Upgrade won’t install

OK, my 2010 MacBook Pro may no longer be state-of-the-art, but it’s no slouch either. Prior versions run, but the latest version gives an error that it does not support the graphics hardware on my computer. Heck I’ve not found a game that I can’t run because my computer is too old, why can’t I run a simple screen saver?
