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:

• iMac Pro thread
• 15″ MacBook Pro thread
• iMac thread

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.
