Problems with The Sims 4 on Macs with AMD Vega GPUs

The September patch seems to be wreaking havoc on Macs with AMD Vega GPUs. Users have reported crashing, glitched graphics and system lockups when trying to play the game. The affected Macs are:

  • 2017 iMac Pro.
  • 2018 15″ MacBook Pros. Not all these models will have Vega GPUs, it was an option at point of sale.
  • 2019 15″ MacBook Pros. This was the last model before Apple changed to 16″ screens. Not all these models will have Vega GPUs, it was an option at point of sale.
  • 2019 21″ iMac 4K. Not all these models will have Vega GPUs, it was an option at point of sale.
  • 2019 27″ iMac 5K. Not all these models will have Vega GPUs, it was an option at point of sale.

You can check to see which GPU your Mac has by clicking on the Apple in the menu bar then About This Mac. For 15″ MacBook Pros click System Report then look in Graphics/Displays you will have an integrated Intel chip and a dedicated AMD GPU.

There are currently three separate threads at Answers HQ which users are posting in:

If you are experiencing this on a Mac with Vega graphics, please head to the relevant thread and click the all important Me Too button in the first post. The more Me Toos, the more likely QA are to look at it.

No concrete workaround yet although lowering your settings to all low does seem to help. Try also switching to the Sims 3 camera if you are using the Sims 4 camera.

Sims 4 Packs not showing as downloaded in Origin since April 2020 patch

This isn’t really much of an issue as the packs are in fact downloaded and show up in the game but it is confusing some because Origin shows Download in the orange button instead of Play. The fix is super easy and requires creating a new folder in the Applications folder where the game is installed, and moving across a bunch of folders from the game app. Full instructions on how to do this are detailed in this thread at Answers HQ.

This is only relevant for users with an existing installation of the game. If you have installed the game since the 7 April patch you don’t need to worry about this as Origin has created the new folder for you.

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
