Well, I had the issue of KStars not detecting the microtouch focuser under Mac, while it worked fine under Linux. Here’s how I solved it.

First of all, the key was to download the USBtoUART Bridge VCP drivers from Silicon labs for MacOS:

CP210x VCP Mac OSX Driver from  www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

Once installed, KStars 3.5.6 (under Mac Monterrey) detected the Microtouch focuser in Ekos. Hopefully it will be useful for other users.
