Facing with the “Untrusted Enterprise Developer” error message when trying to install apps on your iPhone or iPad? Wondering how to get across this barricade, and install the apps on your iOS devices (iOS 13/12/11) without stress? Let’s show you how.

Why Does “Untrusted Enterprise Developer” Error Happens on iPhone/iPad

Although the Apple’s official means for installing applications on iDevices (iPhone/iPad/iPod Touch) is via the App Store, there are times when some users have to install apps outside of the App Store. This is mostly because there are some apps not allowed on the Store because they do not meet Apple’s terms and conditions. These apps may come from Xcode, Cydia Impactor, or other third-party websites, and they will bring up the popup message that states “Untrusted Enterprise Developer.”


This is to indicate that these apps are not trusted by Apple, and therefore users who want to install the apps, are solely responsible for the installation. Most of the time, these apps are rarely risky to your iPhone/iPad.
