Re: sims 4 Graphics card unrecognised after macOS Catalina update.

1. Open the GraphicsCards.sgr file using TextEdit (Right click/CTRL and click on the game in your Applications folder, select Show Package Contents then open the Contents folder). The first long list of GPUs will be ATI/AMD then NVIDIA. Scroll down until you get to the Intel section 

   vendor "Intel" 0x8086

2. Scroll down a bit further until you see the following section:
   

   card 0x1606 "Intel Broadwell HD Graphics M ULT GT1" $cardLevelMedium $resolutionMedium
   card 0x1626 "Intel (R) Iris Graphics 6000" $cardLevelMedium $resolutionMedium
   card 0x162B "Intel (R) Iris Graphics 6100" $cardLevelMedium $resolutionMedium
   card 0x1622 "Intel (R) Iris Graphics 6200" $cardLevelMedium $resolutionMedium
   card 0x1927 "Intel (R) HD 550" $cardLevelMedium $resolutionMedium
   card 0x1926 "Intel (R) HD 540" $cardLevelMedium $resolutionMedium
   card 0x1912 "Intel (R) HD 530" $cardLevelMedium $resolutionMedium
   card 0x191B "Intel (R) HD 530" $cardLevelMedium $resolutionMedium
   card 0x1916 "Intel (R) HD 520" $cardLevelMedium $resolutionMedium
   card 0x191E "Intel (R) HD 515" $cardLevelMedium $resolutionMedium
   card 0x1906 "Intel (R) HD 510" $cardLevelMedium $resolutionMedium
   card 0x1902 "Intel (R) HD 510" $cardLevelMedium $resolutionMedium
   card 0x5916 "Intel (R) HD 620" $cardLevelMedium $resolutionMedium
   card 0x5926 "Intel (R) HD 640" $cardLevelMedium $resolutionMedium

3. Create a new line below the  one for the 640 and enter the following: 

   card 0x5927 "Intel (R) Iris Graphics 650" $cardLevelMedium $resolutionMedium

4. Close the file, saving if prompted or it doesn't autosave.

Now launch the game to the loading screen then quit. Go into the Electronic Arts > The Sims 4 folder and open the Config .log file, scroll to the top and see if your card has now been found. Under the Graphics device info bit it should now correctly identify your card and show [Found: 1, Supported: 1].
