When I run the command "./gcclassic > GC.log &", terminal response in following:

by the way, "input.geos.txt" doesn’t generate.

Thanks for writing @Chuanhui0601. We don't have a lot of experience running GEOS-Chem on a Macbook Pro. I am not sure the fullchem simulation would work but maybe simpler simulations (with less species) like the carbon simulation or the TransportTracers simulation would.

Also, on MacOSX, the maximum stack memory is 65532 bytes. This might not be enough to run a GEOS-Chem simulation.

If you have access to a machine running any flavor of Linux, I would try that. You can also run GEOS-Chem on the AWS Cloud as described at https://geos-chem.readthedocs.io.

@Chuanhui0601 I forgot to mention that the "stack" is the area of memory where the computer will store local subroutine variables (those that aren't declared with SAVE, or those not at the top of a module) as well as any parallel loop variables declared !$OMP PRIVATE or !$OMP THREADPRIVATE. Because of the low limit on MacOS, this may prevent you from running a GEOS-Chem simulation.
