Updating iOS16.6 to iOS 27 thru Macbook. The software for the iPhone “iPhone ” was corrupted during download.

I'm trying to update my iPhone 11Pro (iOS 16.6) thru my Macbook (Golden Gate), but I keep on encountering the error "The software for the iPhone “iPhone ” was corrupted during download.". I can't update on my phone directly as I only have 64gb of storage and I'm using 60.5gb currently.


How do I fix this?


Thanks.

Hi there


Try this


Your Mac has saved a broken copy of the iOS update file (called an .ipsw file). Until you delete it, your Mac will keep trying to use it.


  1. Disconnect your iPhone from your Mac.
  2. Open Finder on your Mac.
  3. Click Go in the top menu bar, hold down the Option (⌥) key, and click Library (this folder is hidden unless you hold Option).
  4. Navigate to: iTunes > iPhone Software Updates (Note: Even on newer macOS versions like "Golden Gate", Finder still uses this folder path).
  5. Delete any files you see inside this folder (they will end in .ipsw).
  6. Restart your Mac, reconnect your iPhone, and try the update again.
