High, StevieDvd, sorry it too so long to reply.
I've had zero success trying to get my Mac (High Sierra or Big Sur) to control the EQ6-R Pro mount. I can't get my iPad to talk to it either. I've tried both the RJ45 and the USB on the mount but I've not been able to communicate with that mount either way yet.
The ONLY success I've had so far is with an iphone through a SW WiFi Adapter. I'm currently only using the mount for direct viewing and no photography, no autoguide, etc. The mount also works fine with the hand controller, so that -- plus the fact that the SW WiFi adapter works with my iphone -- makes me think the RJ45 on the mount is fine.
But I my iPad can't talk to the mount through that same wifi adapter, and I can't get my Mac to see that mount yet. On the Mac I've tried Stellarium, AstroTelescope, and AstroPLanner and NONE of them see the mount. I'm thinking there must be some combination of preferences/parameters on the software, the Mac, and the mount (ie, set PC Direct first?) but I can't figure out any combination that works.
Any guidance you can give me for getting my ipad or Mac to talk to that mount on any connector with any cable would be GREATLY appreciated.
