[Csnd] runtime failure MacOS

Dear list,

for me that issue is still not solved - probably because I do not exactly know how to do it. Maybe someone can give me a more detailed explanation on what to do.

First I would like to make sure, if the issue Dave reported is related/ the same as this one:

I am on Mac OSX 12.6 and my version of Csound is Csound 6.17.

The output on console is this when I try to render can be found below.
Also blue crashes when I try to render, no matter if realtime or deferred time.
Csound 6.16 runs fine, 6.17 causes these problems.

What exactly do I have to do?

As a test, you might be able to grab the libsndfile.1.dylib from 6.16,
uninstall, then install 6.17 and copy that libsndfile.1.dylib in. I
think that would work.

(BTW: It should be clarified this is 10.12.6)

Potentially you could simply copy the whole libs directory from 6.16 and replace the one in 6.17 with it.

Unfortunately I don't have the means to produce binaries that support older MacOS versions at this moment.
