Mac: Game won't launch with CC after Feb 2026 update
System: 2024 MacBook Air, M3 chip, 16GB RAM, 230GB free storage
I've been playing on Mac since s4 came out and according to the EA App - have invested 38,000 hours into this game and have never had this issue before! Ever since the most recent big update (feb 2026) my game is crashing/wont launch when I have CC added. The curser loads and then nothing happens and I have to force quit the game. I don't use script mods, only CC CAS & build/buy. All CC is from trusted, popular creators (TSR, well-known Patreon creators) and includes freshly redownloaded items that should be compatible with the current patch." Here is what I have tried to do so far:
-Repaired game through EA app - no change
-Removed mods folder - game opened but stuck on infinite loading screen
-Cleared all cache files in EA App and through Sims 4 folder (localthumbcache.package, cachestr, cachewebkit folders)
-Renamed entire Sims 4 folder to create fresh installation & restored saves folder - game works with NO mods
For mod troubleshooting I:
-Used Sims 4 Studio and ran batch fixes - didnt help
-tested a single mod - game works fine
-added old mods from backup - all batches crash on loading screen (tested with 50/50 method)
-Fresh redownloaded CC - initially works but eventually causes loading screen crashes
-Small batches of freshly downloaded CC - (10-20 items) eventually breaks the game again and just pulling the last batch out does not fix it.
Every crash seems to corrupt the current installation, requiring me to start with another new sims 4 folder and the then the process repeats when it eventually breaks again. Please help me with what i should do, I'm willing to try anything!
