Citrix SHA2 Certificate error on Mac Receiver - You have not chosen to trust "RapidSSL SHA256 CA-G3" Error

After a recent renewal of our Citrix FQDN Certificate all users connecting via Mac are receiving the following error when launching an application.

You have not chosen to trust "RapidSSL SHA256 CA-G3" Error the issuer of the servers security certificate.

We have over a 100 in the field so updating the clients individually is a last resort.

We have tested the latest receiver with no luck.

Any advice would be greatly appreciated.

I would suggest to check the certificate and see it is valid www.sslshopper.com/ssl-checker.html (just give the external access of you citrix access). I am sure that this will give some clue where the issue actually lying.

The only way we have been able to resolve the issue is to provide the root certificate for Rapid SSL for the individual MAC users as it is not provided in the keychain and there appears to be no way to automate the download from the citrix client or Web Interface,
Even with Yosemite the root certificates for Go Daddy and Rapid SSL are not included and have to be added manually.
