IPSW Checker

Every Apple firmware, in one app.

Check the IPSW files for any iPhone, iPad, Mac, Apple Watch or Apple TV, betas included. See which versions Apple still signs, and get an alert when that changes.

Requires iOS 17 or iPadOS 17 or later. No ads.

Signed or not, at a glance.

Each firmware lists its build, release date and size, and whether Apple is signing it today. If it says Unsigned, you can skip the 9 GB download.

Open a version to copy or share its link, check the SHA‑256 checksum and read Apple’s release notes.

Hear about it when signing stops.

Follow your Favorites or pick devices one by one. When Apple stops signing a firmware for any of them, your iPhone gets a notification, even if you haven’t opened the app in weeks.

Release alerts for iOS, iPadOS, macOS, watchOS, tvOS and visionOS cost nothing.

Betas right next to releases.

Developer betas, public betas and release candidates show up beside the shipping versions, each with its own IPSW link.

A new beta reaches the app an hour or two after Apple posts it.
