Does iTunes 12.8.0 no longer support older iPods
I just bought a new iMac, all software has been updated, however iTunes no longer recognizes my 2nd Gen iPod touch, or my old iPhone 3G. The message I get when I plug them into the machine is as follows:
iTunes could not connect to the iPhone (or iPod) because an invalid response was received from the device.
I have no problem updating my iPhone 5, or my iPhone 6S+. but I can't update or add music to my 2 older devices (BTW - I use them for the gym and in the car as music players)
I have looked and tried the solutions people had a few years ago with other versions of iTunes and issues with these older devices. I have reset to factory setting on both devices, deleted old back ups, did the whole restore from file and from iTunes (which is weird because it recognizes the devise in restore mode). The system profiler shows the iPod or iPhone in the "USB" devices when plugged in so I'm stymied as what the problem is. I am also ****** because I lost some old apps, that are no longer available or have been upgraded and no longer have support for older iOS versions.
Does anyone have a fix for this, or is there any 3rd party software that you can use to do this. I tried iMazing, but it too does not recognize these devices in their new versions.
Any help would be greatly appreciated.
I am running macOS High Sierra, version 10.13.6 - only because some programs I have and need are not 64 bit, and not supported according to System Information > Software > Applications
iMac, macOS High Sierra (10.13.6)
