iOS 12 iTunes connecting problem

FWIW, iTunes 12.6.4.3 will still sync and allow app management

and downloading with an iPhone 8 running iOS12. It just won't

do anything in terms of iOS updates/upgrades ay least with an iPhone 8.

I have found that if you have the proper .ipsw file phone an iPhone 6S,

you can still manually update/upgrade it.

Ah, have you tried the following yet?

Download the current 12.8 installer for iTunes from https://www.apple.com/itunes/download/.

Unlock your iOS device and connect it to USB.

Install iTunes from the .dmg that you've downloaded.

Near the end of the installation it should announce that a further software update is required.

Install that and iTunes should see your devices.

It might be worth trying what worked for me. turingtest2 posted a link to a page with 12.6.5 available for download. Deploy apps in a business environment with iTunes - Apple Support I installed it without removing any iTunes preference files or anything. It tried to open but couldn't because of one of those files created by my 12.8 iTunes installation. Not a problem, I was trying everything I could think of. I then reinstalled 12.8. Works fine now.

It keeps coming up with additional software required but when attempting to download it it says it's not available on server. I eventually decided to put it into recovery mode and now I have a brick. It just says connect to iTunes but iTunes starts the process , disconnects and gives the error code 9. Can't even use my iPad now.

I tried as you suggested. It never asked me for a further software update.

Still same issue, not able to get my iPhone w/ iOS 12.1 recognized in iTunes 12.8.

And Apple has not made iTunes 12.9 available as a standalone download!

It should work for El Capitan 10.11.4 through High Sierra. iTunes 12.9 is baked into Mojave. There is currently no standalone Mac installer for it.
