Q: Does the Old Bird software support Macs?
A: All Old Bird's avian flight call detection software was originally developed in 1998 using MatLab (and it's Simulink & Real Time Workshop toolboxes). This was around a low point for Apple's commercial success and MatLab's developer, MathWorks, had stopped supporting the Mac OS -- this is why the Old Bird software only works on PCs. Since then MathWorks began supporting the Mac OS again and we looked into getting a MatLab Mac license and porting the old PC MatLab code to Mac. But the cost of the license, including key toolboxes) had risen to over $50k.
Old Bird software can be used on a Mac running in PC emulation mode. This was verified in 2012 using the PC emulation software Parallels (~$80 USD).
