The iTunes 10.13.99 Requirement
You may encounter an error stating that a specific iTunes installer "requires macOS version 10.13.99 or earlier". This typically happens because:
OS Incompatibility: Modern macOS versions (Catalina, Big Sur, Monterey, and later) do not natively support standalone iTunes installers.
Feature Split: Apple has integrated iTunes features directly into Finder (for device syncing) and the Music app. How to Install iTunes on New macOS Versions
If you must use iTunes on a newer Mac, you cannot simply download a standard .dmg from Apple. You will need a workaround like Retroactive.
Download Retroactive: Find this tool on its official GitHub page.
Bypass Security Blocks: Since it is from an unidentified developer, you may need to go to System Preferences > Security & Privacy and click "Open Anyway" to run it.
Select iTunes Version: Choose the specific version you need (e.g., iTunes 12.9.5 or 12.6.5 for App Store support) within the Retroactive interface.
Authenticate and Install: Follow the prompts to download and configure the app. You will need to grant Full Disk Access in your system settings for it to function correctly. Official Legacy Downloads
