Solution 1: Basic Check to Fix iPhone Connects and Disconnects from Mac

Many people don't know this, but if you go into iTunes Preferences -> Devices, then check "Prevent iPods, iPhones & iPads from syncing automatically," it will keep your iPhone from connecting and disconnecting. This is especially handy if you're using an older version of iOS.

If Wi-Fi sync isn't solving the problem for you, try turning off Bluetooth. Go into Settings -> General -> Bluetooth, then turn off Bluetooth and reboot both devices. Your iPhone should now be able to sync without connecting and disconnecting repeatedly.

Before doing anything else, check that the cable you're using is suitable! If the cable is damaged or even slightly bent, this can cause problems with connecting to other devices. Try another cable if possible, or an Apple-certified cable if not.

If you're using USB ports on an external monitor or another USB hub, try plugging your device directly into one of the ports on your Mac itself. Some hubs aren't powerful enough to charge an iPhone while it's also connected to a computer, so they might drop out when transferring data.
