The latest OSX version available to download is 3.4.3
You can also compile it from github.com/rlancaste/kstars-on-osx-crafts

I do not think 3.5.0 is considered stable.

I have been testing this home position a lot now, and it is extremely reliable. I'm still waiting for my USB cable to connect this mount to my laptop.
Hopefully the park position of Indi is as good as the home position of the hand controller.

Also looking at options to add limit switches to avoid crashing the mount.

I am really surprised that there is no mechanical switches build in this mount to avoid collisions.

I do not think that my counterweight bar is 100% square to the top of the DEC motor box. I can clearly see it's offset by a small amount.

The latest official firmwares are

Go2Nova 8408 hand controller firmware (V190422) (Released 1/31/2020)
CEM25 R.A. motor control board (V190422)

I am way behind yours, Stephane!

I don't think firmware is the problem.
