Re: The sims 3 keeps spontaneously crashing on my brand new MacBook Pro
@mazeikaite Sims 3 isn't so broken as to be impossible to play, even in macOS, but it does have issues that need to be managed. Do you have any sense of what was going on when the game crashed this time? For example, what time of day was it, what were your sims doing, what else was on-screen (deer, wild horses, whatever), and so on?
Pets and strays can cause problems when trying to navigate stairs too, which is a problem in any world but especially in Appaloosa Plains. So it would be helpful to test in Sunset Valley, first with Pets still installed, and later without it. To uninstall Pets, simply drag the EP05 folder out of the "The Sims 3 Packs" folder, wherever it is on your computer: Applications, Users > your username > Applications, or Applications > EA Games.
The point is, if you can get the game running in a more or less stable manner, you can manage the features that cause problems. For example, you might find that you need to limit wild horses and deer, which is simple with a mod. Or you might need to remove the Pets expansion entirely, while the other content is fine.
