Well, I moved, and after some extended storage my old puck started melting (that strange plastic rot that happens sometimes). So I got a new Calibrite SL, but it isn't recognized by SpectraView II no matter what. I will try and call NEC, but wonder if anyone has had this.
Mac M1, NEC PA272W, Calibrite SL connected to USB-C and to monitor's USB in-port.
thanks in advance,
