macOS - SITL - Fails to Start When a Serial Port is Selected

[RobertoD91]

Current Behavior

If I start SITL on macOS with --serialport it hangs:

temp$ rm eeprom.bin 
temp$ /Applications/INAV\ Configurator.app/Contents/Resources/app/resources/sitl/macos/inav_SITL --serialuart=3 --serialport=/dev/tty.usbmodem2051359037561 --fcproxy
INAV 8.0.1 SITL (171d00bb)
[SYSTEM] Init...
[SIM] No interface specified. Configurator only.

If I disconnect the serial port, it proceeds...

Same issue with INAV 9.0.0 SITL (1fa4ac2) on MacOS Intel

Linux and Windows version are ok.
Example on kali vm:

$ /usr/lib/inav-configurator/resources/app/resources/sitl/linux/inav_SITL --serialport=/dev/ttyACM0 --serialuart=3 --fcproxy
