That's not looking good. MacBook Airs aren't designed for gaming at all so it is probably struggling with the higher requirements of the game. Have you made sure that air can circulate underneath your Mac so it doesn't overheat and burn out the Intel graphics chip?
More info about your Mac would also be helpful, please can you 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
Yeah no problem:
macOS Mojave
version 10.14.16
Macbook Air (13 inch, early 2014)
Processor 1.4 GHz Intel Core i5
Memory 4GB 1600 MHz DDR3
Graphics Intel HD Graphics 5000 1536 MB
It fixes the issue but is rubbish quality it’s been working fine for years 🙂
