When your iPhone is not detected on your computer, this can cause serious inconvenience. iOS system good, but not perfect: system recovery may be required due to memory consumption by some applications. Also iTunes becomes necessary for fast loading videos, music, movies and saving data on a computer.

What to do if one day you connect your iPhone, a computer or yourself iTunes program refuse to see him? We suggest using the recommendations that should help solve the problem of identifying an iPhone.

Checking the cable

On latest models iPhone (since iPhone 5) manufacturers began to use the Lightning interface. The 8 pin connector is designed not only for a high-quality connection, but also has a certain system protection against the use of non-original cables.

A small chip is built into the cord, which makes a decision whether to work with such a cable or not. Manufacturers of non-original accessories have learned to create cables with similar chips, but they work exclusively for charging. And it becomes impossible after a couple of months of use. Conclusion: the cable must be original (if the cord included in the package is torn, we buy it).

Solving a problem with Apple Mobile Device

Let's take a closer look at how this is done on Mac OS and Windows.

  • Disconnect your iPhone from your Mac;

After this, the iPhone should be recognized by iTunes.

Users iPhone phones, since iPad and iPod owners sometimes connect their mobile devices to the computer so that using the program . Some ancient comrades, including us, use Windows XP as their operating system the old fashioned way. But it seems that Apple is slowly ceasing to support this not-so-young program.

I’ll tell you using an example that we encountered today.

After downloading installation file We try iTunesSetup.exe, but we get the following notification:

iTunes requires Windows 7 or later to be installed on your computer

Clicking OK followed - The iTunes installer has completed and the installer has encountered errors.

After surfing the Apple website, I found the answer, it turns out that the final version is for Windows XP and Vista - iTunes 12.1.3. Accordingly, in our case, two methods will help:

Updating iTunes

Since in our computer old iTunes already existed, we decided to just update it. By pressing Alt keys called up a menu in which they selected the Help section, in this section they clicked Updates.


iTunes found in its built-in updates not the latest version - 12.1.3, as it was written on the Apple website for XP and Vista. The description for the update states that this update comes with iOS support 9 for legacy operating systems.

Download the old version of iTunes


After installing the update, the computer rebooted, we tried connecting our iPhone and iPad with iTunes 12.1.3 iOS firmware 9, iTunes saw them again and allowed us to work with them! The sad thing about this whole story is that the day will come when you will have to change your operating system or even your computer in order to use the next iOS firmware update.

Warm greetings to everyone! After updating the firmware on their iPhone or iPad, users may encounter such a big (I would even say gigantic!) problem that all other errors seem like just minor and insignificant troubles. What are we talking about? And now I’ll tell you everything in detail...

iOS devices have a wonderful (without any irony) “Find iPhone” feature. If it is enabled (), then during any action (be it resetting settings, restoring, flashing, etc.) in order to start using the gadget, you will be prompted to activate it - enter the Apple ID and password (those that were set before this operation). And here the most interesting, incomprehensible and often very sad begins:(

You try to enter the Apple ID and password that you have been using with this device for a long time, and a warning of this kind pops up: “This Apple ID cannot be used to unlock this iPhone.” How does this happen? After all:

  • Only you have used the device from the very moment of purchase.
  • Only one (exclusively yours!) Apple pair ID and password have always been used in iPhone\iPad.
  • In other places - on the Apple website, the web version of iCloud, iTunes, everything works fine and logs in. But it’s not on the gadget.

You persistently enter the correct connective from Email and password, but the device stubbornly tells you that everything is wrong and this pair is not suitable. Here are the input data.

Let's figure out why you can't activate the device with your Apple ID account. Go!

Case 1. In fact, the iPhone\iPad was initially activated with a different account

How can this be? But maybe. After all, even if you bought the gadget new, it’s not a fact that it actually was like that. Some sellers know how to hide iCloud lock. It seems to you that the device is not tied to any account, you enter yours and everything seems to be “OK”. But in fact, the first time you try to flash it, you get an activation lock - the device simply does not accept what you think is the correct Apple ID.

What to do? In most cases, this is a hopeless situation. It is no longer possible to contact the seller, which means it is impossible to obtain the correct login and password combination. As a result, we get a “brick”. The only way out- pretend that you forgot the necessary data and act. The purchase receipt will be of great help.

Case 2. Error on Apple's part - solved automatically

Yes, yes, Apple also messes up sometimes. And this “sometimes” happened relatively recently, when iOS update up to version 9. Many people received an error after the update - “ Incorrect Apple ID. It cannot be used to unlock this iPhone, please enter other information." And in fact they were left with a non-working device in their hands. Apple tried to fix everything quickly and released timely update and assured me that it wouldn’t happen again. But is this true!?

Moreover, as users write, the first line of operators does not understand what they are talking about at all. You explain to them that there is only one Apple ID, you know it, the gadget prompts you to enter the correct account pair (the device displays several letters from your email - and they match yours!), but they will persistently kick you off and say that when correct data error "Apple ID cannot be used to unlock this iPhone" is not possible.

What to do? Don't shout, don't rage, but stick to your line. Claim that the device is yours and you want to use it. And thereby try to get to the second line of tech. support. They are usually more competent. However, be prepared, you may be asked for answers to Control questions(if you don’t remember, change it in your account settings on the website, because you have access there!). And in especially difficult cases, a purchase receipt as proof that the gadget belongs to you. Although, given the fact that you know the entire Apple ID and password, the matter most likely will not come to evidence.

operating room Windows system full unpleasant surprises. Habitual processes - downloading, changing users, installing applications and others - can fail at the most unexpected moment. One of the problems that a user may encounter unexpectedly is an error with the message “The key cannot be used in stated condition" Eliminate this error quite simple, and you can do it without Windows reinstallation, data loss and calls to the service center.
