Latest K3 utility doesn't play well with Catalina


Evening all from the UK
Tried to upgrade my K3 with the latest firmware using my MAC and the new 64bit utility.
K3 'froze' at LD.
Any number of power off and re-starts didn't work.

Fortunately I had a Win 10 desktop with a direct Rs232 port.

I eventually managed to get firmware to load using the Win 10 machine.
I shan't be using the MAC utility any time soon!
