You typically need two interface circuits.

One is typically called a sound card interface circuit, which connects the mic and headphones circuits together--often with transformers.

The other is a serial to USB interface. It is much harder to write USB port software, so most ham programs use serial ports and assume that the user will buy an inexpensive serial to USB interface.

Not exactly sure what you mean by running digital on an FM rig. Perhaps you mean Packet Radio?
The developer of a soundcard packet modem says he doesn't have a Mac, but would support a MAC developer in porting over his software.

FLdigi will run on OSX, but the modes it runs typically aren't used on FM rigs--it is normally used with HF SSB rigs.

In the past, we have posted news stories about scams and bogus emails, but these days, you can find warnings about scams on broadcast television.

As you point out, people are only interested in warnings if they don't know about them already.
