ouch - After Update, iPhone Sync Requires Catalina. Now they tell me!
I'm holding off updating my 2018 Mac Mini to Catalina till:
1) I finish exporting all my Lightroom Classic photos so I don't lose meta data, exif, and edits,
2) They say that updating won't break my Sonnet eGPU/RX580 configuration
I didn't know that I shouldn't update my iPhoneX to 13.1.3 because it won't sync with Mojave.
Bummer.
iPhone X, iOS 13
