‘Trust This Computer’ Alert Not Showing Up on iPhone? Here’s the Fix

Whenever an iPhone or iPad is connected to a computer for the first time, a popup appears on the screen asking users whether they trust the computer. And, they need to trust the computer to allow it to sync with the iOS device, access its photos, contacts, and even create backups. From what I have experienced, the trust settings work reliably most of the time – barring a few rare hiccups. Unfortunately, some iDevice users have reported that “Trust This Computer” alert is not showing up on their iPhone. As a result, they aren’t able to sync their devices with the computer. If the issue has traveled to you as well, you are at the right place to sort it out.

Fix “Trust This Computer” Alert Not Showing Up Issue on iPhone and iPad

So, how are we going to fix this problem? Good question. Let’s break it down first up!

What’s the Workaround?

Well, we will first try out a simple yet effective solution that often clicks in troubleshooting such common hiccups. If that fails, we will reboot the trust setting. In most cases, it can get the job done. Even if that doesn’t come to rescue you, we have some other reliable hacks to get over the line. So, needless to worry about the problem. Having said, let’s get into the troubleshooting mode, shall we?

1. Force Restart Your Device

The hard reset has often worked for me in fixing the “Trust This Computer” popup not appearing problem. So, I’m going to bank on this reliable troubleshooter to click this time as well.

First off, disconnect your device from the computer and then force restart your mobile device.

  • On the iPhone/iPad with Face ID: Press and release the volume up button, press and release the volume down button. In the end, hold down the side button for about 10 seconds until the Apple logo appears on the screen.

  • On iPhone/iPad with Touch ID: You need to hold down the Home and sleep/wake buttons at once for about 10 seconds to force restart your device.

After your device has restarted, connect it to the computer again. Now, enter the passcode to unlock your device. Next, wait for a few seconds for the “Trust This Computer” message to appear. If it pops up, you are ready to go. If it doesn’t, head over to other solutions.

2. Reset Trust Settings

Another trick that has proved reliable in resolving this issue is resetting the trust setting. For those unfamiliar, it’s the part of “Reset Location & Privacy settings” and works effectively in putting trust settings to factory default.

Rest Trust Settings

Head over to Settings app -> General -> Reset -> Reset Location & Privacy. Next, enter your passcode and hit Reset Settings again. Next up, try to connect your device to the computer to see if you have found success or not.

3. Reset Network Settings

If the above two solutions didn’t work, try resetting the network settings. Keep in mind, it will remove all the existing Wi-Fi networks and passwords, VPN and APN settings along with cellular settings. Yeah, it’s a radical solution and not many may want to go for it. But I would recommend you not to miss it out as it has a very good track record of fixing this problem.

Open Settings app -> General -> Reset. Now, tap on Reset Network Settings and confirm.

  • Just in case you have downloaded iTunes for Windows from the Microsoft Store, ensure that iTunes Mobile Device Helper is enabled as a startup item.
  • Click on the Start button and choose Settings. Then, click on Apps and select Startup. Now, ensure that the iTunes Mobile Device Helper is turned on. 

4. Update Your Mac/iTunes for Windows

If the problem is yet to be sorted out, the outdated version of macOS or iTunes may be at fault. Miscellaneous issues tend to often crop up when using the old versions of the software. Therefore, the software update would be the right way to go.

To update your Mac: Click on the Apple menu at the top left corner of the screen and choose System Preferences. Now, click on the Software Update pane and then follow the usual steps to upgrade to the latest macOS version.

  1. Configurator 2 only worked for me too. I found the problem only after using it. The problem was I was using the wrong password to decrypt the backup but Mac Finder didn’t let me know that. Thank you very much for the answer. Really helped.

  2. Was searching for the answer to this. If you are running BigSur and your phone shows up in Finder and is currently not “trusted”, click on your phone in the sidebar in Finder. You should be shown a screen that will give you an option to “trust” your phone.

  3. I Found another solution. Download the Itunes app for pc, and if your phone is connected via usb it will recognize it and the option will appear on the phone when you launch the app.

    1. Usually the just comes up as soon as I plug it in. Thanks for this tip, worked for me! Opened iTunes, and the alert popped right up. Clicked Trust on phone and Cancel>Quit on iTunes.

  4. Tried everything listed here, including upgrading to the latest Mac OS. Nothing. Configurator 2 worked instantly.

  5. none of the above worked on my iphone 12 – frustrating not being able to connect to itunes. Everything is up to date on windows and IOS
