My H9 is now not discovered by my Mac at all.
I have toggled the bluetooth on and of of the H9 as per the instructions but the computer does not see it . The blue LED on the H9 is lit.
Well, if I were you, I'd reset my H9s system setting by turning it off and then turning it on again with the right footswitch and the HotKnob button pressed (the button in the upper left hand corner of the H9). I'd restart my Mac, and I'd put my H9 right next to my Mac while sorting this problem out to make sure the distance between the two wasn't causing problems.
