Thanks for that! I understand that it is an old driver for him, but it is not for me I'd appreciate support for it and packages supporting newer versions of Linux and macOS.
No need to apologize Rob. I hadn’t used the Shoestring motor focuser for a long time but mounted it on my new telescope today and gave it a try. I couldn’t get the Mac version to work but I was impatient so that’s probably why. The deb amd64 version still works as I fund out tonight so for now I am a happy camper
