Why is sync library not an option on my iPhone?

There are a few potential reasons why you may not see the sync library option on your iPhone:

First, make sure you have the latest version of iTunes installed on your computer. The sync library option requires iTunes 12.5 or later. Go to iTunes > Check for Updates to download the newest version.

Second, check that you have enabled iTunes Match on your iPhone. Sync library is only available for devices with an Apple Music subscription or iTunes Match enabled. Go to Settings > Music and make sure “Show Apple Music” is toggled on.

Third, if you use Family Sharing, you may need to ensure you are logged into the correct Apple ID that is enabled for syncing. Go to Settings > iTunes & App Store and check you are signed into the proper account.

What is the Sync Library option on iPhone?

The sync library option allows you to access your entire Apple Music or iTunes Match library from your iPhone, without needing to manually sync specific songs or downloads to the device.

When sync library is enabled, your full song library is available to stream or download on your iPhone, similar to how Spotify or other streaming services work. This gives you access to your music collection anywhere with a data or WiFi connection.

Benefits of using Sync Library

  • Music is available even without a local download, as long as you have an internet connection

Why isn’t Sync Library showing up for me?

If you are not seeing the Sync Library option on your iPhone, here are some potential reasons why:

Software is out of date

Make sure your iPhone is updated to iOS 13.4 or later, which is required for Sync Library. Also confirm your computer has the newest version of iTunes (12.5+).

You don’t have an active subscription

Sync Library requires an Apple Music subscription or iTunes Match. Check in Settings > Music that you are subscribed and signed into the proper Apple ID.

iPhone and computer are not on the same WiFi

Initially enabling Sync Library requires your devices to be on the same local network. Make sure WiFi is on for both devices and connected to the same network.

Family Sharing is enabled

If using Family Sharing, the syncing settings may be disabled. Ensure you are logged into the Family Organizer’s account on your iPhone.

Restrictions are blocking access

Check in Settings > Screen Time > Content & Privacy Restrictions to see if Apple Music is disabled. Sync Library requires full access to Apple Music.

There’s a connection issue

Poor internet connection, VPN usage, firewalls, or other network issues can prevent Sync Library from working properly. Try resetting Network Settings on the iPhone.

Corrupt local files

Extremely corrupted or invalid files in your local iTunes library can sometimes prevent Sync Library from completing setup. Deleting problematic songs may help.

Insufficient iCloud storage space

There needs to be enough available space in iCloud to upload any music not already in Apple’s catalog. Check iCloud storage levels under Settings > Your Name > iCloud.

How to troubleshoot when Sync Library is not working

If you have Sync Library enabled but it is not functioning properly, try these tips:

  1. Check for iOS and iTunes app updates
  2. Sign out then back into iCloud and iTunes & App Store
  3. Toggle Sync Library off/on under Settings > Music
  4. Restart your iPhone and computer
  5. Check Apple system status page for any known outages
  6. Toggle WiFi off/on to reconnect
  7. Reset Network Settings on the iPhone

In most cases, upgrading software, signing out/in, toggling Sync Library off and on, and restarting devices will resolve any syncing issues. For continued problems, reach out to Apple Support for further troubleshooting assistance.

Alternative options if Sync Library is not working

If Sync Library is simply not functioning despite troubleshooting, here are some alternative options:

Manual Music Sync

You can manually transfer music from computer to iPhone using a wired connection in iTunes. This is more time-consuming but will get songs onto your device.

Apple Music Downloads

Although you can’t access your full library, the Apple Music app lets you download any songs, albums or playlists for offline playback.

Third Party Apps

Apps like Documents by Readdle allow you to transfer audio files from computer to iPhone over WiFi using a web browser. This works for songs not purchased through Apple.

Bluetooth File Transfer

You can send individual audio files from your computer to iPhone using Bluetooth. Just pair the devices then send music across.

Offline Music Playback

If none of the above options work, you can play music stored directly on the device using the Music app in offline mode, with no internet connection required.

Why is Sync Library using so much iPhone storage?

There are a couple reasons why Sync Library may take up significant storage space on your iPhone:

  • Downloading songs for offline playback – Music you choose to download will be stored locally and take up storage. Delete downloads to free up space.
  • Uploading your library – Songs that get uploaded to iCloud will be temporarily cached on your iPhone, using storage. Completed uploads get removed.
  • Ineligible songs – Tracks uploaded as full files because they didn’t match Apple’s catalog also consume more space.

You can check how much space Sync Library is using under Settings > General > iPhone Storage. Tap Music to see the breakdown between downloads, caches, and uploads.

Some tips to reduce Sync Library storage usage:

  • Turn on Optimize iPhone Storage to only keep downloads for recent music.
  • Delete old downloads manually that you don’t listen to regularly.
  • Wait for pending uploads to finish, which will remove the caches.
  • Disable Sync Library and use manual music syncing instead.

Why uploaded tracks use more storage

Music files uploaded in their original format because they didn’t match Apple’s catalog can take up a lot of space compared to Apple Music’s DRM versions. If you have a lot of eligible uploads, consider enabling iTunes Match for $24.99/year which will match and replace most songs to save storage.

Best practices when using Sync Library

To ensure Sync Library works smoothly and efficiently, follow these best practices:

  • Update to the latest iOS and iTunes versions
  • Use iCloud Music Library only on trusted home & personal networks
  • Connect iPhone and computer to power before starting initial sync
  • Delete old downloads to optimize iPhone storage
  • Wait for pending uploads to complete before syncing again
  • Limit extreme metadata editing that could corrupt local files
  • Toggle Sync Library off/on to reset when troubleshooting issues
  • Report significant problems to Apple via appleid.apple.com

Following these tips will help avoid common problems and keep your music library seamlessly up to date across all devices!

Frequently Asked Questions

Is Sync Library the same as iTunes Match?

Sync Library and iTunes Match work together but are not exactly the same. iTunes Match is a paid add-on ($24.99/year) that uploads your library for access across devices like Sync Library. But Sync Library is included with Apple Music, while Match must be purchased separately.

Do all my songs get uploaded to iCloud?

Only songs that aren’t already in Apple’s catalog will upload. Anything matched to Apple Music will sync without uploading. iTunes Match can match even more tracks to minimize uploads.

Can I redownload deleted music?

Yes, any music you’ve added, whether uploaded or Apple Music tracks, can be redownloaded from the cloud even if deleted locally.

Do playlists get synced?

Yes, any playlists you’ve created in your library will automatically sync across devices when using Sync Library.

What song limit is there?

There is no explicit limit to the number of songs your library can have. However, storage constraints may apply if you have over 100,000 local tracks to upload.

What devices support Sync Library?

Sync Library works on iPhones, iPads, iPod touches, Macs, PCs, and Apple TVs. It requires iOS 13.4, macOS Catalina, iTunes 12.5 or later, or tvOS 13.4 or later.

Can I merge libraries from multiple computers?

Unfortunately Sync Library does not allow merging or combining music libraries from multiple sources. It will sync the library on the first connected computer only.


In summary, Sync Library provides a convenient way to access your full Apple Music or iTunes Match collection across your devices. Make sure software is up to date, subscriptions are active, devices are connected to the same WiFi, and there is enough iCloud storage space available. Follow best practices and troubleshoot issues as needed. With some patience, Sync Library should successfully match your music library everywhere!
