My sims 3 64 bit stuck on the loading screen

@classicacosta  Please start with a clean user folder, with no mods or custom content.  I know you want to keep your mods and cc, but it's easier to go piecemeal at this point.  Move your entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, open the launcher to spawn a clean folder, and try loading a new save, just to make sure it still works.  Do not add any mods or cc yet.

If the new save loads, copy the backup version of your problem save to the new folder and see whether it loads.  Don't add any other content unless this "SV updated" takes place in a different version of Sunset Valley, in which case install only that world, nothing else*.  Let me know whether this works, and we can go from there.

If you happen to use AwesomeMod, you'd need to install it too, because saves that have been played with it may not work if it's removed without the proper procedure.  But please try at least once without any other content.

Hey so i did that! loaded a new world however on the loading screen my screen started glitching. So I'm guessing there's something wrong with the game itself or maybe my computer isn't compatible with it?

All mods and all CCS were removed! 

@classicacosta  Did you change any of the graphics settings?  If you did, please delete options.ini from Documents > Electronic Arts > The Sims 3 and try again, this time leaving the options at their defaults.  If that doesn't help, or you didn't change the settings, try switching to windowed mode at the Main Menu before trying to load a new save.

If that doesn't help either, please attach your deviceconfig.log to a post; it's in Documents > Electronic Arts > The Sims 3.  (You'll need to manually open the folders; the file won't show up in a search.)  You can delete your user and computer names, about 25 lines down, but there's nothing else in that file that can identify you.

And a screenshot or video of the issue would be helpful.

Ok I'll try these! I've already been playing in windowed mode however, but I deleted options ini so I'll how that works and let you know! Once again thank YOU SO much!!

Ok, so I attempted to open a new save in a new world that I had not updated and the loading screen went completely black in this case I still have my older folder with mods in the game. I attempted to do the same thing except i took out the mods this time and i was still stuck on the loading screen. In this step I did remove options.ini like asked! So I will now be doing the following steps after. 

here's my device log: 

Ok, so I actually I just tried to do this again with a clean folder and the new save did load!  And then I added my problematic save to this new, clean sims 3 folder and I was stuck on the loading screen. I tried to load my other problematic save (SV Updated) and I was able to get past the loading screen!

@classicacosta  It would be odd for those mods to cause the issue, unless you have other mods that conflict.  It should also be noted that you would need the StoryProgression base mod for the Money and Relationship add-ons to work.  If you'd like to troubleshoot further, I'd be interested to know which mods you currently have.  But if you're satisfied, you don't need to spend any more time on this issue.

@classicacosta  Personally, I would add NRaas ErrorTrap and Overwatch for general maintenance, in fact I'd never play a save I cared about without them.  As far as your current mods go, none of them should conflict with any of the others or with the ones you removed.  It's possible that something went wrong temporarily with the features of one of the mods and that removing it removes the problem, letting your save load properly.  It's also possible that you have an outdated version of one of the SP add-ons, which would be an issue.

In your position, I'd go in steps, using "save as" to rename the save, and quitting to desktop, deleting the cache files, and reloading to test after each one.  That way, if you add something to your save and it stops working again, you can easily revert to the next newest save without losing much progress.  This is how I'd approach things:

• Either download new copies of your currently installed mods, so you know they're up to date, or check the version numbers against the ones posted on the NRaas site
• Add ErrorTrap and Overwatch
• Download fresh copies of SP Money and Relationship and add them
• Download fresh copies of the other mods you removed and add them one at a time

It's important to play forward and save (using "save as") so that all traces of the mods you removed are gone by the time you add them back.  While none of these mods should cause the issues you've seen, it's always possible that something weird happens.  Now that you can in fact load your save under certain conditions, there's not much harm in experimenting as long as you don't save over the working copy.

@puzzlezaddict Thanks so much for all the help! I'm definitely gonna try these tips! Can't thank u enough!

HERE are screenshots!

@classicacosta  This is kind of a difficult problem to address.  One possible cause of the graphics glitches in your screenshot is changing the graphics settings while you have a save loaded, or changing them at the Main Menu and then immediately loading a save, without quitting first.  So don't do that, or if you have, delete options.ini (again) and let the game create a new one.

It should also be mentioned that deleting the WorldCaches files in Documents > Electronic Arts > The Sims 3 can have significant negative effects in the 32-bit version of Sims 3 for Mac; I don't know if those have carried over to the 64-bit version, but don't delete those files either.

It would be unusual for custom content to produce this issue, but you should still try playing without it, just as a test.  Use "save as" to rename your save, so your original remains intact with all its cc still present, then load the game without cc a couple of times to see whether it helps.

Another possible cause of the glitches is that your graphics chip or its driver doesn't seem to work well with Sims 3.  I'm not sure why, but you're one of a number of players with this particular class of processor and graphics chip with significant graphics issues.  If this is the underlying cause, there's not much you can do about it except hope Apple releases a more cooperative driver, which would be bundled with the OS.  (So keep your operating system up to date.)

It's also possible that there's a problem with your laptop's hardware.  I certainly can't diagnose it from here, and I don't even think it's particularly likely, but I want to mention it just so you're aware.  If you have the ability to take your laptop to an Apple Store to get it checked out, it may be worth doing so, if for no other reason than you'd be able to stop wasting your time troubleshooting what turned out to be a hardware issue.  If you can't get to a store right now though, don't worry about it too much.
