iMac will NOT recognise iPhone 6S !?
Concerns: "If your computer doesn't recognize your iPhone or iPad".
I checked all steps on this webpage, but still my iMac (late 2013, macOS Catalina 10.15.7) will not recognize my iPhone6S (OS 15.7.1).
When directly connecting with a USB cable, the Photo app immediately starts up and after some time it (sometimes!) shows all photos on my iPhone, so there must be some occasional or temporary connection between both.
My iPhone shows in the Music App, but when selecting the iPhone, it shows contents but will not properlly sync. Last time it synced, a number of my songs will no longer play (due to "content not available in your country", which is BS of course because they all played fine during the last years!
The iPhone however does not show in Finder windows.
I can allso find the iMac on my iPhone if I want to airdrop a picture from my iPhone, but it takes a very long time before it actually drops.
