How to Transfer Custom Ringtones from macOS Catalina to iPhone

This guide walks you through moving custom ringtones from a Mac running macOS Catalina to an iPhone using Finder and the Music app. You’ll need the ringtone file in M4R format, a USB cable, and both devices signed into the same Apple ID.

What You’ll Need

• Mac running macOS Catalina (10.15) or later
• iPhone with a recent iOS version
• USB cable (Lightning or USB-C, depending on your iPhone)
• Ringtones in M4R format (you can convert AAC files to M4R using iTunes or a converter)
• Latest version of iTunes (for the Music app) or Finder

Step-by-Step

1. Prepare your ringtone files. Ensure each ringtone is an M4R file (the iPhone ringtone format). If you have M4A files, rename the extension from .m4a to .m4r (on a Mac, right-click the file, select Get Info, and change the extension in the Name & Extension field).
2. Connect your iPhone to your Mac. Use a USB cable and plug the iPhone into the Mac. If prompted on the iPhone, tap Trust and enter your passcode.
3. Open Finder. In the Finder sidebar, under Locations, click your iPhone’s name. If this is the first time, click Trust on the Mac as well.
4. Enable manual ringtone management (if needed). In the Finder window, click General at the top. Scroll to Options and check Manually manage music, videos, and podcasts. This isn’t required for ringtones, but it avoids conflicts. Click Apply if you changed anything.
5. Go to the Tones tab. In the Finder window, click the Tones tab (you may need to scroll down in the sidebar). If you don’t see it, make sure your iPhone is unlocked and you’ve trusted the computer.
6. Add ringtones. Drag and drop the M4R files from a Finder window into the Tones section. Alternatively, click Add (the plus icon) and navigate to the files.
7. Sync. After adding the tones, click Sync in the bottom-right corner of the Finder window. Wait for the sync to finish. Do not unplug the iPhone during this time.
8. Verify on iPhone. After syncing, disconnect the iPhone. Go to Settings > Sounds & Haptics > Ringtone. Your custom tones should appear in the list under Custom.

Common Mistakes

• Wrong file format: Ringtones must be M4R, not M4A or MP3. If you add an MP3, it won’t appear as a ringtone.
• Forgetting to trust the computer: If you skip the Trust prompt, Finder won’t see the iPhone.
• Not unlocking the iPhone: The iPhone must be unlocked during sync or Finder may not detect it.
• Dragging into the wrong place: Make sure you drag files into the Tones tab, not the Music tab.
• Using iCloud Music Library: If you have iCloud Music Library enabled, it can interfere with manual syncing. Turn it off temporarily in Settings > Music on the iPhone.

Tips

• Keep ringtones under 30 seconds: The iPhone allows ringtones up to 30 seconds; longer files may be rejected.
• Use the same Apple ID: Ensure both devices are signed into the same Apple ID to avoid sync issues.
• Backup your ringtones: Keep a folder on your Mac with all M4R files so you can re-add them after a restore.
• Use Finder’s search: If you have many files, use the search bar in the Tones tab to find specific ringtones.
• Convert from GarageBand: You can create custom tones in GarageBand and export them as M4R files directly to your Mac.

Troubleshooting

• iPhone not showing in Finder: Try a different USB port, restart both devices, and ensure you’ve clicked Trust on both screens. Also check that the iPhone is unlocked.
• Ringtones don’t appear on iPhone: Re-check the file format (must be M4R). Also, verify you dragged them into the Tones tab, not Music. Try re-syncing after removing and re-adding the files.
• Sync fails or hangs: Disconnect and reconnect the iPhone, then try again. If the issue persists, restart the Mac and iPhone.
• Files greyed out: This usually means the file is not a valid M4R. Re-export or convert the file properly.
• iCloud Music Library conflict: Go to Settings > Music on the iPhone and toggle off Sync Library. Then re-sync via Finder.
• Finder says the iPhone is in use: Close any other apps that might be accessing the iPhone (like Photos) and try again.

Frequently Asked Questions

Can I transfer ringtones wirelessly?

No, macOS Catalina and later do not support wireless syncing for ringtones. You must use a USB cable.

What if my ringtone is longer than 30 seconds?

The iPhone will automatically trim it to 30 seconds, or it may reject it. It’s best to edit the file to under 30 seconds before transferring.

Do I need to convert MP3 to M4R?

Yes, the iPhone only accepts M4R format for ringtones. You can convert MP3 to M4R using iTunes (File > Convert > Create AAC Version) and then rename the extension.

Why don’t I see the Tones tab in Finder?

Make sure your iPhone is connected and trusted. If it still doesn’t appear, go to Finder > Preferences > Sidebar and check CDs, DVDs, and iOS Devices.

Can I use the same ringtone for text tones?

Yes, once synced, you can assign the same tone to text messages under Settings > Sounds & Haptics > Text Tone.

Will syncing erase my existing ringtones?

No, syncing adds the new tones without removing existing ones, unless you uncheck the ones you want to remove in the Tones tab.
