Hi, installing twice for me did the work... "Do note that you might have to install it twice for it to work, as the first install will just remove the existing driver. If it's installed, there should be a "SiLabsUSBDriver.kext" file in /Library/Extensions with a date created of June 16, 2017.". It's not wotking for you? I'm on macOS High Sierra 10.13.6
for others with this issue, I solved it on OSX thanks to this page:
As discussed in the following thread, it appears the v5.x SiLabs driver is completely broken.
Fortunately the v4.x driver, which is included in the "Legacy MacVCP Driver" folder in the same download, works fine. Do note that you might have to install it twice for it to work, as the first install will just remove the existing driver. If it's installed, there should be a "SiLabsUSBDriver.kext" file in /Library/Extensions with a date created of June 16, 2017.
Every time I try to connect, kstars crash with my previous reported log, so I'm unable to use the sesto senso 2 focuser with kstars. Anyone else with this issue?
on osx high sierra 10.13.6, kstars crashes when trying to connect to senso 2:

For any others have this isuse, I can connect to the sesto senso 2 after install this driver, on osx 10.14.6:
Hi all! just received the sesto senso 2, but is not connecting on kstars 3.4.3 on an osX computer.

The camera is well attached to the guide scope, and the guide scope is well attached to the main scope, there's no movement, it's like a single block. Anyway, repeating from one day to another the same PA routine gives me exactly the same values for main and guide scope (+-2' / +-9'), if it was flexure the value for guide scope the PA error would never be the same?
focal length: 1280 mm
camera: canon EOS 4000D

one doubt: on the main scope I'm not taking pictures at full resolution, I'm taking pictures at 2592x1728. These are the values that I've write in the indi control panel, both for "Image settings" and "image info":
I've been using kstars and ekos during lasts months, and I'm in love with it. I'm always do the polar alignment routine with the main optical tube (c8 with 6.3 focal reducer), but last night I tried with the guidescope , and there's significative differences... With the main scope ekos gives me a polar error of 2' 13"
