Love game but freezes computer

I love the game…I’ve been a fan since the original. What I’m noticing on my Mac is that it periodically freezes the entire computer up, and you end up with the pinwheel of death. The only way out is to power down the laptop and restart. Make sure you save often because of this!!! Other than that, the game is just as good as prior games. If that hiccup could just be fixed, I’d give 5 stars!
