I bought an Arduino UNO (I believe it is not the original), I downloaded the IDE, I installed normal, I connected the board (it was turned on normally, I went into the IDE on tools> cards and I selected Arduino / Genuine UNO, I went into Tools > ports was to select usb, but does not have this option, only bluetooth ... What can I do to be able to recognize and be able to program? Remembering that I'm with macbook pro, and mac os x latest version ... Thank you
