We hope you weren't determined to run The Sims 4 on the same PC you had when it came out in 2014. The developers have warned that the life simulator will end support for 32-bit operating systems and non-Metal Macs in June 2019. Simply put, it's about "growing, improving and optimizing the game." And for Mac users, it's virtually necessary. Apple started deprecating OpenGL visuals as of macOS Mojave, and Metal is the only way EA can guarantee cutting-edge performance and features going forward.
