Hi Kurt,

I can imagine it feels like that and I'm in no way the expert in these matters. I have not done guiding like you are trying. I did see KStars perform a bit faster on the Mac in the case of the histogram calculations of the image viewer. It certainly is a nice port/build on macOS.
No need to edit the files. No need to do anything with the db file.
Do turn on debugging for the camera as you can do shown in the attached.

Let me know if you like me to record a little screencast demo of working with the Sony A7S.

Cheers,
Jurgen
