64-bit Mac please help me

Okay, I did that and then pressed play and I was able to get to the main screen. I installed all my packs after then went to test if it worked and then it quit unexpectedly again. 

For reference, I have World Adventures, Late Night, Generations, Pets, Master Suite, Seasons, 70s, 80s, & 90s, University Life, island Paradise and Into the Future. I've seen other posts where its mentioned that the Pets expansion pack may be the issue to some people's problem, do you think I should uninstall Pets?

@awkssimmer  Pets can cause issues on computers with only integrated graphics.  Your laptop has a dedicated GPU, so I wouldn't expect it to have the same issues, although I don't have a lot of data on your particular graphics card.  Regardless, the issues with Pets show up once a save is loaded; installing the pack shouldn't affect the loading process.

Please try playing in another clean folder.  If that doesn't help, please create a new admin account on your Mac and try playing in that.  Don't link it to your iCloud account (you can skip that step) or import any other settings.  Just open Origin and launch Sims 3, and let me know how it goes.

So I couldn't get it to play on another clean folder. I did create a new admin account and pressed play. None of my packs showed up on the launcher but when I had gotten in, it showed Isla Paradiso, Bridgeport, Sunset Valley, and Appaloosa Plains.

@awkssimmer  The packs not showing as installed in the launcher is to be expected when playing in a new account.  The files that tell the launcher you own the content are specific to each user account, and they don't copy or transfer on their own.  But it's not a problem for the moment; the only issue would be if you wanted to install Store or custom content through the launcher.

Does the game itself work now?  If so, the issue is on your main account.  In that case, please let me know how much free and total storage your Mac has and whether you've selected the option to optimize storage.  Please don't do this if you haven't already—that could cause more problems here.  Just check the setting and let me know either way.

Yeah, it still says that it quit unexpectedly on my main account. I have 499.96 GB of total storage on my Mac. I have 429.6 GB of free storage and the option to optimize storage is not selected.

@awkssimmer  But does the game fully work in the new account?  If so, the problem is something else in your main account, and in that case, try playing while your laptop is offline.  You can sign into Origin and put it in offline mode, then disable wifi before launching Sims 3.

If the game crashes in the new account, please move the Sims 3 user folder to the desktop (in that account) and try again.  I'd like to know whether you can get one play session out of a new folder before the game stops working, each time; or whether it's just permanently stopped working in the new account.

I tried playing on the new account and I got to the launcher and pressed play and it went back to Origin. No messaged popped up and I waited a minute or so. I put The Sims 3 folder on my desktop and tried again and did the same thing. Also tried while going offline and turned off the wifi and didn't work.

I tested going offline and turning off the wifi on my main account and it quit unexpectedly when I pressed play.

@awkssimmer  Do you use a third-party antivirus, and if so, which one?  What about a cleaner app?  The fact that the game worked once in the new account but not after is definitely strange.

If you want to try playing with no packs, in either or both accounts, you can drag the "The Sims 4 Packs" folder out of Applications or Users > your username > Applications, wherever it happens to be.  You'd need to do this from your main account if it's in the user Applications folder, but the change would then affect both accounts.

No, I don't use a third-party antivirus or cleaner app. 

I tried that on both accounts and it quit unexpectedly on my main account again and went straight back to Origin on the other account.
