I was looking for an alternative client for macOS because I hate the windows style of ciscoVPN client for mac,

And I found this. http://www.nexumoja.org/projects/Shimo/

Shimo is the best choice for mac for the following reasons;

• More stable and well integrated than cisco vpn client
• Nice statistics screen
• Keychain integration
• Connect on login
• Can be easily integrate with growl for notifications
• If you’ve installed cisco VPN before it will import your previous settings.

I think that you all will enjoy it
