As a Mac user I’ve had a hard time with drivers.
The latest issue is that I can’t connect my Baader Steeldrive II to Ekos.
It seems that I‘m the only person using INDI on Mac with Baader, so I don’t think that problem will be solved soonish.
Now I‘m thinking about going the easy way buying a laptop and use ASCOM.
Or buy a Raspberry 4 and Stellarmate still using my MacBook Pro to connect and control my hardware.
Currently I have connected my 10Micron 1000 to ethernet and my focuser and ASI to USB.
My MacBook is connected to my WiFi.
Question: If I connect camera and focuser to the Raspberry with Stellarmate and the Raspberry to Ethernet and use my Mac to control everything. Will my (Mac only) problems solved?
Short answer: yes.
I am coming from the other direction, having used a local headless computer (Fitlet, lets say a RPi on steroids) with all connections and connecting from a Mac. With the new M1 Macs I had hoped that a Mac mini at the scope would make a great user experience. But I am running into similar connectivity issues as you describe, also with a focuser (Esatto).
Using RPi as server where the devices connect to and connecting remote from your Macbook running KStars/Ekos is a great setup. And driver/connectivity issues will always pop up from time to time, but generally it has been a smooth ride. Only thing is if your camera sensors becomes bigger, and larger files need to be sent over, transfer speed may become prohibitive. You seem to have a lot of hardwired ethernet connections, so should be good. I've found an ASI1600 to work perfectly, but my ASI6200 takes too long to transfer the files. So I run everything KStars/Ekos on the Fitlet and use VNC viewer on the Mac to control.
I run my setup with a locally mounted Raspberry Pi 4 (Astroberry from SSD) and talk to it from the house via Ethernet with my MacBook. The issues I had with WiFi reliability went away with the wired connection. I did have to add a 12V powered USB 3 hub to ensure proper voltage levels for the bus powered USB devices. The Pi is powered by an up-rated 5V supply to prevent under voltage events.
The issues now are typically weather related than computer related - a nice change.
