As of now there was no VPN Client 5.x available for MAC OS.
The latest and last available client is vpnclient-darwin-4.9.01.0280-universal-k9.dmg
Cisco has developed the AnyConnect Secure Mobility Client as a “next generation” Virtual Private Network (VPN) client
Most recent client available is anyconnect-macosx-i386-4.0.00061-k9.pkg
Hope it helps you somehow.
This is very frustrating and waste of time ,,Cisco direct me to download page with my name and information then when I wanted to download Anyconnect for MAC or Windows , it keep sending me to profile page , I KEEP updating and Nothing happen ,, this is so much waste of time to set VPN via Cisco's none sense
