Re: Sims 4 Lag on Macbook Pro
@pinkelise15 You're right, you should be able to run TS4 just fine on your computer. (I take it that lowering the graphics settings a bit doesn't help? It's worth trying, just to make sure that isn't the issue.) You might want to check how much free storage you have as well—click the apple icon in the upper left corner of your screen, select "About This Mac," and hit "Storage."
It's possible you have one or more mods or cc items causing trouble, or perhaps another file in your game folder is corrupted. The easiest way to find out is to drag your entire TS4 folder out of Documents and onto your desktop. When you launch the game again, a clean folder will spawn with no content. Play a new game in this folder, just to see whether the lagging persists. If it doesn't, you can start moving your saves and other content into the new folder from the old one, a few files at a time. Keep testing to make sure the game doesn't start to lag; if it does, you'll know that one or more of the files you moved over is a problem.
