Here's a list of the Mac software I've been using for radio.
I'm a newer Mac user and been looking for good amateur radio software. Here's a list what I've been using, in no particular order.
ChronyControl - for accurate time keeping.
QTH by W8WJB - fully featured APRS software.
SDR-Control for ICOM - pricey, but useful radio control for the 7300 and more, has built in FT8/RTTY/PSK31/CW.
HAMRS - easy to use multi-platform logging program.
Serial 2 by DecisiveTactics- as advertised it will connect you Mac to anything.
AntScope2- works great for connecting your RigExpert Antenna Analyzer.
And finally I can't wait for the new SDRConnect by SDRPlay. It will be a multi-platform software suite for their great SDR's. Currently I'm using CubicSDR which leaves a lot to be desired.
