I am guessing all the new security stuff Apple has introduced has stopped something from working.

Kanaka 3.0.1 running on server and the client that goes with it running on the Mac

If I set up a Mac with 10.13.1 the plugin will launch and the drives for the user account mount and show up on the desktop.

10.13.3 Plugin fails to launch, but the drives Mount and are accessible.

10.13.4 and 10.13.5 the plugin fails, and the drives fail to mount.

The globe icon is there for the account and when clicked brings up the connection box and asks for the users password. Which will then mount the drive on the desktop.

Any help would be greatly appreciated. I have a large number of new Macs due in this summer and they will be using 10.13.4 as a minimum.

The mounted drives are SMB, but I have also tried an AFP one, makes no difference they both fail.

I tried turning off packet signing on the Mac to see if that made a difference, but it didn't.
