SecureFX Synchronization not working on Mac?

[BurnettX360]

When I try to synchronise a remote and local directory with the file synchronisation options in SecureFX I get the following error, no matter which folders I select, both local as remote. I'm 100% sure I have write permissions in the selected directories since In RemoteFX filetransfer mode I can create files.

Here's the error:

Create directory failed: Operation not permitted.
