How to Fix the “Untrusted Enterprise Developer” Issue With Ease

iPhone errors can be a tad frustrating to deal with, regardless of when you see them appear. Some people get an error when syncing their device with iTunes; other people get errors just trying to log into their iCloud account. In recent months, though, a common complaint we've seen iPhone users ask about is the Untrusted Enterprise Developer error.

Generally, this error only appears when users attempt to install an application. In most cases, it is with third-party applications that aren't available on the app store. If this is a problem you encounter, read on and find out what you can do to fix it.

What Causes the “Untrusted Enterprise Developer” Error?

The name of the error itself suggests that if an app is made by an untrusted developer, that would be the key reason for the error occurring.

Apple's App Store has thousands of apps available, and just as many games. With such a wide selection available you might wonder why people turn towards third-party apps. Third-party apps are apps that users can't download through the App Store, and this is usually because they break the terms and conditions of the App Store.

For example, apps that promote illegal streaming or any sort of illegal activity is not allowed. Therefore, if a developer attempts to put this type of app on the App Store, Apple will instantly refuse. So, the only way to get these apps is through an external website.
By downloading apps outside of the App Store, you risk damaging your iPhone. Apple has several security measures in place to prevent harmful apps from causing damage, including the Untrusted Enterprise Developer warning. Now that you know why you may see this error, is there anything you can do to avoid it? Know more about what is Showbox.

Steps for Fixing “Untrusted Enterprise Developer”

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

Step #1 – Start by downloading the app from whichever website it is available on.

Step #2 – After the download is complete you must not open the app yet. This is a crucial step.

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

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


Step #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.


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

If you download a lot of third-party apps from different websites, you will need to do this for every developer. However, if this is a one-time process, you only have to fix the Untrusted Enterprise Developer error once.

Note that there's no guarantee this will work, which is why we highly recommend the other solutions first.
