I don't know if this has been mentioned before, but if so, I couldn't find it.

Having updated my iPad Pro to iOS 12 this morning, I just plugged it into iTunes to add some videos and found that iTunes no longer recognises the iPad. My late 2014 5K iMac is still running Yosemite, for reasons I won't go into here, and having spent an hour on the phone with Apple, have found there is no way to either go back to iOS 11 or make iTunes on Yosemite compatible. I now have an iPad that I cannot sync or add videos to and a very expensive iPhone Xs Max being delivered Friday that I probably won't even be able to use.

There must be many people running older versions of MacOS and it would have been nice of Apple to warn people that iOS 12 needs at least the iTunes version from El Capitan.

What version of iTunes are you using?
[doublepost=1537297377][/doublepost]I’m on High Sierra using iTunes 12.8.0 and my devices wouldn’t update to iOS12 iTunes. After I updated OTA, iTunes didn’t recognize my devices either. I tried everything and couldn’t get it to work. What fixed it was I deleted iTunes using a terminal command and then re-downloaded a copy from Apple and installed it. After iTunes opened and I plugged my device in a pop up showed stating iTunes needed to download a file to be able to connect to my X. After the file was downloaded, all my devices connected with no issues. It also was listed as 12.8.0 so not sure what was the issue as I checked updates for iTunes the normal way and it said I was fully updated..

Sounds like bad info all around from phone support.

iOS 12 appears to need 12.8 iTunes (all new iOS releases are always "latest version of iTunes" in Apple support pages), but that should be able to run on Yosemite, as long as 10.10.5.

Software:

• OS X version 10.10.5 or later
As BugeyeSTI mentioned, needed to let iTunes download some update/support files (get a popup with a message along the lines of "do not recognize device, need to update software"). After that, all went well.

And should be able to go back to previous iOS:

And: can look into software like AnyTrans, iMazing as iTunes replacements. Yes, they cost money, but have demo versions that can be run to see if would work as iTunes replacement.

How has you iTunes deleted on High Sierra? Can you post the terminal command?

When I went to update my X to 12 - It made me update iTunes. Gave me option to download file etc. Not sure why update didn't appear in the app store.

I'm not sure why people would expect something with the latest software would work and get support on old versions of software. Old software would have drivers, etc. to even recognize new hardware/software.

thanks you will test it once. because with me is since the iOS 12.0 on iPad itunes 12.8 mac version can not recognize it any more.

iOS 11.4.1 no a issue.
Same thing happened to me... Usually iTunes updates come like all other software updates, through the App Store. This file came through the iTunes app when I plugged my X in after updating OTA to iOS12. Supposedly, iTunes 12.9.0 is going to be released next week so I’m sure that will clear things up. I think the files sent out for iTunes yesterday was for the release of iOS12 and compatibility issues with iTunes 12.8.0

I was looking for posts that mentioned AnyTrans to ask if you folks have tried AnyTrans in such ways? Do respond on that thread please. Thanks.
