Does Not Appear Trust Computer Iphone

Typically, the vast majority of users use iTunes to pair an Apple device with a computer. In this article we will try to answer the question of what to do if iTunes does not see the iPhone.

Today we’ll look at the main reasons that iTunes cannot see your device. Following these recommendations, you are most likely to be able to solve the problem.

Reason 1: damaged or non-original USB cable

The most common problem that occurs due to the use of non-original, even Apple-certified cable, or the original, but with existing damage.

If you doubt the quality of your cable, replace it with the original cable without a hint of damage.

Reason 2: devices do not trust each other

In order for you to be able to control your Apple device from a computer, trust must be established between the computer and the gadget.

To do this, after connecting the gadget to the computer, be sure to unlock it by entering the password. A message appears on the device’s screen. "Trust this computer?" , with which you need to agree.

The same is with the computer. A message appears on the iTunes screen asking you to confirm the installation of trust between devices.

Reason 3: malfunctioning computer or gadget

In this case, we suggest that you reboot the computer and the apple device. After downloading both devices, try reconnecting them using the USB cable and iTunes.

Reason 4: iTunes crashes

If you are completely sure that the cable is working, the problem may be with iTunes itself, which does not work correctly.

In this case, you will need to completely remove iTunes from the computer, as well as other Apple products installed on the computer.

After completing the procedure for uninstalling iTunes, restart your computer. After that, you can proceed to install the new version of iTunes, after downloading the latest distribution kit from the official website of the developer.

Reason 5: Apple device malfunctioning

Typically, a similar problem occurs on devices that have previously been jailbroken.

In this case, you can try to enter the device in DFU mode, and then try to restore it to its original state.

To do this, completely disconnect the device, and then connect it to the computer using the USB cable. Launch iTunes.

Now you need to enter the device in DFU mode. To do this, hold down the power button on the device for 3 seconds, then, without releasing the button, hold down the Home button, holding both keys for 10 seconds. Finally, release the power button, continuing to hold “Home” until the device detects iTunes (on average, this happens after 30 seconds).

If the device was detected by iTunes, start the recovery procedure by clicking on the corresponding button.

Reason 6: conflict of other devices

iTunes may not see the connected Apple gadget due to other devices connected to the computer.

Try disconnecting all devices that are connected to your computer via USB (except for the mouse and keyboard), and then try to sync your iPhone, iPod, or iPad with iTunes again.

If no method has ever helped you fix the visibility problem of the Apple device in iTunes, try connecting the gadget to another computer that also has iTunes installed. If this method is also unsuccessful, contact Apple Support.

Friends, good day to all. Thanks to one of our commentators, I decided to write a post for you about trust issues that sometimes arise for owners of iPhones and iPads, after the version before iOS 7. Here’s what Kirill writes to us:

“Good afternoon, almost the same problem, but I managed to upload photos, but recently I dropped them again and clicked -“ Do not trust this computer ”, what should I do? When reconnecting the iPhone, this window of trust does not appear. "

This comment can be found in the article "". There is also a less popular situation where the user, on the contrary, entrusted his iPhone to the computer, but when he decided not to trust, he simply could not find where to click this button of distrust.

In general, the situation is somewhat ambiguous, for some iPhoen and iPad users, the Trust and Do Not Trust buttons appear each time you connect to the computer, for some it’s enough to select one of the buttons on the first connection and the window no longer appears and does not bother the user every time connecting to a computer. But in the second case, if you accidentally click “Do not trust”, the computer does not see the iPhone or iPad, and it doesn’t even work, since “My Computer” does not display the device.

Today we will make your iPhone or iPad show the window again with a choice – “Trust” or “Do not trust”. I don’t know if this method will help you, but it helped me. Before that I tried, Reset alerts and Reset sync history in iTunes settings did not help. I tried to apply both to the iPhone and iPad’s in different operating systems. Today we will take a closer look at the call of the trust window using the operating systems Windows XP and OS X Maverick. If you accidentally clicked on the "Do Not Trust" button or just need to call up the trust window, then repeat:

Trust this computer – reset in Windows

At first I tried to find a reset of trust in the iOS settings in the iPhone and iPad’s, but did not find. It turned out that the reset of the trust system is still being done on the computer. In order for everything to work out in the Windows XP operating system, you need to enable the display of hidden files and folders, this is done as follows:

We go to "My Computer", lying on the desktop or in any other folder. In the context menu, select: Service – Folder Options (see image above). In the Folder Properties window that opens, select the View tab, below, in the additional parameters, look for and put a marker – Show hidden files and folders. Now click OK. (Earlier, we had already encountered Folder Properties when, using the same link, you can learn how to enable the display of hidden files and folders in Windows 7).

The display of hidden folders and files in the computer is turned on, now you can search for the Lockdown folder and delete the contents of this folder, which is responsible for trust. The main thing is not to delete the folder itself, only the files located in it.

