I has a new iMac running 10.12.3. I installed the latest driver (USA-19HS Driver (Mac OS X 10.9 to 10.11) and now when I plug in the Keyspan USB, it crashes my computer with a kernel panic. I think I read that although this driver is meant for 10.11, it is also good for 10.12.3, well apparently not of my computer. Does anyone have a fix for this?
