Can someone please help me out. I got a new macbook pro a few month back and am now trying for the first time to build a new project. I have two cc3d boards that have both worked on previous builds that I set up on my old windows machine. I can not get them to be recognized anywhere, I first put openpilot gcs on my mac and was unable to get the boards to be recognized. In the bottom right hand corner next to the connect button in the dropdown box I cant even see the board there as something to choose. What am I missing? I then tried to get the boards to connect to the older version of gcs on my old windows laptop, nothing there either. Last week I then discovered LibrePilot and how it is now replacing openpilot gcs. So I downloaded the version of librepilot for my mac hoping that the new software would solve the problem, but still the same results. Cannot connect, and can not see what board even being recognized as an option. When I plug in the board both the green and blue light illuminate for about 5 seconds, then the green stays solid and the blue begins flashing on and off slowly. I feel like there is something that I am missing to be able to see the board as an option on the dropdown menu to choose to connect to. Please anyone that could help me out would be so much appreciated. I cannot for the life of me figure out what I am doing wrong and am almost ready to give up...But I wont. I just need your help please.
