I've tried several different ways to try and connect a new Trinket 5V to my Mac to start working on a new project. However, I'm not able to even connect to it. I've tried switching cables, USB ports, even tried choosing several different Board versions (8MHz to 16MHz) but still nothing. I keep getting that same error. Help, please!
