On the mac I installed the Citrix client, but on connecting to the server I got the following error
SSL Error 0: YOu have not chosen to trust "/C=US/ST=
I logged into my Linux box and copied over the following certificates
EquifaxSecureeBusinessCA-1.crt
EquifaxSecureGlobaleBusinessCA-1.crt
BuiltinObjectTokenEquifaxSecureeBusinessCA2.crt
BuiltinObjectTokenEquifaxSecureCA.crt
from the following Linux folder
/usr/lib/ICAClient/keystore/cacerts/
to the following mac folder
/Applications/Citrix ICA Client/keystore/cacerts
Actually I just one certificate, and I can get it from here
