You are unable to connect to the DeskPack, Automation Engine, or File Server by host name on the Mac OS X.
To rule out Esko software problem, first try to ping the server you wish to connect to using the Terminal application. If this action is unsuccessful, it generally means that the DNS settings are incorrect and you should contact your internal IT department to resolve the issue.
As a quick fix, you can edit the Host Table.
This is highly not advisable if you are using dynamic IP addresses.
You must know the root password for the Mac system, IP address of the DeskPack or Automation Engine Server, and the name of the DeskPack or Automation Engine Server.
Open Terminal.app via Applications > Utilities.
Type the following command at the prompt: sudo nano /private/etc/hosts
Enter the root or administrative password and press ENTER. No characters will show when typing the password.
Use the arrow keys to navigate to the bottom of the hosts file to make your modifications.
Add the server IP address to the bottom of the list.
Press the TAB key.
Enter the (host) name of the corresponding server.
When finished, press CTRL+O followed by ENTER/RETURN to save changes.
Press CTRL+X to exit out of nano.
Quit Terminal when finished.
Your Mac system should now connect to the server(s) by name.
An example Host Table will appear as shown below:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
