Re: Sims 4 is extremely slow and laggy & gallery items are corrupted [MAC & EA APP]
"I can't check my graphics card since I have a MacBook." Absolutely not true. Please provide more information about your Mac. Instructions on how to do so and what to provide here - http://answers.ea.com/t5/The-Sims-Mac/READ-FIRST-Sims-4-Mac-Help-Guides-and-Troubleshooting/m-p/4612396/highlight/true#M162
The items in the Tray folder in the Sims 4 folder make up the households and Lots in the in-game Library. If those files are corrupted it may be causing the issue.
