@GingerjuggernautThe basic problem is a bit to weak the graphics card that "borrows" memory from the system. It has 32MB dedicated memory. Requirements The Sims4 for the card is 128 MB of dedicated memory
I can suggest that you switch off all running programs in the background that you do not need during the game. In the first place turn off graphical programs and reduce the graphics requirements in the game options.
It doesn't help also that you have really old graphics card drivers - 8/27/2015. You need to download new drivers and install them
https://downloadcenter.intel.com/You also have a problem with either the Apple iTunes application or with your Net framework - itw_scrobbler.dll file is missing or corrupted. If a simple computer restart will not remove this error the best way to fix it is to reinstall this application
I don't know how it affects the game, but if you want to check whether your net framework has no errors here is the Windows tool for it. (I wouldn't want to use this Apple application on Windows but this is just my private opinion.)
