@streakmachine Along the lines of my 2008 15-in MacBook Pro. It maxes out at El Capitan as well. I acquired it for $500 from a pawn shop in 2013 & it was running Leopard on 2 GB of RAM.
First thing I did was add 4 GB RAM, then last year a 240 GB SSD. Totally transformed. And, being pre-Unibody, it has the “proper” keyboard.
