Intel Iris Plus – 2017 13″ MacBook Pro

This is the second part of a two part post detailing how to make The Sims 3 work on Macs with incompatible graphics. For the first part, go here –

Affected Macs for this workaround:

  • 2017 13″ MacBook Pro, two Thunderbolt 3 ports, Model Identifier: MacBookPro14,1 (Intel Iris Plus, Kaby Lake)
  • 2017 13″ MacBook Pro, four Thunderbolt 3 ports, Model Identifier: MacBookPro14,2 (Intel Iris Plus, Kaby Lake)
  • 2017 15″ MacBook Pro, non-Touch Bar, entry level 15″ (Intel Iris Plus, Kaby Lake)

Any and all feedback is greatly appreciated. Many thanks to Alex who provided the correct line for the Intel Iris Plus chips.

Firstly, we’re going to edit the GraphicsCards.sgr file that you should already have open. You will need your Device ID for this bit (I will be using a Device ID of 0x0000 as an example but you must enter your own Device ID):

        1. Scroll down to near the bottom until you see this: GCsgr
        2. Replace those highlighted lines with the following (using your own Device ID where I have put 0x0000):
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
          card 0x0000 “IntelIrisPlus”
        3. Save the file, overwriting if prompted to.
        4. Open the GraphicsRules.sgr file with TextEdit, the same way you opened the GraphicsCards.sgr file.
        5. Hold down CMD and press F to bring up the search bar. Copy and paste the following text into the search bar:       elseif (match(“${cardName}”, “*IntelIrisPlus*”)) GRulessgr
        6. Replace IvyBridge with IntelIrisPlus.
        7. Save the file, overwriting if prompted to.
        8. Now load up the game and set the resolution to one you’re happy with. If you can hear the game but not see it navigate to Documents > Electronic Arts > The Sims 3 and open the Options.ini file using TextEdit. Find the resolution setting and set it to:

resolution = 1400 900 0

You can change this later via the in game settings to whatever suits you but all affected Macs should support this resolution. Save if prompted.

If you install Expansion/Stuff Packs and the game stops working again you could try the following. Please bear in mind that I have not yet had confirmation that this works so always make copies of the relevant files so you can replace them if necessary. This is just a theory at the moment (feedback would be great):

  1. Go to Applications > The Sims 3 then right click on your most recently released EP/SP installed. For example, if you have University Life and have not bought any subsequent EPs/SPs then right click on University Life.
  2. Select Show Original then right click on the highlighted EP/SP that shows up and select Show Package Contents.
  3. Now navigate through to Contents > Resources > transgaming > c_drive > Program Files > Electronic Arts > (your EP/SP) > Game > Bin
  4. In the Bin folder you’ll see another GraphicsCards.sgr file and another GraphicsRules.sgr. Make the same changes to those that you did to the base game files.

If it still isn’t working, follow the steps above for every EP and SP you have installed. There may not be a GraphicsCards.sgr file in every Bin location. I wouldn’t add one but if your game still isn’t working then it wouldn’t hurt to try!

  1. I’ve completed all the steps but it still doesn’t work for me 😦 When I try to start the game, the message “unknown error occurred” pops up.


  2. I just purchased a new macbookpro touchbar. The game used to work with my old macbookpro 2011. Now nothing works. I have all EP and SP and I followed all steps for all of them and still, nothing works. I get the same message of “unknown error occurred”.


  3. Hi, it doesn’t work for me either.
    I have a Macbook Pro 13” w/ Touch Bar. I changed everything as in the guide, but nothing.

    I only have the base for now.
