So that *is* good news ! If you could share more details, that might help others as well.

Have you seen the C source code of the Mac SSL Plugin ? It is written against an API from Mac OS System 7, from before Mac OS X, that is an OS from last century, ~199X. This is ancient, you won't find many developers who want to work on that, nor does it make sense towards the future.
OpenSSL is also available standard on Mac OS X, the Linux plugin could just as well be used there (give or take).

The SSL plugin code only looks for the certificate and the key but not for the CA. So under linux it finds it in the system but on Mac OS I couldn't do the same. I imported the CA in the keychain but openssl does not seem to find it there.
It is very simple why it does not work on Mac (like I said), it is just not implemented !
Try finding where certName is used in sqMacSSL.c, there is a setter and getter, but it is simply not used, so it can never work.
In sqUnixOpenSSL.c on the other hand, there is
/* if a cert is provided, use it */
if(ssl->loglevel) printf("sqSetupSSL: Using cert file %s\n", ssl->certName);
if(SSL_CTX_use_certificate_file(ssl->ctx, ssl->certName, SSL_FILETYPE_PEM)<=0)
if(SSL_CTX_use_PrivateKey_file(ssl->ctx, ssl->certName, SSL_FILETYPE_PEM)<=0)
