BE16FP2 Installing Veritas Agent for Mac OS X

I'm trying to install BE 16FP2 Remote Agent on Mac OS X 10.11.6  without any success. Old RAMS packages from BackupExec 2010 are no longer working, New RALUS 1142.1632SP from BE16 DVD are failing with "not supported platform error"

I was able to install BE 2010 RALUS and run update to 1142.1632SP (ralus.ver is showing correct 1142.1632 version) but my backups are still failing with the following error

The remote computer is running a previous version of either the Agent for Windows or the Agent for Linux. Due to security enhancements, the existing trust between the Backup Exec server and the remote computer will be lost. You must upgrade the remote agent to maintain the trust and enable the newest features of the current version of Backup Exec. Refer to the link below for more information:
