Reboot both, make sure iTunes is patched to current, and try again.

If that fails, boot the Mac into Safe Mode, and try again from there. This temporarily disables add-ons, and rebuilds caches.

Here’s the general sequence: If you see an error in iTunes on your Mac or PC - Apple Support

One other suggestion is de-authorizing and re-authorizing the computer.

I’d also log into AppleID.Apple.Com and check the payment info, and whether there’s a new agreement to agree to.

If not that... Ring up Apple Support, then. There’s not much around on that error code.

This Answer solved my problem:

1. Ensure that you install all updates on your iPhone.

2. Download and install (again!) the latest version of iTunes from

<https://www.apple.com/uk/itunes/>

3. In the Finder, use the menu command Go to Folder in the Go menu to

open the folder (copy and paste this into the dialog)

/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/Current/Resources

4. Unlock your iPhone and connect it to your Mac.

5. In that open folder, double-click the item MobileDeviceUpdater, and

it should inform you of a software update. Install that, and iTunes

should then recognise your device.

Some users find that they don't need to do step 5, as macOS does that

automatically.

I wish you success,

Very best regards,

Howard.

Thank you, I did both suggestions, still get that error code. I would upgrade from High Sierra but my current MacBook Pro is at the end of the line for system software. Thank you for the advice, most appreciated.
