Hello, I have followed all the instructions, both from the provided link and with the help of ChatGPT+. I was not able to run the files on Mac at all.

Is it possible to get a refund? Or perhaps a video tutorial or further installation explanations?

Oh, did you get any error messages? 

Yeah, Macs can be a pain in the ass sometimes.

For a refund you have to  contacting support . It's not something I can issue personally.
