We recently upgrade to OS X Yosemite and now PicoScope 6 won't work. It starts, it detects the device, but it just reads 0 V (exactly) from all channels, all the time.
I connected it to a PC and could confirm that the hardware works as intended. The green light also flashes, and it makes its funny noises when PicoScope 6 starts up.
The software is in capture mode and if I add a measurement (like DC Average) Capture Count increases, but it always reads 0. I attached an image for extra clarity.
