FWIW, I once took a quick look at how audio is implemented in OSX. My understanding was that the native interface only supports callback based audio. My gMFSK, and I believe most other linux soundcard programs use blocking or polling for audio data and thus need non-trivial modifications to be ported to OSX. The changes needed shouldn't be rocket science, but lacking hardware to experiment on, I soon lost interest... /Tomi
