So use your cellular data to update the iPhone if you have an issue.
Unplug from the Mac, turn off Wifi
iPhone>Settings>General>Software Update> "Download and Install" >>Use Cellular Data — YES
If you want a current backup manually do that first...

"Why cant I update iPhone 15 pro as usual with cable via finder & MPB ?: interesting - I cant update iPad via cable either.... I hope they didnt get rid of updating via cable."

Turn Off All VPNs. Are you using a VPN on the iPhone? If so, turn it off.
Well, I cant edit title of this topic now.... So it seems that the information Apple Support gave me re: having to update MBP to iOS 26 to be able to update other devices via cable via MBP was WRONG. I just updated MBP to iOS 26 then tried to update iPad Pro to iOS 26 via cable via finder and got this message:
So no cable update anymore it seems.
So you DID update to MacOS 26 now?
what model-year MacBook Pro?
if you inspect on your iPhone:
settings > general >software update ,,,
... does it also say 18 is the latest?
have you Tried Restarting your iPhone?

Updating Through Use of a Computer:
Though you've already tried it, see if either if my User Tips lead the way. Connecting your Mac to Ethernet, you might not get this error. Use this for a USB-C only Mac: Belkin USB-C to 2.5Gb Ethernet Adapter - Apple
My User Tips:
I updated iPhone wirelessly as iOS 26 was not being detected via cable in finder. MBP M3 Max, 2023 - now on Tahoe 26.1. My iPad Pro is last device still on 18.7.2, iPad Pro 3rd gen, 11 inch. Still not able to do that one for some reason with cable - iOS 26 not being detected. See here: IOS not being detected. I stated it when I discovered it was an iOS detection issue.
I know I can update the iPad wirelessly. BUT, trying to determine whats stopping the update from being detected via cable....
I have no problem with updates via USB cable.
The feature has not been eliminated. It must be something about your setup.
"this model mbp does not have a cat5 port. I have to use some type of adapter , hence the dongle."
-------
Getting CAT5 Cable:
"Dongle" or "Adapter", call it want you want to; nonetheless, it is what to use, if you want to proceed with Ethernet. Which type to get depends on the port of your Mac: USB-A or USB-C
Yep. Got that. Just though it was weird that I can do it from mbp - especially - since most phones auto update anyway. Never was not able to update via Mac before iOS 26.
interesting - I cant update iPad via cable either.... I hope they didnt get rid of updating via cable.
Well I haven’t changed anything. Tried 2 different cables and 3 different ports on Apple display and mbp. I can sync and backup but finder says no updates available. See screenshots above.
I tried via cat5 and hyperdrive dongle which works fine for syncing, moving files etc. I have no vpn enabled.
so apple removed the other thread. Still an issue - they removed the more correct issue..... iOS not been detected.
Yes, I tried Ethernet. I get same message - iOS 18 is latest. iOS 26 is not being detected.

Ethernet:
I'm not referring to a crossover cable --I'm referring to a strait-through cable: Connect your Mac to the Internet using Ethernet - Apple Support
Why cant I update iPhone 15 pro as usual with cable via finder & MPB ?
