7 Best EPUB Readers for Mac in 2026 (Free & Paid)

Apple Books ships with every Mac. It opens EPUB files instantly, syncs across your Apple devices via iCloud, and handles highlights and notes without setup. For most Mac users, it's already installed and works fine.

But Apple Books locks you into the Apple ecosystem. Your library doesn't sync to Windows or Android. Calibre manages thousands of ebooks with format conversion and metadata editing. Thorium Reader provides accessibility features Apple Books lacks.
