Restrict access to books and audiobooks with explicit content in Books on Mac
You can prevent people who use your Mac from accessing the Book Store or Audiobook Store and from getting books with explicit content. If you set up Family Sharing, you can turn on Ask to Buy so that you’re asked to approve purchases for certain family members.
