The iTunes 12.7.5 update has been released alongside iOS 11.4, tvOS 11.4, and watchOS 4.3.1. Apple has a macOS 10.13.5 update in the works, but has not released it as of yet.
iTunes 12.7.5 can be downloaded from the Mac App Store for free using the Software Update function.
iTunes 12.7.5 comes two months after Apple released iTunes 12.7.4, an update that introduced a new music video experience for Apple Music, adding a music video section to Apple Music in iTunes.
iTunes 12.7, released in September, was the last major update to iTunes, eliminating the built-in App Store to focus solely on music, movies, TV shows, podcasts, and audiobooks.
