Updating FortiClient 5.6.0.703 in OSX 10.14

[AdamSeddon]

Hi new to forum looking for any help with trying to update the forticlient from ver 5.6.703 to 6.0.1 on a iMac running OSX 10.14 I am getting warning messages about fcundate not being compatible (32 bit) so I have tried updating the client when i download l and install I get a message saying no forticlient installer found on fds and the installation just hangs there. Older client version 5.6.703 still running in background and still able to connect to work resources remotely just wanting to get rid of the irritating update message.

any help ideas greatly received.
