Installed iOS 12, won’t connect to Mac.

[Rob]

Ok so I’m going to need a proper apple geek here....

Got my new iPhone XS, in order to backup and sync I had to update the OS on my MacBook as I was running Yosemite and iOS 12 doesn’t sync with an OS that old.

Anyway, so I do the OS update and now the iPhones are totally unresponsive. Like 100%, it still charges the phones (both old and new). Any ideas taken.

When I was on the older iOS it at least told me that it couldn’t sync. Now it does nothing. Fark

A pop up should appear when you plug the phone in saying something along the lines of you need to download this update to connect your iPhone. When I first saw it pop up I thought it was some spam, it’s not very Apple-like in form.

Check in iTunes that you’ve authorised that device (allowed your computer access to it)

I think I've had this problem before.

Update iTunes on the new OS. Plug in your old phone and back it up again and then try to restore to new device with the new back up from the new iTunes.

I think you're trying to restore an old system on the new system If that makes sense.
