Sims 3 64 bits freezes and flashes

Hi, I’m having the same problem that @puzzlezaddict @is having and I tried to put in windowed size it’s still not working. I attached an image (I tried put video but isn’t working) of my situation, if you know something I can do to fix it please let me know! 
 

@Dangbe28  Please list the full specs of your Mac: everything under About This Mac including the operating system and except for the serial number.

laptop specs:

Macbook Pro 2020 13-inch 

MacOs Sonoma 14.4.1

Processador: 2.3 GHz Quad-Core Intel Core i7

Graphics: Intel Iris Plus Graphics 1536 MB

memory: 16 GB 3733 MHz LPDDR4X

Note: I bought this computer around two months ago!

@Dangbe28  Please go into Documents > Electronic Arts > The Sims 3 and delete Options.ini.  This will reset all your in-game settings, including the graphics options.  Load the game and don't change anything, with the exception of the resolution and fullscreen/windowed if you want.  Let me know how the game looks.

If you see any graphical anomalies, exit back to the Main Menu, lower all the settings to the minimums, disable Advanced Rendering and enable Object Hiding, quit to desktop, and reload.  It's important to always quit after changing a graphics setting (other than a couple exceptions) and before loading a save, or else you can see graphics glitches even when everything should otherwise be fine.

I will say however that from the few examples posted here, Macs with your family of processors, and I believe yours specifically has an i7-1068NG7, often run Sims 3 very poorly, with various graphics glitches that aren't responsive to intervention.  I'm happy to help you experiment, if you want to keep trying, just saying there might not be a good solution here.

Hi! it really helped me, thank you! 

Can i still install costum content/ Mods? or you don’t recommend it? 

Again, thanks for the help!

@Dangbe28  I would suggest being cautious with both mods and custom content, but there's no reason you can't use them at all.  Lighting mods are probably not a good idea, but any mod from NRaas is fine, as are most mods from Mod the Sims that say they're updated for patch 1.67.  You should absolutely test them out in a new save (other than NRaas mods) to be sure; I'm just saying you're unlikely to see any issues.

The same is true for .package-based custom content: test it in a new save to make sure it's okay, and actually use it on sims rather than just having it in your game.  If it's fine, keep it.  Even if you miss an issue, a .package file is simple to remove.

For .Sims3Packs, as in, what you install through the launcher, I'd strongly suggest testing everything in a clean user folder before letting it anywhere near your saves.  The problem here is that when you get bad cc this way, it's difficult to remove, so the best approach is prevention.  Move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop, open the launcher to spawn a clean folder, install what you want to test, and before doing anything else, see whether any extra items installed alongside the ones you wanted.  Bad cc can attach itself to other cc or to households or lots.

If you're satisfied you didn't get any stowaways, load a new save and check out the items.  Make sure sims are wearing them, or objects are placed on the active lot, and play for a little while, maybe a sim-day or so.  You can test a handful of items at once, to make this less tedious, as long as you remember to try them all.

If everything looks fine, you can then delete the new Sims 3 folder, restore the old one to Documents > Electronic Arts, and install the new content into this folder.
