Earlier today I installed the macOS Mojave 10.14.6 Supplemental Update on my MacBook Pro 2017 15-in.
Afterwards I connected my iPhone 7 (iOS 12.4) to the computer and opened iTunes, which said, “iOS 12.4: Your iPhone software is up to date.”
Also, when I clicked Check for Update, it said, “The version of the iPhone software (12.4) is the current version.”
Then, when I opened my iPhone and went to Settings > General > Software Update, it offered to update iOS to 12.4.1, which I did.
My question is, why the discrepancy?
