iTunes does not recognize iPad Pro

Before you respond to my question, please understand that I have already exhausted the suggestions in these articles to no avail:

If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support

If you see Error 3194, Error 17, or 'This device isn't eligible for the requested build' in iTunes - Apple Support

Device details:

iMac (Mid 2011)

High Sierra 10.13.6

iTunes 12.8.0.150

iPad Pro 9.7” (2016)

IOS 12.0.1

• When I initially connected the iPad with the accompanying USB/Lightning cable, iTunes asked me if I trusted this device and I answered Yes.
• While connected, the iPad is recognized by the iMac (see screen shot) but not by iTunes.
• The iPad Pro is visible when connected to our Mac Mini in our media area.
• I have the latest version of everything on both devices.
• I’ve rebooted both devices
• I have no security software.
• My Firewall settings are off.
• I checked my host files.
• I tested TCP port connectivity, but wasn’t sure what to do about it.

If no one has a new solution or explanation, I will naturally contact Apple Support.

Thanks!
