GroupWise intall on Mac OS 10.8.5

Anyone have advice what to troubleshoot on a GroupWise 8 client install on Mac Book Pro using OS 10.8.5. The client installs but the issue is with startup. The GW client asks for un/pw and when it is provided the application just hangs there. We end up using "Force Quit" to get the GW 8 logo off of the screen. I have GW 8 running on my MBP that uses 10.9. Honestly, I wish that Novell would have a Mac client for GW14 since they have ZCM managing Macs.

Anyhow, thanks in advance for any support.
