Complaint regarding persistent lag issues on M-series MacBook.

I play The Sims 4 on MacBook Pro M5 Pro with 48GB RAM, macOS Tahoe 26.5.1.

The game runs with heavy lag, especially when saving while online.

I removed ALL CC, cleared all cache and exception log files, but the problem persists.

After editing a Sim, the loading screen spins infinitely. No system warning sound on Mac, game stuck forever.

In addition, only a few minutes into gameplay, if I leave the current lot to go into the world and switch to another household, the game freezes completely. There is no response, I have to force quit the game.

I have tried repairing the game, switching to windowed mode and deleting localthumbcache.package. Freezing still occurs. This appears to be a Metal rendering compatibility bug for Apple Silicon Macs. Please fix this issue.
