The Sims 3 64-Bit Keeps Crashing on Mac

@nessatay2223  What packs do you currently have installed, and what world(s) are you currently playing in?  I've probably asked you this before, but please list them anyway in case the answer has changed.

Hi @puzzlezaddict I'm hoping you'd be able to help me also. I've read a lot of threads already & I don't understand what's going wrong. I used to play this years ago on an old PC and found the box today so tried to put it on my Mac. I downloaded the 64-bit version from Origin. Every time I try to launch it crashes. I've tried to delete the version.tag file, didn't work. Tried moving sims folder to desktop, didn't work. Tried to update and repair game from Origin, didn't work. Tried disabling origin in game, didn't work. Origin also downloaded the late night, high end loft stuff, and island paradise packs but when it shows up on my game library it says they need to download again. From what I've read the packs aren't compatible on this 64bit version which I'm ok with but I can't even get the actual game to load. Also, I'm not sure these would interfere with this game being played since it seems to be a common issue with most macs and this game but a few years ago I did upgrade my logic board, battery, ram and hard drive. I greatly appreciate any help you could provide!

These are my specs- 

MacOS High Sierra version 10.13.6

MacBook Pro (15-inch, Late 2011)

2.2 GHz Intel Core i7

16 GB 1600 MHz DDR3

Intel HD Graphics 3000 512 MB

@6b62724f0a4d2139  Your Mac is a little too old to support Metal, which means it also can't run the 64-bit version of Sims 3.  You'll need to uninstall and then install the 32-bit version instead.

When you install Late Night, you'll need to apply a workaround to get the pack to work:

And when you install Island Paradise, you'll also need to copy some data from LN into a folder for IP:

High-End Loft Stuff installs properly on its own.

And please run the Super Patch (digital download version) to manually patch the game to 1.67.  The launcher doesn't always do a thorough job on its own.

Hi, I am having a similar problem. My game will crash after I save. I just updated to Monterey and my old save is in my game, but I think there are some issues with it. Here are my specs:

macOS Monterey Version 12.1

Macbook Pro (15-inch, 2017)

Processor 2.8 GHz Quad-core Intel Core i7

Memory 16 GB 2133 MHz LPDDR3

Graphics Intel HD Graphics 630 1536 MB

I'm not sure if Monterey will let me download the 32-bit version 

@krabby_pattiess  Do you use iCloud, is it syncing the contents of Documents, and if so, is it full or close to it?

My icloud storage is pretty full. I have 26.55 GB available out of 50 GB

@krabby_pattiess  That's not full enough to prevent the game from saving though.  Just in case it's this simple, have you been using the buydebug cheat?  The game will often freeze or crash if buydebug is still enabled when you try to save.  There's nothing wrong with using it; just remember to disable it when you're done.

Otherwise, as a test, please move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just start a new save and see whether you can save your progress without crashing.

If the new save crashes too, please temporarily disable the iCloud syncing of Documents and see whether it helps.  If the new save does NOT crash, please copy your existing save to the new Sims 3 folder and see whether it can save.  Don't move over any other content with the exception of a store or custom world if the save takes place in that world.

Let me know the results, and we'll go from there.

I have not been using buydebug at all. Just don't want to mess up my save, but honestly, it's okay because it's just one game I have been playing. How do I make a new folder without messing up my previous save? Or do you just want me to move the whole thing?

@krabby_pattiess  I want you to move the entire Sims 3 folder so the current save doesn't load at all, just as a test.  This folder or its contents can be freely swapped as necessary, so you won't break anything by moving files around.  The only reason your save might not load in a new folder is if it takes place in a store or custom world that you haven't installed into the new folder, and like I said, in that case it's fine to install just that world.

If you mean you don't want to mess up a save other than the one that's crashing, the same principle applies.  But if you prefer, you can instead put the entire original Sims 3 folder back when you're done testing.  I was just worried that the issue was something in the user folder rather than one specific save.

Now is also a good time to back up your saves, especially if you have one or more intact saves you'd like to keep playing going forward.  The user folder or some of its contents can become corrupt for any number of reasons, but with backups, you shouldn't lose anything for good.

I made a new save, and it did not crash! I backed up my old save. Could it be something with my old save?
