My computer doesn’t recognize my iPhone

iPhone not recognized by computer

Updated: July 13, 2023

Your iPhone doesn’t connect to your computer or doesn’t appear in iTunes? Perhaps there is a hardware failure. In this article, we have collected the most likely causes of the problem and described ways to fix it, which will help you to solve the connection problem.

Defective connector

Most owners keep their phone in a pocket or a bag. As a result, dust and small debris can easily get into the connector and damage the contact. If this happens, blow out the connector with a jet of air to blow out the foreign elements.

Sometimes the connector fails due to careless use – connecting and removing the cable with force, being hit when dropped, or improperly connecting the charging and data cable. If your iPhone doesn’t charge and work with other computers, the connector may be damaged or there may be a line break on the circuit board. In this case, contact a service center for diagnosis and troubleshooting.

Problem with the USB port on the computer

When you are going to use a desktop computer, connect your phone to the ports on the motherboard. Using the ports on the front panel as well as USB hubs and extension cords often causes malfunctions in the phone. 

USB port failure cannot be excluded either. More often the problem is caused by the unavailability of drivers or a failure in their work. In this case, updating or completely reinstalling the driver can help. Additionally, use another connection port.

Faulty synchronization cable

Extensive use of the cable for charging and transmitting data causes it to wear out more quickly. Also, the potential reasons are temperature fluctuations, regular twisting and unrolling, and crushing of conductive cores inside the cable. Connect another cord to the phone, if the problem disappears – replace the cable. If the new cable does not work and the old cable works with other devices, the cause is may be in the phone or power connector.

Operating system failure

Errors in the computer’s operating system are not uncommon, in particular after a virus attack or a residual system infection. Reboot your computer. If this does not help, scan the operating system with an antivirus program.

Sometimes the failure occurs in the iPhone. In this case, you should restart the phone. Usually, this simple operation solves the problem.

If a “Trust this computer” window appears on the computer, you must unlock the phone and select “Trust”. This will reduce the likelihood of malfunctions later on.

Outdated drivers

Regularly update your phone drivers and iTunes software to avoid crashes. If you don’t, one day you may not be able to connect. If the drivers and software are okay, reinstall the drivers and iTunes application.

Make sure your iOS or iPadOS device is turned on, unlocked and on the Home Screen. Check that you have the latest software on your Mac or Windows PC. If you’re using iTunes, make sure you have the latest version. If you see a Trust this Computer alert, unlock your device and tap Trust. If you can’t unlock your device because you’ve forgotten your passcode, find out what to do.



This article covers the most common reasons when a computer can’t see your iPhone, and how to solve them. The most common cause is a failure of software or drivers. Such problems are solved by rebooting the phone, updating or reinstalling applications. Rarely, the problem is in the cable or power connector. If the problem is not solved, contact Apple Support.
