According to the RR Wiki the suppoorted software is
ARC250
Control Freq v2
ID Tracker (just for ID tracking not programming if I recall)
ProScan
Scancat Gold
Scan Control
ScanPro250
Spectrum Commander
Trunkstar Pro
Trunkstar XLT
Not sure if any are MAC compatible but take a look.
Most people will probably just suggest a Windows type emulator on your MAC.
