It looks like there's a new (fairly limited feature set) version of Touchstone Pro available on MacOS now. Despite finding a connection bug in the first few minutes of using it, it seems to at least work in the most basic sense on M1 laptops (running monterey 12.6.4).
However, despite having the wideband license on my 6G+ the app seems limited to 300mhz sweeps. Anyone figure out a way around this? Am i missing something? Tried both "auto" and "high" resolutions.
