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 – https://bluebellflora.com/fix-for-incompatible-graphics-for-the-sims-3-on-mac/


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”
          If this will not work for you add your specific Intel chip number. For example, if you have the Intel Iris Plus 640 add “IntelIrisPlus640”
        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.

  4. Please, I am desperate. I followed the steps and now my game runs on the lowest graphics and the options don’t save even if I change them. The device conflig log is blank, I reset it but it still doesn’t work. Please help, I followed all the steps, this game is killing me. I don’t want to reinstall all the EPs again, it takes like 6 hours.

      1. My game loads and I can open my last save but for example the map view is all purple and blank. None of the settings save no matter where I slide them. The log is empty.

        Edit:
        Now I put the cgr files back to their previous settings and so far I only got one error and things got back to normal thank god! I was panicking. but the thing is: my mac’s graphic card is so much better than what I get and despite following your instructions for the Intel Iris Plus to the letter it still doesn’t recognise my cars and gives me crappy results. Is this because I run this game on a mac?

          1. Alright, I understand. Thank you so much for your help and quick reply. So is there a substitute card I could put in the cgr file instead of IvyBridge so that I at least get some better results? Or is this the best the game can do on a mac 2017? My biggest concern is that the buildings in all my towns, no matter if they’re fanmade or eaxian, are blurry and the details take a while to load while my sims travel the town. This lack of detail makes some custom towns unplayable for example, because the details of the town are beautiful but I can’t see them in the real time. I hope my description makes sense. Thank you for your patience.

          2. Perfect sense 🙂 the fix isn’t perfect but at least makes the game playable. You should be adding IntelIrisPlus into the .sgr file, not IvyBridge… unless you have a different Mac to one listed above?

  5. That’s the problem, changing the .sgr for IntelIrisPlus completely messed up my game (I couldn’t log in before, the user Malene is me). I changed the file exactly like in the instructions above, put my device ID 0x5926, edited both files. When I started the game it launched and I could load my save but the graphics were the lowest possible, the options reset and they didn’t save despite launching the game a couple of times and the file deviceconfig.log was always empty. The game was laggy and the town view was blank and purple. So I change it all back to IvyBridge so that I can at least play.

      1. It worked! IntelIrisPlus640 [Found: 1, Matched: 1] !!! Thank you! 🙂 Brilliant idea, I’m so ready for my new beautiful graphics! Everything seems to be sorted out. Do you think I should change the sgr files in all my EPs folders too? Or should I leave them alone?

        1. Great! And thanks for letting me know, all feedback is hugely appreciated and helps others too. I’ve added this info into the post 🙂 If your game works ok now I wouldn’t mess with the packs but if it’s still borked then yes, edit them.

  6. I did all of the steps, but when I load the game I can’t see some things. Like options show that they are there and highlight when I put my mouse over it, but I can’t see any words or images. Is there a fix for this?

  7. Hi! I really appreciated all your information. However, mine is still not working. 😦 I still get ‘unknown error occurred’ when I tried to launch the game on Origin. My macbook is 2017 15″ MacBook Pro with Touch Bar. There are two graphics cards. Intel HD Graphics 530 & Radeon Pro 450. Could you help me?
