How to change the steps_per_mm value

[JayJayXPro]

Hi! How to change the steps_per_mm default value for X and Y axes in creator_pro.def.json file? I am trying to enter a value but something is not working for me ... I changed the gears and I have to correct this difference.

Additionally, I have mac os big sur so ReplicatorG or Pronterface don't work ... I want the change to be in config, not G-Code. Is there a way to do this?

I am not experienced in programming so please be understanding
