The EPUB Spotlight Importer is a system component embedded in macOS itself, not a standalone application. There is no separate native Apple Silicon build to download or update. Spotlight's indexing plugins are handled by macOS during system updates. If you are running a current version of macOS on Apple Silicon (macOS 12 or later), Spotlight itself is natively compiled and will use native system plugins. If Spotlight is reporting the EPUB importer as Intel-only, the most likely cause is that you have not updated macOS to a recent version. Open System Settings, navigate to General → Software Update, and install the latest macOS your Mac supports. This will bring Spotlight and all its built-in indexing plugins — including EPUB support — up to their native Apple Silicon versions. If EPUB indexing still does not work after updating, you can verify the plugin's status by opening Terminal and running `mdimport -r /System/Library/Spotlight/` followed by `mdimport /System/Library/Spotlight/` to rebuild Spotlight's database. For comprehensive EPUB reading and library management, consider pairing Spotlight with a native EPUB reader like FBReader (available on the Mac App Store or directly from fbreader.org), which runs natively on Apple Silicon and works seamlessly with Spotlight indexing.
