This command solved my problem. However, I would suggest that for those with little knowledge of Mac, please do the following steps: 1- Go to Application 2- Go to utilities 3- Go to Terminal 4- copy and paste this command in full : sudo killall -STOP -c usbd 5- press Enter 6- It will prompt you for your password, and type your password and hit enter 7- connect your iPhone to mac 8- The problem should be resolved Best of luck
