Iphone XS Max not connecting with MacBook Air
I have an Iphone XS Max and MacBook Air. All up to date with IOS 14.3 and Big Sur 11.1. Every time I connect the two with a lightening cable, it repeatedly gives a File Not Found message (like hundreds of times so I have to disconnect) and keeps flicking in and out of connection, so can't even press the OK buttons. Any ideas.
I've tried loads of different cables, so it's not that.
