[CURRENT ISSUE] Sims 4 crashing when travelling - ARM Macs only

After the update, I uninstalled the game (and all the add-ons!) and reinstalled it. Still froze on me after a few minutes.

Thank you for the good info!

Thanks for the info :) You're running 15.1, not 15.3 so maybe a bump up to 15.3.1 will help. Please do report back!

I've tried resetting the NVRAM, booting the game in Safe Mode

1. You cannot reset the NVRAM on Apple silicon Macs, that only applies to Intel Macs. Silicon/ARM Macs reset the NVRAM every time they are restarted
2. Starting up in safe mode will render the game unplayable due to not all the full Metal drivers being loaded. There's no point trying that.

I'm having the same issue. I played with no problems for a day or so, then my game started crashing. I have the M3 MacBook Air running macOS Sequoia 15.3, about to update to 15.3.1

I tried the windowed mode and to create a new folder, with my save. I also tried to play a new game completely, but I can't play for longer than 5 minutes without it crashing. My entire computer restarts.  I've tried resetting the NVRAM, booting the game in Safe Mode, but still having the same problems. It didn't restart my computer in safe mode, but it did freeze the game and I had to force quit TS4 and the EA App.

I just got this computer so I'm pretty frustrated.

1. are you running antivirus? NO
2. do you have the in-built firewall enabled? System Settings > Network NO
3. are you running a 3rd party antivirus? NO
4. do you have any apps running in the background? Please also check the top right of the menu bar for background processes/apps running When the issue began, I was running Spotify, but since then I've disabled it from running on start up
5. does Activity Monitor show excessive memory or CPU usage? Yes, the time I was able to check it was running at like 120% of CPU? 
6. how much RAM/Unified memory does your Mac have? 16GB
7. if you have lastCrash/lastException files in the TS4 folder please copy/paste here or provide a screenshot

1. raise the Mac off a hard surface placing books/DVD cases/something underneath the left and right sides to balance it (safely!) so as much of the bottom casing as possible is elevated and air can freely circulate underneath. Or if you have a USB cooling laptop stand thing use that. This will keep it as cool as possible.

Will do :(

lastException file is copied here (I couldn't get the attachment to show)!

I'm also going to update my OS and see if that changes things.

Bluebell812 which exact model Mac do you have - Apple > About this Mac - and which version of macOS?

ghostfawn 

Great! No need to feel silly. Big Sur should be fully compatible with the game. When you update the OS it also fixes any corrupt system files and broken links so maybe your OS was a little unstable and just needed some TLC :) 

I don't think the game mode has fixed it. Having that enabled isn't fixing it for others. Hopefully it won't break again....

Software update worked for me!! Feeling a little silly now, should have tried that first lol. Not sure if it maybe has something to do with the "game mode" in the new Mac OS helping out with performance? Either way, everything seems to be running fine for the time being - thanks Bluebellflora for the help!

Not really sure TBH but worth trying. My M1 MBA is running Sonoma 14.7

Thanks! Current version of Sonoma is 14.7.3. Do you want to update the OS and see if it helps? Mine is running fine on 14.7

Few more questions for you all:

1. are you running antivirus?
2. do you have the in-built firewall enabled? System Settings > Network 
3. are you running a 3rd party antivirus?
4. do you have any apps running in the background? Please also check the top right of the menu bar for background processes/apps running
5. does Activity Monitor show excessive memory or CPU usage?
6. how much RAM/Unified memory does your Mac have?

So far in this thread, from those who have been specific, we have all ARM MacBook Airs and one ARM Mac mini, although the Mac mini could be a display issue, waiting for Itsfrank4you to confirm. The MacBook Airs don't have a fan so as always I'm wondering whether this could be an overheating issue where the OS is throttling processing power to the game in order to protect the Mac from overheating. Major graphics improvements were made to the game in the 14 January patch which may have made it more greedy for power although I was hoping the opposite is true:

Performance and Memory Improvements

• Smoother Gameplay - We’ve optimized mouse movements, preventing slowdowns and making gameplay more responsive on PC, Console, and Mac.
• Improved Graphics and Performance - On Mac and PS4, we’ve optimized how graphic data is handled, resulting in smoother and more efficient rendering and overall performance.
• Memory Efficiency - Various enhancements have been made to save memory across all platforms, helping the game run more smoothly and reducing crashes.

Hi,

Macbook Air owner here, Sims 4 started crashing, switched to windowed, still crashed, did the Sims 4 copy-around as described by Bluebellflora -- still crashes in both windowed and fullscreen; has no mods -- but plenty of expansion packs. Macbook is an M1, 16GB ram, MacOS Sonoma 14.6.1 -- it didn't do this prior to the January 2025 update.
