Untrusted Enterprise Developer

Let’s face it, we’ve all been there – trying to install a new app on our iPhone or iPad, and suddenly we’re faced with the dreaded message: “Untrusted Enterprise Developer“. What does it mean, and how can we fix it? Stick around, because we’re about to take a deep dive into this issue.

Understanding the ‘Untrusted Enterprise Developer’ Issue


So what causes this ‘Untrusted Enterprise Developer’ issue? Simply put, it’s an iOS security feature. When an app hasn’t been downloaded from the App Store, iOS can’t confirm its authenticity, thus considering it an ‘untrusted’ developer.


As a result, your device may prevent the app from installing or running, as it tries to protect you from potentially malicious software.

iOS Security Mechanisms

App Verification Process

Apple has a stringent app verification process in place. Every app on the App Store goes through a rigorous assessment to ensure it doesn’t contain any harmful elements.

Enterprise Developer Program

The ‘Enterprise Developer Program’ is a unique scheme for organizations to distribute proprietary, in-house apps to their employees. Apps distributed this way bypass the App Store’s verification process, causing iOS to flag them as ‘untrusted’.

How to Trust an App on iOS

First, you need to locate the ‘Device Management’ or ‘Profiles & Device Management’ setting. You’ll find this under ‘General’ in your Settings app.

Trusting the Developer

You’ll see a list of app developers under ‘Enterprise App’. Tap on the developer’s name, and you should see a blue ‘trust’ link.

After trusting the developer, you can trust their app. Tap on ‘Trust’, and you’re good to go!

Steps for Fixing Untrusted Enterprise Developer

Remember that unless you know a third-party iOS app is safe, you shouldn’t install it. If you see this error on your device, follow these steps to get rid of it.

#1 – Start downloading the app from whichever website is available.

#2 – You must not open the app yet after the download. This is a crucial step.

#3 – Launch the “Settings” app and swipe down to “General.”

#4 – Tap “General” and then select the “Profiles” (or Profiles & Device Management) option.

#5 – A list of developer profiles will be shown on this menu. Below the “Enterprise App” heading, tap the developer of the app you are trying to install.

#6 – Lastly, tap on the “Trust Developer” button and confirm this decision.

You will need to do this for every developer if you download many third-party apps from different websites.

However, if this is a one-time process, you must only fix the Untrusted Enterprise Developer error once.

What to Do if the Issue Persists? Try Dr.Fone Toolkit

Should the previous step-by-step guide not help you get around this error, there is an alternative option.

Dr.Fone Toolkit is a fantastic iTunes alternative that includes many features that iTunes doesn’t. You have full control over your iOS device’s data, and here are some of the key features it offers:

  • Repair your existing iOS installation without wiping your data
  • Transfer data between your iOS device and PC or between iOS and Android
  • Instantly transfer personal data from one iPhone to another
  • Supports data management of contact information, texts, photos and videos, music, and much more
  • Repair your iTunes installation without losing the existing data in your library
  • Transfer apps that you previously synced to your iPhone with iTunes

Dr.Fone Toolkit has versions that support both iOS and Android devices. Although our concern is with iOS devices, if you have an Android device that faces similar errors, then know that hope isn’t lost! Dr.Fone can help with the Untrusted Enterprise Developer issue and many others.

Managing Your iPhone Data with Dr.Fone Toolkit

For this process, we will use Dr.Fone’s Manager feature. If you have previously installed the app you are having problems with and have, at some point, synced it with iTunes, you’re in luck.

If that’s the case, you’ll be able to transfer it over to your iPhone again and shouldn’t have any issues.

#1 – Download and install the Dr.Fone Toolkit program on your computer. You must purchase the full version for limitless access to all its features.

#2 – Connect your iPhone to the computer with a lightning cable, and Dr.Fone will detect the connection.

#3 – On the main menu of Dr.Fone, click on the “Phone Manager” feature.


#4 – Click on “Transfer iTunes Media to Device” from the menu you now see.

Note: if you only want to transfer specific files, use the relevant tabs at the top of the interface. For example, select “Photos” to manage or transfer photos exclusively.

#5 – A pop-up window listing all compatible data types will appear. Go through the list and select the data types you want to transfer from iTunes to your iPhone.

#6 – Finally, click on “Start,” and Dr.Fone will take care of the rest. The transfer should take just a few minutes.

Transfer from iPhone to iTunes

Of course, you can’t transfer it back if you don’t have the app that gives you a developer issue in your iTunes library.

However, Dr.Fone Toolkit is a fantastic alternative to iTunes. You can easily transfer your data, and several other features are incredibly useful.

Can Dr.Fone Toolkit Manage iPhone Apps?

Yes! Just like your photos, videos, and plenty of other data, Dr.Fone can help manage your apps too. With the program, you can:

  • Import apps from your computer and install them on your iOS device
  • Export apps that you currently have on your iOS device
  • Delete apps in bulk (incredibly useful when you don’t have a lot of storage)

So, if you’re angry about dealing with the Untrusted Enterprise Developer issue, you can use Dr.Fone Toolkit to sort it out.

“I Still Get the Untrusted Developer Error?”

After trying both of the solutions above, it’s unlikely that you will still encounter this problem.

However, if you do, it could be a problem with the iOS firmware. In this case, you might want to consider a factory reset or using Dr.Fone’s Repair feature.

As we said before, this feature won’t affect your data. Follow the steps below for more information on this process.

Step #1 – Launch Dr.Fone Toolkit and connect your iPhone with the appropriate lightning cable.

Step #2 – Click ” System Repair ” from the main menu.”


#3 – The following menu will present three repair options and for this method, click on “iOS Repair then “Standard Mode.”

#4 – Choose a device model and select the iOS version on your iPhone.

Select iOS System Version

Note: you must select the current model and iOS version here; otherwise, you risk losing personal data.

#5 – Click “Start” and wait for the new iOS firmware to download. The download could take a while, given the large file size of iOS updates.

Download new iOS firmware

#6 – Once the download is complete, click on “Fix Now,” and the new firmware will now install.
