Iphone wont connect to Mac
My IPhone 11 Pro Max won't connect to my desktop Mac.
When I plug it in it keep connecting and disconnected rapidly.
before I can click anything and the phone flickers between charging and not charging very quickly. I open the photos to back up and again it appears and disappears constantly...I tried every single cable I have both Apple and non Apple.
Today I get the ' This accessory may not be supported' message when I plug it into the wall charger it came with. Help please I'm going crazy! Many thanks
