The Sims 3 Unknown Error Occured Issue on Mac - HELP!!
- 7 years ago
@ellamaree8 There are several causes for the unknown error messages, and it sounds like you will need to deal with all of them. The pack-related issues are due to the OS being incompatible with the game; the problem started with El Capitan and is still present in High Sierra. The base-game-only error is due to TS3 not recognizing your graphics card because its database hasn't been updated since 2013.
Hopefully you manually cleaned out the lingering TS3 files when you uninstalled the game (the uninstaller can miss some), but if you haven't, now would be a good time to do so. Then run the Super Patch (digital download version) to patch the game to 1.67, as the launcher isn't equipped to handle the data from all the patches at once.

Bluebellflora can try to help you get your graphics card recognized, although there's no guarantee that it will work. In addition to your specs, she needs the device ID of your card. You can post here or on her website. Here's how to find the relevant information:
