Sims 4 audio crackling or system freezing on Macs with M1 chip

The shiny and beautiful Mac with the M1 chip can run the Sims 4 beautifully even though the game isn’t native and requires Rosetta to run. There are two small niggles though which I’ve been a bit tardy about reporting here – sorry!

Freezing resulting in Mac restarting
I posted about this last November but just reiterating again. If you are experiencing freezing whilst playing, usually in CAS, just enable vsync in the game options at the main menu or open the Options.ini file in your Sims 4 folder using TextEdit, find the line for verticalsync and change the value to 1.

In-game audio crackle
This is pretty irritating and there doesn’t seem to be a fix apart from muting the sound. There is a thread here at Answers HQ so it’s worth subscribing to it if you want to see any updates.

Initialization at startup error – April 2020 patch issue for Mac

The Initialization at startup error [135dec40:90f690cf:00000075:495f32a0] is back with a vengeance, this time affecting Sims 4 Mac players running the current version of the game with multiple language options and not the Legacy Edition.

There are three options currently to fixing this issue. I’ll link directly to MaxisJoe’s workarounds at Answers HQ. Please read them fully and choose the one you feel most comfortable with:

Method 1 (Easiest option) – Change Origin and Sims 4 language to the same in the Origin app

Method 2 (More technical but still easy option) – Manually edit the .plist Origin files

Method 3 (Easy but drastic) – Uninstall and reinstall the game and change language in Origin

Issues playing The Sims 4 on 16″ MacBook Pros

Update 24.09.20 – joho1144 has posted a fix on the Answers HQ thread. Disable automatic graphics switching in System Preferences > Energy Saver. It seems as if the Mac is switching to the integrated Intel chip whilst the game is loaded when it should only be using the dedicated AMD GPU.


Seen quite a few posts now from Sims players with the 2019 16″ MacBook Pro whose games either crash constantly or have dreadful graphics with appalling screen tearing. The Config.log files are showing that the AMD Radeon Pro 5300M and 5500M are now supported but there are still issues. Symptoms may be:

  • Screen tearing
  • Game crashing, especially when trying to load a household
  • Flooring disappears and the terrain is visible
  • Black lines and patches in the game window

There are a few things that have worked for users and definitely worth trying:

  • Disable iCloud Drive in System Preferences
  • Disable Retina display in the in-game graphics options
  • Enable Vertical Sync in the in-game graphics options

You could also try toggling between fullscreen and windowed mode by holding down CMD, CTRL and F.

We have a thread running at Answers HQ for these issues too, please take the time to post your problem and click the Me Too button in the opening post so EA see it 🙂
