Configuring FortiClient on macOS 14+
Initial Installation
To get started, download 'FortiClient 7.4 VPN-Only' from FortiClient.com - https://links.fortinet.com/forticlient/mac/vpnagent - this should download the latest version - you need 7.4.3 as a minimum.
Once downloaded, double click on 'FortiClientVPN_OnlineInstaller.dmg' to open the installer container and run the ForticlientUpdate.app within. This will download the required components and when finished, click the Launch button to begin the next phase of the installation. This download step can take some time and even fails from time to time.
When/if prompted Allow the FortiTray VPN Configuration addition.

Configuration
The configuration of the VPN service is provided by a configuration file on our registration server:

cd ~/Downloads
sudo "/Library/Application Support/Fortinet/FortiClient/bin/fcconfig" -m vpn -f ./fcconf-user.xml -o import
Select FMRIBUser from the VPN list and use your SSO account when prompted in a web browser window.
