Hello.
I was told that Rob could help with this, not so new topic.
When I looked at the OS requirements, to install newer versions of kstars, versions 3.4.0 and newer only required OSX 10.12+
Unfortunately, when I tried to install and run version 3.4.0, I got the error that said my OS was to old to run it.
I am running version 3.3.9 with no issues. I suppose that the downloads page should be edited to reflect the minimum OS version needed as 10.13 (or higher?).
