@btan I am able to install the version shared by yourself. But the problem with Forticlient VPN 6.4.x version with macOS Mojave is that it doesnt save any configuration. Are there any post installation steps that i need to perform post the installation.
Nopes i do not have any other vpn client. Yes the issue is pretty strange. Is there anything specifically you did in the folder access authorizations for this version or any particular write permission that should be given..Maybe that could help me look further down.
@btan I do not have any fmon/fmon2 files in the installation directory.
You may have to manually add fmon2 to the list, as it may not be in the list of applications to allow full disk access to. Click the + icon to add an application. Browse to /Library/Application Support/Fortinet/FortiClient/bin/ and select fmon2.