    In Windows XP, this Lockdown folder is located in the following path:

C: \ Documents and Settings \ All Users \ Application Data \ Apple \

In Windows Vista, look for this folder here:

For Windows 7, 8, 10:

We go into the Lockdown folder, select all the files and delete them by right-clicking and selecting – Delete. That’s all, the next time you connect your iPhone or iPad’s to your computer, you will again see the offer – Trust this computer?

Mac OS: “Trust, Do Not Trust Appear”

In Mac OS, you do not need to display hidden folders and files, as in Windows. The principle is the same – delete the contents of the Lockdown folder.

To access the Lockdown folder, run the Finder program on Mac OS. After that, in the top line of the working screen, select the context menu: Go and select Go to folder.

In the window to go to the folder, write: / var / db / lockdown and press the button – Go

If the Lockdown folder did not open, then the post will help – ""

In the Lockdown folder that opens, there can be one or many files, select all the files and delete them by pressing – Move to the trash. The main thing is not to delete the folder itself.

On other operating systems, the trust window on iPhone, iPad, and iPod touch is also cleared by clearing the Lockdown folder on the computer. Now you know how to force a trust window and trust your iPhone and iPad iPad over and over again.

Details Updated 02.01.2017 12:29 Published 09/21/2015 13:23, iPad or iPod to your computer on its screen you will see a dialog box: “Trust this computer?”" and you’ll need to allow access to your gadget and its file system or refuse it. Therefore, when the message “Trust this computer?” Appears, a solution to the problems will be needed in any case, regardless of the gadget used.

What happens when you click the "Trust this computer" button

In the first case, when you click the Trust button, the computer will be able to receive personal information and files from the iOS device. At the same time, trust is assigned forever, so you should consciously make your choice, especially if the computer does not belong to the home category, and the files are exclusively personal.

In the second case, when you click the "Do not trust" button, the iOS device will simply charge, but you will not be able to access the file system from the computer. When you reconnect the device to the same computer, a dialog box will appear again and if you encounter it may be required for absolutely any iPhone, iPod or iPad, since some devices do not give full access even after confirmation.

This function is quite simple and usually does not create any problems for users. But in some unpredictable situations, the "Trust" button does not give access and your computer does not see the device, and, therefore, iTunes does not see it either. In this case, even through the "Explorer" the user will not be able to view photos and transfer them to your PC.

Trust this computer: solutions to problems.

There are two ways to solve this problem:

1. Reset alerts in iTunes. This method does not always help, but if there are problems, then you can reset the warnings as follows:
– disconnect the iOS device from the computer;
– run the Tunes program and go to its settings;
– find the tab "Add-ons" where to click on the button "Reset alerts".

2. If resetting the warnings did not help to solve the problem and you cannot get information from the device, you need to check for iTunes program updates and update it to the latest version from the official Apple website. After that, the computer must be restarted and all the steps for connecting the device again.

In some cases, malfunctions may be due to a cable or USB port malfunction. If the problem persists, you must reset.

Several features aimed at improving system security were introduced. Among them is a new way to connect devices to a computer.

When connecting an iOS device to a computer, a window appears on it, on which you need to select the option "Trust". Only then will a Mac or Windows PC connect to your iPhone or iPod touch via USB.

This function not only warns you that you are trying to connect to a new computer, but also prevents computers and accessories from receiving data from devices without your consent.

By clicking Trust, you give your computer access to your data.

Previously, this only required the device to be unlocked when connected.

In iOS 11, you also need to enter your password. This provides an additional layer of protection against data theft.

To connect a device with iOS 11 to a computer, you need:

  • Connect the device to the computer via USB.
  • Unlock device
  • Click "Trust" on the pop-up window.
  • Enter the password on the device.

A significant role in the appearance of this feature was played by the new Face ID biometric authentication method on iPhone X.

Previously, anyone who has access to your unlocked device could connect it to a computer and use a special program to extract various data from it, such as personal videos and photos, voice notes, documents, etc.

If you suddenly suspect that your device was previously connected to some third-party computer without your knowledge, you can disconnect by resetting the location and privacy settings.

In theory, a hacker could even save a full copy of your device via iTunes by connecting it to his computer. This way you can extract even more personal information. For example, dialogs from Messages, WhatsApp and other instant messengers, voicemail, call history, contacts, calendars, notes, bookmarks, Safari history and much more.

As mentioned above, connecting an iOS 10 device to a computer was much easier. Because of this, you would be in great danger if someone had access to your unlocked device. That is why the new iOS 11 feature is very important.

Experience shows that at customs, tourists are often asked to provide a password for their device if employees suspect something. In the USA, you have every right not to disclose your password.

You can enter the wrong password several times, and this will lead to the complete deletion of data from the device. To activate this function, go to Settings Touch ID and password code (or Face ID ) → Erase Data and click on the switch next to it to turn green.

Now you know why the new iOS 11 security feature is so important.
