Trying to use this on a old Macbook

Hi,

I am trying to find an old version of Kicad that'll run on my 2010 Macbook that is in incredible condition. Due to the old 2.4 Ghz Intel Core 2 Duo processor(and the fact that it's almost a decade old), it can't use current software. So, this is one of the few downloads of an older Kicad I could source. Now I've downloaded the main file and it gave me a folder full of the components and other internal code groups. I went in the folder to try and find the application itself, thinking that's how you open Kicad. Though, I wasn't successful so.... How do I open it? Do I a driver? Is this even Mac compatible? Because, I clearly have no idea.

                       Thanks for your time!
