We’ve detailed the steps on installing mods and CC below. (You cannot install or use mods and CC on consoles.) Our The Sims 4 guide will walk you through how to install CC and mods for both Windows and Mac. Installing them can be complicated if you’re new to modding games, but The Sims 4 makes it fairly easy. If you’re playing The Sims 4 on Windows or Mac, you can customize the game using custom content (CC) and mods.
