Hello all, I recently purchased the midi controller Vestax Spin to start DJing a bit on my MacBook Pro but when plugging it into my usb, it wasn't recognized or anything. I know it's on because of the light on the Spin. Wanted to know if there's anything I can do? P.S. Sometimes when I do plug in the Vestax Spin I get this error on the screen telling me to power down or restart the computer. Any help on this matter would be great.
