Help! Script mod(?) and CC content not showing up in game.

[snails231]

This is my first time using mods, and for some reason the script mod and the CC content I've tried to mod aren't working? I've tried repairing, updating my game, redownloading, and nothing's working? I've included pictures of everything too- please help. Before this, I tried using the MC commands, but it also wasn't showing up/working.

1. Check you have CC and Mods enabled in the in-game Game Options
2. Check all CC and Mods end in either .package or .ts4script file extension
3. Check your Mods folder is in the right location: Macintosh HD⁩ ▸ ⁨Users⁩ ▸ ⁨[your user account] ▸ ⁨Documents⁩ ▸ ⁨Electronic Arts⁩ ▸ ⁨The Sims 4⁩ ▸ ⁨Mods⁩
4. Trash the localthumbcache.package file in the Sims 4 folder
