Unable to install N360 multi device on Mac

When trying to install N360 on a mac on 10.9.4, it fails after running the downloader/installer. Fails silently but I found the following entry in Console:

 

Application App:"Norton Management Installer" asn:0x0-29029 pid:706 refs=7 @ 0x7fc65062bf80 tried to be brought forward, but isn't in fPermittedFrontApps ( ( "LSApplication:0x0-0x2b02b pid=746 "SecurityAgent"")), so denying. : LASSession.cp #1481 SetFrontApplication() q=LSSession 100005/0x186a5 queue.

 

Please advice.
