I get this prompt sometimes when I connect my phone to my computer. It doesn’t tell me what items it’s referring to, but I know I don’t want anything on my computer that isn’t there already. But it looks like if I don’t go ahead with it, the mystery items will be removed from my phone.
Anybody know what the thinking is behind this? Maybe it’s just a sync setting I’ve set myself, but it reads like some kind of crazy ransom note :)
I chose ‘Don’t Transfer’ in the end. I have no idea what the consequences are. I don’t notice any differences on my phone.
But these days purchases show up on both devices whether they’re downloaded or not. There’s a little cloud or arrow symbol beside them if I want to download them (eg Apple Music). So it’s confusing that there’s a separate policy that insist on both devices having the same content.
But I see in macOS Finder, when I navigate to my device there’s a checkbox enabled labelled “Sync music onto iPhone”. So maybe this is why (and I likely set that myself, I rarely ever connect my phone these days).
