Is It Safe to Delete iOS Software Update Files on Mac?

What are iOS Software Update files?

When you plug your iPhone or iPad into your Mac to perform a system update or restore it via Finder (or iTunes on older Macs), your computer downloads the massive iOS operating system installer-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder) file (.ipsw) directly to your hard drive.

Why Do They Exist?

Your Mac downloads these files so it can push the fresh operating system onto your mobile device via the USB cable. Because iOS is a complex, modern operating system, these files are enormous—frequently taking up 5GB to 8GB of space for a single device.

Can You Delete Them?

Yes, it is 100% safe to delete them.

Once your iPhone or iPad has successfully finished updating or restoring, the installer file serves absolutely no purpose. macOS is supposed to clean these up automatically, but it often fails to do so, leaving massive “iOS Files” taking up permanent residence in your Mac’s Storage settings.

How to Delete Them

The Easy Way (macOS Storage Manager):

1. Click the Apple Logo in the top left > System Settings (or System Preferences).
2. Click General > Storage.
3. Look for iOS Files in the list and click the “i” info button next to it.
4. Select the old updates and click Delete.

The Manual Way (Finder):

1. Open Finder and press Cmd + Shift + G.
2. Type ~/Library/iTunes/iPhone Software Updates and press Enter.
3. Drag any .ipsw files you see in this folder to the Trash.
4. Empty the Trash.

What Happens If You Delete It?

You will instantly reclaim a massive amount of storage space (often 10GB+ if you have updated multiple devices over the years). It will not affect your iPhone, your backups, or your Mac’s functionality in any way. The next time you try to update your phone via your Mac, it will simply download the newest file again.

Bottom Line

Deleting leftover iOS Software Update .ipsw files is one of the easiest, safest, and most effective ways to free up massive amounts of storage on a full Mac.
