iPhone se 2020 won't connect to Macbook running El Capitan
When I try to connect my new phone (running 13.5.1) to my laptop running el Capitan, I get the notice that I need to download software so it will connect. However, each time, after downloading, it says it can't install.
I have most recent iTunes. All updates done.
Any ideas? I need to connect to iTunes on my computer so I can restore my backup to my new phone.
MacBook Air 13″, OS X 10.11
