I was using PicoScope 2205 under Windows with my old MacBook pro into a virtual machine of VMware without problems for years. I received a new mac and I reused the same virtual machine. Now PicoScope has a strange behaviour: when I simply measure a continuous potential (+3V), I get 0V on the display, after a discharge. When I ground the probe, I see the discharge again after releasing the grounding and the final displayed value is again 0V.
It looks like the CC/CA button is always switch on CA, so cutting the continuous composant.
I tried to uninstall the SW, use the new beta release: same results. Then, I re-installed 220.127.116.112: same results.
I first thought that the device is damaged, but when I use it with my old mac with 18.104.22.1682 too, it works.
Both MacBooks have the same OS release (Yosemite 10.10.5). On the new mac, VMware fusion 7.1.3 is installed when the old one has 7.1.2.
I also used the OS X version of PicoScope but noticed that each time I used it, I cannot anymore flash a development board with a JTAG. I then need to reboot my machine (occurred on both MacBooks). So I prefer to use the Windows version.
Has someone experienced a similar problem and solved it?
