iOS devices connecting and disconnecting rapidly.

iOS devices connecting and disconnecting rapidly. I've been having this issue for a while with my iPad Air 2: When I plug it into my MacBook, it will act as though I am plugging it in and unplugging it rapidly, and will not stay connected long enough for me to sync or backup with iTunes.

"You need to reset the privacy settings in IOS, then it will recognised again.

If you have not connected your iPhone to your computer in a while and the computer was updated with new software, there could be some trust settings issues. In order to check and resolve this issue, Open your iPhone, tap on Settings > General > Reset > Reset Location & Privacy."

"Sometimes, the issue is purely a software one. Occasionally, there are problems with usbd daemon programme, which is the root of the issue with the iPhone.

A possible solution to this problem is to open Terminal.app (Applications -> Utilities -> Terminal) and execute the following command: sudo killall usbd . It will kill the programme and it will immediately relaunch. You will need to provide your password. Please note that the password will not be visible, it is normal.

If it does not work, try entering a different command in Terminal: sudo killall -STOP -c usbd . Once more, you may need to present your password"

Mine always does that. I think it's because battery is not charged enough.
