It was working fine a month ago. Heck, it was working fine yesterday! But today that iPhone is not connecting to a computer. Don’t worry, it’s happened to the best of us and we’ve got the fix you need.
Many reading this may be first-time iPhone owners after a very merry Christmas. Others might have owned iPhones for years. This issue is totally indiscriminate. But whatever your background, we’re gonna start this article by getting everyone on the same page.
With your iPhone powered on, unlocked, and on the home screen, connect it to your computer using a lightning-to-USB cable. Upon doing so, your computer should automatically open iTunes, but if not you can help it along by opening it yourself.
You should notice that your iPhone is now drawing a charge from the computer, shown by a lightning bolt in the menu bar. Keep an eye on your unlocked iPhone and if prompted to Trust this Computer be sure to go ahead and tap Trust.
Once that’s done, you should see a small iPhone symbol towards the top left of the iTunes window. Clicking that will show all the content currently on your iPhone and allow you to download whatever else you want on there.

Sadly, things don’t always run so smoothly.
If you followed the process above but still your iPhone is not connecting to a computer check out the troubleshooting tips we’ve laid out below. We’ve ordered the sections ranging from most to least common causes, be sure to retry your iPhone connection after each stage.
Update Your Software and Restart All Devices
With any issues like this, the first step is always to check for software updates. Occasionally software problems arise and the only solution is to update to the latest software where the bug has been removed.
To be clear, you should check for and install any updates for your:
iPhone software
iTunes version, and
Mac or Windows operating system
With all the latest software downloaded and installed, restart every device and try connecting again.
Test All Ports and Cables
The last thing you want is faulty hardware, but that doesn’t make it any less likely to be the problem.
Different Cables
Get your hands on a second Lightning-to-USB cable in case yours has gotten damaged. There are a couple of important things to note with regards to these cables:
Even if a cable charges your phone, it still might be unable to connect to iTunes
Only official Apple or Apple MFi-Certified cables will work when connecting to iTunes. That’s why they’re more expensive.
Different USB Ports
Unplug every external USB device from your computer. Not only does this allow you to test your cable in each port, but it reduces the risk of one of these devices interfering with the connection somehow. Don’t worry, you shouldn’t need your mouse or keyboard for the moment.
Periodically connect your iPhone to each port on the computer, allowing time for iTunes to recognize it to test if any other ports allow a connection.
Difference Devices
Beg, borrow or steal another Apple device (preferable another iPhone) to test with your computer. If another device connects to iTunes without issue, there must be a problem with your iPhone. This could be in need of a software reset or it could be due to a damaged lightning port.
If that doesn’t illuminate anything, try connecting your iPhone to another computer that’s running iTunes. Should this work it means there’s an issue with your computer somewhere, and you should seek professional assistance.
