so, here we are two years later, and there STILL isn't any G4FON for mac available. this is probably due to a large extent that the developer, ray burlingame-goff, passed away in july 2021. i have continued to look for a G4FON source for mac, but may have to buckle and get a cheapo laptop. i REALLY want to use long island cw club for my CW training, and they highly recommend the G4FON software. so, there's that.
