PowerTunes

PowerTunes is a utility for managing multiple iTunes libraries on the same Mac. It allows users to create new iTunes libraries, switch between existing ones, copy playlists and individual tracks between libraries while preserving metadata (play counts, ratings, EQ presets), merge libraries, and move media between drives or network locations. The app was designed for users who maintain separate iTunes libraries for different music genres, personal and work content, or performance optimization on older hardware. PowerTunes functioned as a companion to iTunes in the late 2000s and 2010s.</description> <parameter name="recommendation">PowerTunes was last updated in 2010 and no native Apple Silicon build has ever been released. The app was built specifically for iTunes as it existed in that era — a music player and library manager that Apple has since replaced with the Music app. iTunes has not existed as a standalone app on macOS since version 10.15 (Catalina, 2019), when Apple split iTunes functionality between Music, Podcasts, TV, and device management tools. The app runs under Rosetta 2 today but will stop launching entirely when Apple removes Rosetta in macOS 28 (late 2027). The Music app in modern macOS handles multiple library switching natively (Library menu → switch library), so most PowerTunes workflows have built-in alternatives. If you rely on PowerTunes for complex library management, merging, or metadata preservation across multiple iTunes backups or archives, consider whether the Music app's native library switching, or third-party tools like Pacemaker, suffice for your current workflow — but plan to transition away from PowerTunes before late 2027 when it will no longer run.
