Like others, I can't get iTunes 12.8 to detect an iOS 12 device.
I have an older iMac that I specifically upgraded from 10.10 to 10.11 in order to support a recently-upgraded iPod (iOS 12). I've done the whole "unplug device/re-install iTunes 12.8/unlock device/plug-in device" about a thousand times over the past 2 days and I never get prompted to install the additional update. Has anyone else discovered any other workarounds here? I know the iPod works just fine because Photos on the same iMac can detect and import pics and I also tried the iPod on another 10.11 system, which immediately prompted me to install the update - I didn't even have to reinstall iTunes.
On the 10.11 system where it works, in Console, I can see both iTunes and "MobileDeviceUpdater" working together querying the device. The "MobileDeviceUpdater" ultimately says "MobileDevice reports the device needs an update. Asking the user to update." I never see the MobileDeviceUpdater thread on the system that isn't working. The last piece I see is iTunes saying "BootedOS device needs updated MobileDevice.framework; ignoring device." And that's it.
Is "MobileDeviceUpdater" part of iTunes? How does that get broken here?
