I installed the GM candidate of Mac OS X 10.11 El Capitan and my FortiClient VPN has stopped working. It completes the login, but after connection, no data is transferred - the incoming and outgoing freeze. It is a split tunnel connection and neither network or internet traffic works.
I tried disabling the firewall and System Integrity Protection, but neither had any effect.

I've been trying since the first public beta, and now on the final GM Candidate. The VPN problem is there. Basically, what is wrong is that OS X's resolver is sending traffic out through the primary (original) network interface, even though the route table correctly shows that the VPN tunnel (ppp0) should be used.
When you use a command like nslookup, the DNS traffic goes through the VPN tunnel (ppp0) properly.
DNS name resolution fails because my VPN client is told to use my corporate DNS server, but my corporate DNS server refuses to serve name queries from outside the corporate network. When the FortiClient VPN is connected, OS X's name resolution traffic arrives at the DNS server with the client's public Internet IP address, and hence is refused by my DNS server.
Technically, this looks like an OS X bug. Or, perhaps there really is something wrong that FortiClient is dong. Either way, I hope FortiNet can rectify or take it up with Apple to fix El Capitan.
Facing the same issue. Latest FortiClient(5.3*) did not fix it.
But, FortiClient 4.0.2082 did not have any such issues(though it occasionally stops tunneling on its own).
Waiting for a fix like everyone, but 4.0.2082 is letting me work for time being.
I've gotten it to "work" by getting the DNS to use ppp0 and some route magic. Explanation is on: http://serverfault.com/questions/728702/how-to-get-forticlient-working-in-osx-el-capitan/728707#7287...
Let's hope either party fixes this, because running scripts after establishing VPN is quite cumbersome.
There is a new private build here:

Would you guys give it a try?

Just ran El Capitan updates and it still does not work - bummer

5.4.1 release may be available at the end of February.
P.S. b493 from previous post is different from the official 5.4.0 b493. Developer made the change after 5.4.0 was released.
Try this. A more recent build.
After update to MacOS Sierra the client 5.4.1 works as expected....

In this case no 3rd party software is involved. It is pure Mac. Looks like the problem needs to fixed in El Capitan and not in the FortiClient.
For me, FortiClient 4.0.2082 works without major issues in El Capitan. I think this issue might be the result of some major networking changes in El Capitan.

Do you know of a place to download it from?

Thanks for the link. Unfortunately that version doesn't support FortiToken, so it won't help me.

Second week of Oct doesn't sound bad, provided they have a fix for this issue.
Hi..
I tried to use forticlient on: MAC v10.9, v10.10 and v10.11. All of them install the client, I can connect in a VPN using IPSEC but the traffic doesn´t pass from MAC to VPN. I´ve a opened ticket with Fortinet and Engineer doesn´t solve this.
Does anyone see this problem?
There seems to be issue with 10.11 resolver. When it sends DNS request through tunnel, it uses the IP from physical interface, instead of the tunnel interface.
We opened a ticket with Apple and we are waiting for their response.
To me... I can´t ping any IP Address. And If I use this same connection on Windows all work fine..

That means that the upcoming Forticlient release will not have a fix for the DNS issue on 10.11, does it not?

Seeing how you encounter issues on OS X 10.9-10.11, I do not see how your problem relates to the rest of the thread.
Possibly open another thread and provide details, incl. a proper problem description, config details etc.
