Forticlient 6.2 Giving me the error "104" on Mac with Mac OS Mojave

When attempting to connect to my firewall using VPN, I'm running into an error that says "

Connection was terminated unexpectedly." When I looked online for the solution, there is supposed to be a section in my security preferences where I should be able to click on a button that says " ...developer "Forticlient, Inc" was blocked from loading". However, that is not the case with me. As you can see on the screenshot below, that option is not coming up. Have anyone else run into this problem? Are there any other suggestions? Thanks.

Where did you find this version?

I just tried and am getting the same error -104....




I finally have this working.  :)


Per Fortinet:  the only version of the Forticlient that is working with Mojave is:

I have this issue as well.  It complained about a blocked system extension and says it is not compatible with this version
