I actually had some "...Data.cat" and "...Data.cat.hrs" files created yesterday. I think that indicates that I had connected the app to the Davis Console via the SiLabsUSBDriver64. However, there have been no new Data files created since those first two. I simply dragged the one I had been using in 10.12.x.
It appears that 'drag-n-drop' is not effective to put it kindly (others can consider my actions not so kindly!). The point is, there is a version that came out this January, I'm sure I installed it on the
old mini, but I probably did not do that on the current iMac, since it does not run WC and is not connected to the Davis hardware. So, dragging a rather old copy of the driver only worked long enough to choke WC. My bad... again...
Interesting...
The name/version/loaded of the driver that is on my iMac:
SiLabsUSBDriver64/3.0.0d1/No
The newly installed name/version/loaded on the new mini:
SiLabsUSBDriver/5.0.4/Yes
I had noticed that the 'drag-n-dropped' old driver (3.0.0d1) was also listed as
not loaded. That's was my second clue that something was awry! Two bats against the head is usually enough to at least get my attention, even if it doesn't 'encourage' actions...
