Error 13014 is a music-synchronization failure. It usually appears while iTunes, Music, Finder, Apple Music, or Apple Devices is copying songs to an iPhone, iPad, or iPod. Apple does not assign one definitive cause to the code, so the safest fix is a non-destructive sequence: update both devices, back up the library, consolidate accessible media, test security software, then isolate and replace any track that causes the sync to fail.
What error 13014 means
Apple groups 13014 with music-sync errors -5000, -69, and 13010. The message does not prove that an iPhone is damaged or that the library database is corrupt. In practice, the sync process cannot successfully read, access, or transfer one or more library items. Apple identifies dispersed media files, third-party security software, and individual songs as possible causes: Apple’s troubleshooting guidance.
First identify your setup. iTunes handles syncing on macOS Mojave or earlier; Music manages the library and Finder handles device syncing on macOS Catalina and later. On current Windows installations, Apple Music and Apple Devices are the preferred apps, although iTunes for Windows remains available for compatible PCs and certain legacy uses. See Apple’s Windows app guidance.
Quick, non-destructive checklist
- Update macOS or Windows and the iPhone, iPad, or iPod.
- Back up the library database and the actual media files.
- Consolidate accessible media into one library location.
- Check external drives, network folders, moved files, and unavailable tracks.
- Temporarily test third-party security software, then immediately re-enable it.
- Sync small groups of songs to identify a failing track.
- Redownload a failed purchase or re-import a CD-rip or other imported file.
Before changing the library: make a backup
Copy the library database and media files to a separate backup location, including any external drive that stores music. Consolidation creates copies in the central media folder; it does not automatically delete the originals, according to Apple’s iTunes documentation. Do not treat Apple Music Sync Library as a backup service; Apple explicitly says it is not one: Sync Library requirements and limitations.

1. Update and restart everything
Install available updates for the computer and the Apple device. On Mojave or earlier, install the newest iTunes version available for that macOS release. On Windows, update Apple Music, Apple Devices, or iTunes through the Microsoft Store as applicable. Restart the computer and device, reconnect with a reliable cable, and retry before making more invasive changes. Apple specifically recommends updating both sides before investigating these sync errors: Apple Support.
2. Consolidate the music library
macOS Mojave or earlier with iTunes
- Open iTunes.
- Choose File > Library > Organize Library.
- Select Consolidate files.
- Optionally select Reorganize files in the folder “iTunes Media”.
- Start the operation, wait for it to finish, and retry the sync.
Apple says consolidation places accessible media in one location and can simplify syncing and correct certain access problems. It copies files into the iTunes folder while leaving originals in place. It cannot recreate files that have already been deleted or moved somewhere unavailable. Avoid manually moving the iTunes folder or its internal folders, which can create broken library paths; see Apple’s consolidation documentation.
macOS Catalina or later with Music and Finder
Music stores the library and Finder performs device synchronization. Use the Music app’s library-organization or consolidation command available in your macOS version, then connect the device and manage syncing in Finder. Labels vary by macOS release, so do not apply the old iTunes menu path literally.
Rank #2
3. Find unavailable or misplaced files
Check whether music is on a disconnected or locked external drive, network share, removable disk, renamed folder, or cloud folder whose files are not downloaded locally. In iTunes, select a track and use File > [Item] Info to inspect its location or File > Show in Finder to locate it. A song listed in the library without a readable source must be restored, reconnected, or re-imported before it can sync.
| Symptom | Best investigation |
|---|---|
| Nearly every song fails | Update software, consolidate the library, check security software and library-drive access, then retry the current Finder or Apple Devices workflow. |
| One album or playlist fails | Test its tracks in small groups and repair the offending file. |
| The error began after moving the library | Reconnect the original storage and inspect file paths before reorganizing. |
| A purchased track fails | Confirm the purchase remains available and redownload it. |
| A CD-ripped or other imported track fails | Re-import it from the original disc or source files. |
4. Test third-party security software
Antivirus, endpoint-security, firewall, VPN, file-monitoring, or cleaner software can interfere with synchronization. Check its quarantine and blocked-app history for iTunes, Music, Finder, Apple Devices, or the media folders.
- Pause protection temporarily only if the product supports a controlled test.
- Retry the sync with the same songs.
- Turn protection back on immediately.
- If the error disappears, create a narrowly scoped, vendor-supported exception or contact the security vendor.
Do not permanently disable antivirus or firewall protection, and do not assume security software is responsible without this comparison.

5. Isolate the song that breaks synchronization
Apple recommends syncing a few songs and adding more until the error returns: official troubleshooting steps. A faster binary-search method is useful when the library is large:
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- Try a small, known-good playlist.
- Add a batch, such as 100 songs.
- If it fails, test half the batch, then half of the failing half.
- Continue dividing until one track or a small set consistently triggers 13014.
If every small test fails, return to software, storage, security, and device-workflow checks rather than deleting the whole library.
6. Redownload or re-import the offending track
iTunes Store purchase
Verify that the item is still available to the Apple Account, preserve your backup, then remove only the problematic local copy and redownload it from purchase history. Availability can vary by country or region, or if the item is no longer offered. Instructions are in Apple’s previous-purchases guide.

7. Use the correct synchronization workflow
Current Mac: Music plus Finder
- Connect the device and open Finder.
- Select the device in the sidebar and choose Music.
- Enable music synchronization.
- Choose the entire library or selected artists, albums, genres, and playlists.
- Click Apply or Sync.
Apple’s current Finder procedure is described at Sync music between your Mac and device.
Current Windows: Apple Music plus Apple Devices
- Install Apple Music and Apple Devices from the Microsoft Store.
- Open Apple Devices and connect the iPhone, iPad, or iPod.
- Select the device, choose Music, and enable Sync music onto [device name].
- Choose all music or selected categories and click Apply.
Apple Music must be installed for music synchronization through Apple Devices: Apple’s Windows instructions. iTunes for Windows remains an option for PCs that need it; see Apple’s app overview.

Subscription music is not handled like ordinary local files when Sync Library is enabled. Sync Library requires an Apple Music or iTunes Match subscription, and manual USB syncing follows a different workflow. Decide whether you want cloud-based Sync Library or manual syncing; do not mix the two casually. Details are in Apple’s Sync Library documentation.

Warnings about Erase and Sync
An iPhone or iPad can sync with only one Apple Music or Apple TV library at a time. If Finder or Apple Devices says the device was synced with another library, Erase and Sync replaces the selected content type on the device with content from the current library. It is not a general 13014 repair and can remove existing synced music. Back up first and choose it only when replacing that content is intentional: Apple’s syncing guidance.
For iPod classic, iPod nano, and iPod shuffle, Apple says synchronization with a Windows computer is required because these models have no other way to add content: Windows syncing overview.
Quick Recap
If error 13014 still appears
- Test a new playlist containing only a few known-good tracks.
- Confirm every library drive is connected, unlocked, and available before opening the app.
- Try another cable or USB port as a secondary device-connection check.
- Confirm security protection is enabled again and any exception is narrowly scoped.
- Contact Apple Support if a clean, small set of known-good songs still fails after the documented steps.
