itunes no longer supports ipod classic
I think my question comes down to, "how can I downgrade to the previous version of iTune?"
Here's the background...
After the bad idea of "upgrading" to High Sierra, and working through an endless list of problems, I just ran into a new one. iTunes will no longer recognize my iPod. It's the Classic 160GB (the best iPod ever).
The iPod shows up in the System Report as a USB device. It also shows up on the desktop as a volume. Clearly the Mac recognizes it as an iPod and a working USB device.
iTunes refuses to show it in the list of devices.
In a chat with Apple support, I was told my iPod is no longer supported.
Looking in the Console, I found message from iTunes such as these. This seems to confirm that iTunes no longer recognizes or supports the iPod classic.
