I have upgraded my Mac OS to Sonoma, now when I launch ESDR2 the program opens but when I press the start button I just get an error saying Can't connect to SunSDR2
First thing I checked was the firewall and it is off which I found strange. On further investigation it is off as default in Mac OS as there is no software with open listening ports by default.
I fixed this by simply going into options/device and clicked discover.
Even though nothing had changed with IP etc the device was discovered and everything working as before.
