iPhone says I have to update my sw
Dear all,
after upgrading to Catalina it happens that when I connect my iPhone to my Macbook through an USB port (just for charging the phone), iPhone starts beeping continously and a message says I have to update my sw. Here is the link Se vedi un messaggio che indica che per connetterti al tuo dispositivo iOS devi aggiornare il software su iPhone, iPad o iPod touch - Supporto Apple (IT) where Apple explains what to do in such a situation (unfortunately the link connects to a page in italian language! I wasn't be able to find the same in english!)
My iPhone has the newest iOS available (15.5).
What does it mean that I have to update my sw? Have I to upgrade my MacOs? I don't believe that it is necessary to do so!
When I was working with High Sierra it happened that the same message was shown but -after clicking on the button "not now"- I could go further witout any problem.
Thank you if you can let me understand what can i do...
