GDXin in Mac system

GAMS
1

Dear all,
I realised gdxxrw not functioning in Mac system… But after I got a done gdx. file from others,
I tried to read it in in my code, it doesn’t work. and seems can’t find the file (I checked carefully, it was there, in the same folder of .gms file!)

*$call “gdxxrw upload_data.xlsx @temp.tmp o=Data_input”;
*$include “demand.csv”;
*$if not exist demand.csv $abort.noError Data ist not present!
*$call csv2gdx demand.csv output=Data_input.gdx fieldSep=Comma useHeader=y id=d_upload;
*$call csv2gdx renewable_share.csv output=Data_input2 fieldSep=Comma useHeader=y id=phi_res_upload;

$gdxin data_input.gdx; //here, wrong, with “no such file or directory”…
*$load Data_input.gdx;
$load d_upload phi_res_upload;

Any one shed some lights, many thanks!

Environment: GAMS Studio 33 @ MAC… Catalina, Version 10.15.7
