@Miloev That's great news, and also very helpful to have confirmation that iCloud was (once again) messing with someone's ability to play.
For the graphics card, you're looking for a file called graphicscards.sgr, inside the game's program files. Those files will be in one of two places, either Applications or Macintosh HD\Users\[your username]\Applications. In either case, right-click (or hold down crtl and click) the Sims 4 icon, and select Show Package Contents. Open Contents, then graphicscards.sgr. If you're asked which app to use to open it, TextEdit works fine.
Right at the top of the file, you'll see this:
vendor "ATI" 0x1002
card 0x731F "AMD Radeon RX 5700 / 5700 XT" $cardLevelUber $resolutionHigh
card 0x15DD "AMD Vega 11" $cardLevelUber $resolutionHigh
card 0x6863 "AMD Vega FE" $cardLevelUber $resolutionHigh
Copy the text in this box:
card 0x7340 "AMD Radeon Pro 5300M" $cardLevelUber $resolutionHigh
and paste it directly under the first line above, so you'll now have this:
vendor "ATI" 0x1002
card 0x7340 "AMD Radeon Pro 5300M" $cardLevelUber $resolutionHigh
card 0x731F "AMD Radeon RX 5700 / 5700 XT" $cardLevelUber $resolutionHigh
card 0x15DD "AMD Vega 11" $cardLevelUber $resolutionHigh
card 0x6863 "AMD Vega FE" $cardLevelUber $resolutionHigh
(with the spaces in front of each line that this site is not saving when I paste)
You can see whether it worked by checking the same info you pasted here. You should now see a [Found: 1, Supported: 1] value.
Keep in mind that you'll need to repeat this process any time you repair or update the game, at least until your card is added to the file by EA. If it's easier, you can just copy the entire graphicscards.sgr somewhere else (right-click and select Copy, then right-click where you want it to go and select Paste) and replace the new version you get after an update.
