If a certificate is automatically trusted by a client program, that means
that the client program (or the certificate store it references) trusts that
certificate or the certificate's issuer. Some clients (such as Internet
Explorer) ship with a list of "trusted roots" - certification authorities
that we trust to issue certificates to servers. Other clients ship without
trusted roots, and the user will need to install CAs' certificates to ensure
that certificates can be trusted by the client.

Obviously, the CA certificate for the CA that issued your certificate is in
the default set of trusted roots on the Windows systems, but not in the set
of trusted roots on the Macs. You can fix this in a number of ways - either
get the clients to install the CA's certificate, or your certificate, or get
your server's certificate from a CA that is trusted by more clients.
