Please try this - 

1. In your Applications folder right click on the Sims 4 app and select Show Package Contents.
2. Navigate to Contents > Mac OS.
3. There should be two files in there. Right click on The Sims 4 and select Move to Trash. Don't drag the file as it will only move an alias and leave the original in place. Leave the other file, The Sims 4.par alone.
4. Now open Origin, click on The Sims 4 in your Games Library and click on Download.
