i go through the installation description but i can't synch both my own Zoho Calender AND the Zoho CRM entries with my Mac Kalender. 

I set up the synch between Zoho CRM and Zoho Calendar. This is no problem. But when i go to settings and Synch iCalDav i can only choose my own calender from Zoho Calendar. So how can i synch both? 

thanks!
