How to Delete Old iPhone Backups on Mac in 2026 (Finder + Manual, Step-by-Step)

If you have ever wondered how to delete old iPhone backups on Mac, you are not alone. Local device backups created through Finder (or the old iTunes) accumulate silently over months and years, and a single full backup can consume anywhere from 4 GB to 30 GB of your internal storage. In 2026, with macOS Sequoia and the forthcoming Tahoe release, the process is straightforward — but the exact steps differ depending on whether you use Finder's built-in manager, navigate the folder manually, or reach for Terminal. This guide covers all three approaches so you can choose whatever fits your workflow.

Where Does macOS Store iPhone Backups?

Since macOS Catalina replaced iTunes with Finder, local iPhone and iPad backups live in the same place they always have — a hidden library folder inside your home directory:

~/Library/Application Support/MobileSync/Backup/

Each backup is stored as a folder named with a long hexadecimal device identifier (e.g., a1b2c3d4e5f6...). Inside you will find thousands of small files organized into subdirectories — macOS does not store them as a tidy .zip you can simply drag to the trash. The folder for a single device can contain 50,000 or more files, which is why macOS provides a dedicated manager rather than expecting you to delete folders by hand.

How Much Space Are Your Backups Actually Using?

Before you delete anything, it is worth understanding the typical size range. The table below gives a rough breakdown based on device and backup age in 2025–2026.

If you have upgraded devices even once in the last three years, you almost certainly have at least one orphaned backup taking up tens of gigabytes. See our overview of what is taking up space on your Mac for a fuller picture of where storage goes.

Method 1: Delete iPhone Backups Through Finder (Recommended)

This is the safest and most straightforward method. Finder lets you see every local backup by name, device model, and last-modified date before you delete anything.

1. Connect your iPhone to your Mac with a USB cable, or open Finder without a device connected — either works for managing existing backups.
2. In the Finder sidebar, click your iPhone under Locations. If your device is not currently connected, open Finder and go to Finder > Preferences > Sidebar to make sure CDs, DVDs, and iOS Devices is checked — then connect and click it.
3. In the device pane, click the General tab (it opens by default).
4. In the Backups section, click Manage Backups…. A sheet drops down listing every local backup on your Mac, including backups for devices you no longer own.
5. Select any backup you want to remove. You can hold Command to select multiple entries.
6. Click Delete Backup, then confirm when prompted. Finder handles the entire folder removal — you do not need to touch the file system.

Tip: Sort the list by Last Modified to identify stale backups from devices you have already replaced or sold. Those are always safe to delete.

Method 2: Delete Backups Manually in Finder (Go to Folder)

If you want to inspect the raw backup folders — for example, to check sizes individually in column view — you can navigate there directly:

1. In Finder, press ShiftCommandG to open the Go to Folder sheet.
2. Type the following path and press Return:
   ~/Library/Application Support/MobileSync/Backup
3. Switch Finder to column view (Command3) so you can see each folder's size in the preview column.
4. Select the device folder you want to remove and press CommandDelete to move it to the Trash, then empty the Trash.

Because backup folders can contain tens of thousands of tiny files, emptying the Trash may take a few minutes. This is normal. Do not force-quit Finder mid-deletion.

Method 3: Delete iPhone Backups Using Terminal

Power users or those managing Macs remotely via SSH can remove backups from Terminal. First, list what is there:

ls -lh ~/Library/Application\ Support/MobileSync/Backup/

Each line shows a folder named by device UDID. To check the total size of one backup:

du -sh ~/Library/Application\ Support/MobileSync/Backup/a1b2c3d4e5f6abcdef1234567890abcdef123456

Replace the long hex string with your actual folder name. To delete it:

rm -rf ~/Library/Application\ Support/MobileSync/Backup/a1b2c3d4e5f6abcdef1234567890abcdef123456

The rm -rf command is permanent and bypasses the Trash, so double-check the folder name before pressing Return. Prefer the Finder method if you are not comfortable with Terminal.

Is It Safe to Delete Old iPhone Backups?

Yes — with one important caveat. Deleting a backup removes your only local restore point for that snapshot in time. Before you delete:

• Make sure iCloud Backup is on (Settings > [Your Name] > iCloud > iCloud Backup) if you want a cloud copy going forward.
• Keep the most recent backup for any device you still own and actively use, especially before a major iOS update or device trade-in.
• Backups for sold or lost devices contain no data you can access anyway — delete those freely.
• Deleting a backup does not affect the data on your iPhone itself. Your photos, contacts, and apps remain on the device; you are only removing the local archive copy on your Mac.

How to Prevent Backup Bloat Going Forward

Backups grow because they include app data, offline content, and cached media from your device. A few habits keep them manageable:

• Exclude large apps from backup. On your iPhone, go to Settings > [Your Name] > iCloud > Manage Account Storage > Backups, select your device, and toggle off apps with large footprints (streaming apps, games, podcast caches).
• Back up to iCloud instead of locally if your Mac's internal SSD is tight. iCloud Backup handles incremental snapshots and is automatically pruned.
• Schedule a quarterly review. Open Finder, click Manage Backups, and delete anything older than three months or belonging to a device you no longer own.
• Watch your whole Library folder. iPhone backups are often only part of the story — freeing up space on Mac usually means auditing several folders at once, including ~/Library/Caches, ~/Library/Developer, and ~/Downloads. A tool like Crumb can audit all of these at once and show what is safe to delete before you remove anything.

Troubleshooting: Backup Won't Delete or Finder Shows No Backups

Finder shows no backups in Manage Backups

This usually means all your backups are stored in iCloud, not locally. Open System Settings > [Your Name] > iCloud > Manage Account Storage > Backups to see and delete cloud backups instead.

The Trash won't empty after manual deletion

Large backup folders sometimes trigger macOS's extended Trash confirmation. Try emptying via Terminal:

sudo rm -rf ~/.Trash/*

Enter your administrator password when prompted. This empties all items currently in your Trash.

Backup folder is locked or permission-denied

Run a Quick Look on the folder — if it shows a lock icon, repair permissions from Terminal:

chmod -R u+rwX ~/Library/Application\ Support/MobileSync/Backup/

Then retry deletion through Finder.

Summary

iPhone backups on Mac pile up quietly, and a single outdated backup from a device you sold two years ago can claim 20 GB or more. The fastest path is Finder's built-in Manage Backups sheet — it is safe, shows you what you are deleting, and handles the thousands of internal files automatically. For bulk cleanup or remote management, the rm -rf Terminal route works just as well. Either way, confirm you have an iCloud or a current local backup for devices you still rely on before you delete, and you will reclaim that space without any risk to your actual iPhone data.
