Mac M1 Unexpected Quit/Crash

@stratuscloudx  Sims 3 crash files are mostly useless, but if you use mods and happen to have scripterrors, those could be more helpful, at least for people who can read them.  So hang on to those if you see any.

What world(s) are you playing in, and do you use mods or custom content?  Is there any pattern to the crashing, for example when something happens in-game?  The next time you play, please also open the Activity Monitor (in Applications > Utilities), switch to the Memory tab, and double-click on the Sims 3 entry once you've launched the game.  You can position the window that appears so you can see it while you're playing; keep an eye on it and let me know how much real and virtual memory it reports the game using, especially right before a crash.

The worlds I've been playing in (recently) are Appaloosa Plains and Moonlight Falls, both of these worlds I've experienced a crash in with my current settings. In the past have also crashed in Sunset Valley and Starlight Shores. 

My two recent crashes have happened right when something is about to happen. One has happened right before my sim enters their friends house from school after getting off the school bus. The second happened with a witch casting a fire blast spell on another sim. (I've done both of these again to see if the game would quit but it didn't).

I use Nraas Error Trap and Overwatch and they do have script error files if that would be any help. 

@stratuscloudx  I think the best move here is to post on the NRaas site—Chatterbox is fine—asking what the scripterrors mean, if anything.  You can drag and drop the files themselves directly into the text window when creating a post; or if you have a number of them, zip them together, upload them to a free filehosting site (Google Drive, Dropbox, etc.) and link them.  I'd offer to read them myself, but I have only basic skills in that regard.

If you see any files that just list a bunch of removed items or simdescriptions, those are correction logs and can safely be ignored.  Most of us get one or two of these almost every time we load a save.  It's the other ones, those that list a sim and a planned action and say something that sounds like why that action couldn't be performed, that are of interest.
