Re: Mac- Initialization error at startup
Legacy is not designed to fix the game, it is for Macs that do not support Metal due to older hardware and cannot run the current version of the game. I'm also assuming you don't mean Sims 3 (LE is TS4)
As you know there are a lot of threads on this issue but I'm going to suggest you try something different - completely uninstalling and reinstalling:
- Back up your Sims 4 folder
- Move your Sims 4 folder out of the Electronic Arts folder to somewhere different
- Right click on the game in your Origin games library and select Uninstall
-
Run the Origin reset tool
- Trash the Origin app
- Empty the trash and restart your Mac
- Download and reinstall Origin - make sure you allow access when OS dialogue windows prompt you
- Disable automatic updates in Origin
- Reinstall the game - make sure you allow access when OS dialogue windows prompt you
- Launch the game without any of your previous content
This might not fix it, but it is something to try that no one else has got back to me about yet and will get rid of the Legacy download you installed, always a bonus.
