What is the max version?
The maximum supported OS is the highest version of iOS, iPadOS, macOS, tvOS, or watchOS that Apple ever released for a given device — regardless of current signing status.
Signing vs Max version
Even if the max version is no longer signed by Apple, it still runs fine if already installed. Signing only matters when restoring or updating for the first time.
Always fresh data
This tool fetches data live from the IPSW Downloads API on every lookup — no caching — so you always see the latest firmware releases the moment Apple issues them.
