Sims 3 Mac sound delay and crashes

gk0604xm7y0o​  It's interesting that you get a sound delay around the Showtime concerts.  Some users have reported that anything Showtime-related produces no sound at all, but I hadn't heard of a delay.  This kind of thing is usually a sign of the game engine getting overworked, but an overworked game engine also usually causes other symptoms, so it's a bit puzzling to me.  On the other hand, if the problem affects all sounds once you reach a certain threshold, that could be a limitation of the engine.

If you notice a pattern to the delays when you aren't hearing anything from Showtime, please let me know.  It could be seemingly completely unrelated, for example maybe it's worse when the weather is bad (rain/snow/hail) or when you have a certain number of sims on the active lot.

The problem with Pets is not really the active household or anything that happens in it.  The biggest problems are baby animals trying to route where they can't go, for example up or down stairs; and horses trying to route anywhere given the space they need, or even just the strain of rendering them.  So you may only notice a problem once you've been playing for long enough for these effects to show up: when other households have adopted pets or horses, or when you start seeing them around.
