SyncTerm and MacOS?

Got a guy over on DarkForce! that seems to be having a lot of trouble trying to download any files.

If possible can someone try SyncTerm with the MacOS and see what their results are? I don't have a Mac so I'm at a dead end here. This would be at either 38400 or 19200.

I download with SyncTerm with either Kubuntu Linux (laptop) or my Windows 10 box and downloads work absolutely fine with no errors.

Here's a screenshot of what he says happens every time he tries:

Thanks everyone...
