After having upgraded to the latest version of iOS, many iPhone and iPad users find iOS 7 has brought a large number of new features to them, the good, the bad and the weird. One of the most annoying updates might be the “Trust This Computer” alert when you connect your iOS device to a new computer, especially a computer with Windows operating system.

Whenever you try to connect to a whole new computer, it will prompt you, asking whether you can trust the current device or not. If you tap on “Trust”, then it means all your settings and data will be accessible from this computer when connected. If not, the device will do nothing but just start to charge.

Accidentally Clicking “Don’t Trust”

What if I accidentally tapped on “Don’t Trust” and now my iPhone can’t sync with iTunes? You really didn’t meant to do that but accidentally, you tapped the wrong option.

How to undo this?

Usually, if you just disconnect the iPhone, wait for a few minutes and then reconnect it, you get the authentication dialog back again. But if that doesn’t work, we have to find other ways.

There are two ways to fix.

1. Resetting Dialog Warnings in iTunes

After you tapped on “Don’t Trust”, there’s actually no going back as long as your iPhone is connected and iTunes running. But there’s a reset-warnings option within iTunes which can work. Let’s first try that:

  • Disconnect your iPhone from the computer.
  • In iTunes on PC/Mac, click Edit → Preferences
  • Click on the Advanced tab
  • Click on the Reset Warnings button
  • Close iTunes.

Now, connect the iPhone back. If you see the Trust/Don’t Trust dialog come up, tap on Trust and the issue is now resolved. iTunes should be able to access your iPhone data.

2. Disconnect, Quit iTunes, Wait and Retry

The first method is usually a sure-shot way of fixing an accidental “Don’t Trust” click. 99.99% of the time, it works. In the rare event that it doesn’t work, this is what you need to try:

  • Disconnect iPhone from the computer
  • Quit iTunes on the computer
  • On the iPhone, go to Settings → General → Reset and reset all settings. (this doesn’t remove the data or apps. It just resets things like Wi-fi passwords and clears cache)
  • Open iTunes on PC/Mac.
  • Connect the iPhone.

(alternatively, you can switch off the iPhone and then plug it to the computer. This will power it on and the dialog shows up after the iPhone powers on)

Stop the annoying “Trust This Computer” message in your iPhone or iPad

This is a security strategy to block fake chargers, but it is unnecessary to keep popping up every time you connect to your personal computer. In fact, whether you choose “Trust” or “Don’t trust” your computer, it will charge. So, why not stop the annoying “Trust This Computer” message in your iPhone or iPad?


1. Go to Control Panel > Hardware & Sounds >  Device Manager
2. Right-click the Apple device > Properties > ‘Hardware’ tab > Properties > ‘Driver’ tab > Update Driver..
3. Search for the driver in “C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers”
4. The driver should be named ‘usbaapl64′

Fix #2

1. Go to Control Panel > Hardware & Sounds >  Device Manager
2. Right-click the Apple device > Properties > ‘Hardware’ tab > Properties > ‘Driver’ tab > Disable
3. The pop up should not appear anymore and the device will charge while plugged in

Fix #3

1. Control Panel > Uninstall a Program
2. Select ‘Apple Mobile Device Support’ and hit ‘Repair’

Fix #4

1. Remove all Apple programs from your computer (iTunes, Apple Software Update, Apple Mobile Support, etc.)
2. Restart computer and reinstall the latest version of iTunes
