macOS must have downloaded and installed the latest iTunes during the last software update. It’s the awful one where they removed the mobile app store, without replacing it with a standalone program or anything. #picardfacepalm.
The good news though, there’s a File Sharing section now, where you can upload files to specific apps on the phone. A semblance of sanity prevailed.
Out of interest, the first iTunes I ran was on Mac OS 9 back in the day, but iTunes 7 was the first to be reviewed here. Looking at those screenshots from a decade ago reminds me how far we’ve come, or haven’t come. Wow, that navigation looks so clean.
Now to wait for iOS 11.1.
