Yes, this was a bug that was introduced in loscil and has been fixed
in develop branch.  The fix will arrive in 6.10.0, which is planned
for before the Csound conference at the end of the month.  If you can
build Csound on your Mac, that'd get the fix, or elese maybe someone
can offer to put up a build somewhere online.

Never-mind, got it.

I had followed an older link and tapped csound/csound instead of kunstmusik/csound.

All’s well. Works great!
