Can't run simulation with FightGear in Mac

Hi,everybody.
I am tiring to make the simulation of FlighrGear with my mac. Although I do have installed FlightGear(2020.1.2), and I have found the file"fgfs" in the installed package(FLightGear->package contents->MacOS->fgfs) So the “fgfs” is not located in the same directory as in the ubuntu. And I can’t run it at the command line. I can just run it with double clicking the “fgfs” icon…It still encounters errors. Dose PX4 not support FlightGear for mac yet? Or is it just my setting problem?
here is the error message:

You should be able to start it from command line by right clicking on the fgfs icon and doing “Show package contents”. and look for the binary inside of there. Then you remember that path and use it to start from command line.

Yes ,I have found the “fgfs” in the package(/Applications/FlightGear.app/Contents/MacOS/fgfs)
And how could I make the px4 to start with the command:
make px4_sitl_nolockstep flightgear_rascal

I have tried the command with the specific path:
FG_BINARY="-- Applications/FlightGear.app/Contents/MacOS/fgfs" make px4_sitl_nolockstep flightgear_rascal

And it turns out to be errors:

Did you put in:
Applications/FlightGear.app/Contents/MacOS/fgfs ?

You need to add a / in front of it to make it an absolute path:
/Applications/FlightGear.app/Contents/MacOS/fgfs

Yes,I have tried,and it still can’t work, :firmware % FG_BINARY="-- /Applications/FlightGear.app/Contents/MacOS/fgfs" make px4_sitl_nolockstep flightgear_rascal

@kevindsp Could you post an issue on https://github.com/ThunderFly-aerospace/PX4-FlightGear-Bridge ?

To be clear, MacOS is not officially supported running SITL with flight gear.

@kevindsp why did you add the -- before the path? That’s wrong.
