@Miloev I've split your post into its own thread, since you have a different issue. (And yes, you're absolutely right that the Legacy Edition is not part of the solution.)
It's easy enough to get your graphics card recognized—you just need to add the card to the game's graphicscards.sgr file. If you'd like help with this, go into Documents\Electronic Arts\The Sims 4, open the file called config.log, and copy the information under "Graphics device info," about 25-35 lines down. Paste it here, and I'll write out the line you need to add to graphicscards.sgr.
The fact that you keep getting messages about an unrecognized card suggests that your options.ini file is corrupt or keeps getting replaced. Do you have iCloud set to automatically sync your Documents folder? If so, please disable it, at least temporarily. Here's how:

Having iCloud sync automatically might also explain the crashing. If disabling syncing doesn't help though, or if it's not the issue, please remove your entire Sims 4 game folder from Documents\Electronic Arts (you can put it on your desktop) and try to start a new save. Let me know how it goes.
Can you please help me too? my card isn't reconized.... I have followed your steps, and here is my info..

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].
Bear in mind that there are quite significant updates to the game for us Mac users and these changes won't stick (they reset anyway after a patch or repair) but hopefully your card will be added at some point 🙂 - https://answers.ea.com/t5/Technical-Issues-Mac/The-Sims-4-macOS-Notarization-FAQ/m-p/8876253
