If you are trying to install or fix iTunes on a Mac as of April 2026, here is the status and how to proceed: 1. iTunes has been discontinued on modern macOS

Starting with macOS Catalina (10.15) in 2019, Apple replaced iTunes with three separate apps: Apple Music: For your music library and the iTunes Store. Apple TV: For movies and shows. Apple Podcasts: For podcast subscriptions.

Finder: Used for syncing and backing up your iPhone or iPad. 2. Official Downloads for Older Macs

If you are using an older version of macOS (High Sierra or earlier) and need the software:

macOS 10.13 High Sierra: The latest supported version is 12.8.3. macOS 10.14 Mojave: The latest supported version is 12.9.5.

Apple Silicon Macs: iTunes cannot be installed on Macs with M1, M2, or M3 chips as they run newer macOS versions natively. 3. How to "Fix" or Update If you are seeing an error or a "fixed" version prompt:

Background iTunes historically provided music, device syncing, and media library management for macOS and Windows. Apple has, over recent macOS releases, split iTunes functionality into separate apps (Music, TV, Podcasts) and incorporated device management into Finder.
