Update to iOS 17.7 with Mac

[FridgeToaster]

In a few days iOS 18 will be released and it probably will be the only downloadable iOS when the iPhone is connected to Mac. If I want to update to 17.7 it seems that the only way is OTA update. I was wondering if I can download iOS 17.7 from the apple developer site (Here) and update with downloaded IPSW file? Has anyone tried this before?

You can always download IPSW but they will only be usable when signed by Apple...

IPSW links from the website point to Apple servers

And can get direct links to Apple servers/downloads at ipsw.me

This. So good for a couple of weeks, maybe: 16.6.1 was unsigned on or about Oct 3, 2023 after 17 was released, 17.6 had a shelf-life of only a week after 17.6.1 release (but since that's a point release, two weeks would be a safe bet imo).
