    I can upload and run a sketch no problem, though I do have to press the button every time when the board isn’t set to HID mode. Also, I have no serial communication even when set to Serial.

    Oops sorry macOS! I only see "[no device] (Teensy 3.6) Serial" in the port list. This is after I programmed the Teensy with “Serial” as the USB type.

    Hello,
