Reading TFM did, indeed, remind me to switch the handshaking security options (wireless setup on the OM5ii) to "private". This time scanning in the "QR" pattern not only caused my trial version of Cascable Transfer to recognize of the OM5ii, but also to go on and upload thumbnails of the camera's stored images. Clicking on these fairly promptly produced a full-size image, though -minor gripe- you always have to exit full screen and return to the thumbnail catalog to click onto and expand another image, (It would be much handier to be able to move directly form one full screen image to another, as Preview allows one to do.
The ability to select RAW or JPG or both is especially useful, as I usually shoot both, but usually will want to wait to process the ORF's when I get back to my studio/man cave. It also speeds the rather slow upload (from camera to computer) process considerable.
I will buy the program It is handy, and saves wear and tear on that single ISB-C port.
Do wish that it also worked for the Panasonic G85,
