Hi,
Thanks for the answer and other option.
I do not any graphic cards on this Mac because it is a MacBook Air. If that is a requirement, I will try the other option you mentioned. Other info about my Mac:
Model-ID: MacBookAir5,2 ( of Mid 2012)
Processor name: Dual-Core Intel Core i5 ( Not Apple M1).
I have a Linux PC where I will try it then before I go with the RenPy.
Thanks again :)
