sims 4 crashing on startup after maxis logo

@Peanutjelly231  The Sims 4 errors in your dxdiag are typically related to another program conflicting with the game.  For example, many players run Razer software and need to shut it down before launching the game.  I don't see any Razer devices listed in your dxdiag; I'm just saying that's the type of software typically implicated.

Anyway, try playing in a clean boot:

When you reboot, go through the Task Manager's background processes list shutting down anything that doesn't absolutely need to be running.  If you accidentally kill the wrong process and it doesn't restart itself, just reboot your computer.

It's not relevant here, but your Mac's memory is user-upgradable.  If you're considering it at some point, you'd save a lot of money by buying compatible but not Apple-branded RAM and installing it yourself, which is extremely simple.  Here's a guide from Apple:
