I think the 6.17 build is not compatible with older versions of OSX, you will need to get an earlier version for that.
However the build we’ll release for 6.18 is compatible all the way down to 10.9.

yes, it’s an annoyance the issue of non-backward compatibility. Since Csound has a number of dependencies, I had to ensure they were all built with backwards compatibility, but I think this is OK now all the way to Yosemite. 

Note that the Python opcodes are now provided as a separate install, but at the moment have been built for x86_64 only and so they will not run in native M1 mode. Also the question of backwards compatibility is not clear to me in regard to these. Once we have this release out, we can see what issues are outstanding.

As usual, the difficulty we have is that while there are many demands for versions and different hardware etc, our development team continues to be very small.
