iTunes (12.8.3) doesn't see iPhone 6s when connected to MacBook Pro running High Sierra
I had been using iTunes to backup my iPhone but for several months at least my iPhone doesn't connect to iTunes on my MacBook Pro (15" mid-2015) running High Sierra. iPhone is a 6S running iOS 14.2. When I check System Information, there is an iPhone listed in the USB device tree, but I can't tell if it's my current phone (or someone else's that was connected at some point).
I don't want to upgrade my OS because there is software on my MacBook that I need that isn't supported by later OS versions.
I found an earlier Apple Communities thread about this topic and very similar hardware/software here but the only answer to the OP's question was to un-install and then re-install iTunes. I'm hoping there is a solution that is more simple.
To summarize:
iPhone 6S (OS 14.2) isn't seen by iTunes 12.8.3 on a mid-2015 MacBook pro Retina running macOS High Sierra (10.13.16)
Thanks for any help.Ernst
