Over time, your Mac can accumulate multiple iPhone backups that take up significant disk space. Learning how to delete iPhone backup on Mac helps you reclaim storage and keep your backup list organized.
This guide walks you through the main locations where backups are stored and the steps to safely remove old or unwanted backups. Follow these actions carefully to avoid deleting backups you still need.
| Backup Type | Storage Location | When It Is Created | How to Identify |
|---|---|---|---|
| iTunes Backup | Mac ~/Library/Application Support/MobileSync/Backup/ | During iTunes sync | Long hash string folder name |
| iCloud Backup | Apple iCloud servers | When device is charging and on Wi‑Fi | Managed via iCloud settings |
| Xcode Device Backup | DerivedData and device-specific folders | During debugging or device snapshot | Linked to Xcode project or device UDID |
| Encrypted Local Backup | Same Backup folder with encryption flag | When you set a backup password in iTunes | Requires password to restore |
Locate iPhone Backup on Mac
Finding where backups are stored is the first step before deletion. macOS hides system library folders by default, so you need to reveal them to access the backup directories.
Open Finder, press Command+Shift+G, and enter the path to the backup folder. For iTunes backups, navigate to ~/Library/Application Support/MobileSync/Backup/. Each subfolder corresponds to a specific device and is named by a hash string.
For Xcode-related backups, check DerivedData located in ~/Library/Developer/Xcode/DerivedData/. These folders appear when you build or run an app on a physical device from Xcode.
Identify Old or Unwanted Backups
Review Backup Sizes and Dates
Backups can grow large, especially with photos and app data. Sort the backup folder by size or date to quickly spot candidates for removal.
Compare the folder timestamps with your devices to determine whether a backup is still relevant. If a backup predates a recent full sync, it is likely safe to remove.
Check Backup Integrity
Before deleting, verify that your current device state is covered by a more recent backup. This prevents accidental data loss if you need to restore later.
Delete iPhone Backup on Mac Safely
Once you identify the backup to remove, you can delete the entire folder associated with a specific device. There is no need to manually pick individual files.
Move the target folder to the Trash and then empty the Trash to fully reclaim storage. Immediately emptying the Trash ensures the disk space is freed.
If the backup is encrypted and you no longer need it, deletion follows the same process. Confirm the encryption status in iTunes preferences if you are unsure about a specific folder.
Manage Future Backup Storage
Regular maintenance prevents accumulation of obsolete backups. Set a schedule to review your backup folder every few weeks.
Consider turning on iCloud Backup to offload older local backups to Apple servers. This reduces reliance on local storage while keeping your data recoverable.
Best Practices for Backup Management
- Periodically review the Backup folder to identify large or outdated entries.
- Keep at least one recent local backup if you frequently work offline.
- Use iCloud Backup for daily protection and delete older local copies.
- Empty the Trash promptly after deleting backups to free disk space.
- Document the device name and date when you create manual notes about a backup.
FAQ
Reader questions
Will deleting a local iPhone backup remove data from my device? No, deleting a local backup on your Mac only removes the copy stored on your computer. Your device retains its current data unless you erase it intentionally. Can I delete specific files inside a backup folder instead of the whole folder?
Do not delete individual files inside a backup folder, as this can corrupt the entire backup. Remove the entire folder if you want to discard that backup.
How do I know which backup belongs to which device or date?
Folder names are hash strings, but you can map them by checking their creation date and size in Finder. iTunes also shows the sync timestamp in the device summary if connected. No, local backups on your Mac are separate from iCloud storage. Deleting them does not change your Apple ID or iCloud plan in any way.
