Remastered for Mac - Max resolution setting 1440 x 900!?

hi all.

I downloaded HW Remastered from the App store after seeing it’s there, and hear it was stunning in hi rez settings. Now I’ve downloaded it, the max it’s letting me select is 1440 x 900!? Surely this can’t be correct? It’s super blurry on my max spec Retina Macbook.

Surely I’m not the only person to experience this?

Appreciate the help
