What can happen to the macbook?

Question

macOS

Hello! bought a macbook, but when you connect any device (ipad or iphone) via usb to the laptop, all devices immediately start behaving like crazy, i.e. it shows the device on recharging, then it does not charge, and so on ad infinitum. I can no longer explain this situation more clearly on my fingers) I tried to find something on the Internet, but I didn’t find anything (((
Who had this situation ???

Answer 1

It happens to me - it's all about the cable.

Answer 2

Tried to shove through different wires and into different connectors? Are the symptoms the same?

Answer 3

Most likely, the usb bus is closed, this happens after exposure to liquids. Take it to service.

Answer 4

in fact, it's either in the cord, or more precisely in action))
First you need to unlock the lock screen by entering a password (if any), then a window will pop up on the iPhone (trust this device), feel free to click trust (or trust), and it seems to be everything should work!
It happened with a poppy book in 2007, that's exactly how everything happens))

Answer 5

Issue resolved!
it was the originality of the wire, that's all!
