Why Does My iPhone Keep Connecting and Disconnecting from Mac

There could be several reasons why iPhone keeps connecting and disconnecting when plugged into Mac. The most common reason for this inconvenience is the issue with the cable; either the cable is not working, you have not plugged in correctly, or you are using a non-Apple authorized cable. If that's not the case, your iPhone might be disconnecting due to a hardware or software issue. In case of a software problem, you can restart your Mac or iPhone device and re-plug it.

Way 1: Check the Basics

Before moving on to the complex fixes, perform the basic checks. You can check your cable by attaching it to your iPhone charger and plugging the charger into a socket. If iPhone charges, then the problem is not with the cable. Using defective, damaged, or non-Apple cables will create disturbance as well. Change the cable and connect it to the port. Because sometimes, software bugs can be the cause why Mac connects and disconnects iPhone. Also, check the charging port on your iPhone and iPad and remove the debris. Minor bugs often cause connectivity issues. Restarting them removes the bug and clears cache and garbage from memory. If restarting doesn't seem to work, make sure your devices are upgraded to the newest version. It helps you avoid multiple software issues.

Way 3: Reset iPhone Location & Privacy Setting

A lot of times when we have not connected our iPhones to Mac device for a long time, the system does not trust the device easily. iPhone connects and disconnects from Mac repeatedly can be fixed by resetting the iPhone location and privacy settings in your iOS device. Here's how you can reset your iPhone location and privacy settings.

Step 2: Find the Transfer or Reset iPhone option. In the Transfer or Reset iPhone option, tap on Reset button.
Step 3: Before the system erases everything, you will be asked to enter your passcodes.
Step 4: Enter your iPhone password and confirm.

Way 4: Restart the USBD Process

One solution that worked in our case when we had our iPhone connecting and disconnecting from Mac continuously is stopping or restarting the USBD process. To restart the USBD process, open the Terminal app from Spotlight and enter the command sudo killall -STOP -c usbd. This command pauses the USBD process. Then you can connect the USB cable and check the charging status. Unplug the device if the issue does not resolve and try the command "sudo killall -CONT -c usbd". It is the command for restarting this process. Pausing this process reduces the power output and device charges slower than usual. But it is effective to avoid the device connecting and disconnecting continuously.

SMC managed the amount of power sent to the USB port whereas NVRAM like None Volatile Random Access Memory stores settings for quick access. Here's how you can reset SMC and NVRAM settings on Mac.
