MacBook Pro 13" Late 2012 Model

Hello All,

Not sure if this is the place to post this but does anyone have any recommendations on which MacOS version I should use on my 2012 MacBook Pro?, Im wanting one that will allow me to install stuff such as Brave without having to use an older version of the app.

NOTE: I would also want to use 32-Bit apps as well so what would you guys recommend?.

Thanks :)
