@cjones13 The workarounds that you need are creating an alias for any packs that don't already have them, copying files from the folder of one pack to another, and editing your .sgr files.
Depending on your computer's specs and which packs you have installed, you may or may not need to do all three steps. If you could post this information, we could help you get the game running on your mac.

The only game I installed was the main game. When I launch it I don't even get the Sims 3 plumbob, I only get the Unknown Error message.
@cjones13 Since you can't even run the base game, you'll need to edit the .sgr files. But there's someone who can help you with that, if you want. Bluebellflora is great with this kind of thing, and she's around right now, if you're interested. Just post here:
@OceanGRose Since there are so many different issues with Sims 3 in mac OS, I'm not sure which problem you're referring to. But the video is probably this one, which shows how to move files from certain incompletely installed packs into the folder of your newest pack by release date:
This is only one of the fixes for the unknown error. If you've installed any of Ambitions, Late Night, Fast Lane, and Outdoor Living, and at least one of those four packs is not your newest (by the date EA released it), then you'll need to apply the fix in the video. (If, on the other hand, you only installed one of those packs, and it is your newest, then you could skip that step.)
These four packs usually don't have their own aliases in Applications, alongside the alias for the base game, so you'd need to create one for each of them as well. But that's simple:
If these steps don't help you, the problem may be your graphics card—some are not supported by TS3. In that case, you'd need to edit the game's .sgr files to force it to recognize your card. If you'd like help with this, or you're not sure whether it's necessary, please list your computer's specs here, as described in this post:

That video only describes the fix for one of the six different causes of the unknown error message, and doesn't cover all the details about that one approach, either. Luckily, Bluebellflora wrote a comprehensive guide to installing Sims 3 in macOS. It's in her master help thread pinned to the top of this forum, or you can find the guide in this post:

I have never played TS3 on this laptop as it is pretty new, but here's my issue. I downloaded and installed TS3 Starter Pack from Origin, download and installation went fine. Then I tried to launch and it wouldn't get past the blue screen with the plumbob without an error. So I followed Bluebellflora's directions and now I get the unknown error popup and can't even get the game to launch at all. I have uninstalled and reinstalled twice now, but not through the uninstaller, as my game doesn't even show up as an option to be uninstalled, so I moved all the folders and add-ons to the trash. I am unsure what to do at this point, if the game is just not compatible for my laptop then I guess I'll just have to deal with that but I used to play TS3 all the time on a desktop before my sister lost the disk. Any help would be appreciated. Below is the error I get and my computer information. Thanks.

@rhyeneldridge Your particular model Mac usually runs Sims 3 just fine, once a couple of steps have been taken to fix certain issues with how the game installs. Most people running Mojave find that they don't even need to add their graphics card to the game's database, although that's not too complicated if it turns out to be necessary. Hopefully you'll be able to skip that step though.
Please start by doing a clean uninstall of everything Sims 3-related. In case you didn't see this before, here's Bluebellflora's guide:
Install the base game only, and run the Super Patch to manually patch to 1.67.
Now try to launch the game. If you get an unknown error, let me know. If you get the license server error, that's fine, you can ignore it for now. Just install High-End Loft Stuff and Late Night, then create an alias (icon) for Late Night in Applications, alongside the alias for the base game. Here's how:
