinks Orange and does nothing. It will not show up on my computer at all. I am connected via a Thunderbolt 3 to Thunder bolt 2 cord. 

I also have a Macbook Air (Retina, 13-inch, 2017) ; on macOS Mojave 10.14.6 and it connects fine via a Thunderbolt 2 to Thunderbolt 2 cord. It boots up automatically and seemlessly on that laptop. 

I have tried to update my software for Pegasus, but nothing is working.
