It runs on the mini but through the rPi. Using the rPi as server to Mac kstars client the internal guider works fine. I have a wired Ethernet connection so the lag for guide camera image files is not really a problem. My wording was a little ambiguous kstars and ekos run on the Mac and control everything (including auto guide). The rPi serves up the devices (mount, cameras, etc) to the Mac.
