Many iOS users often see the popup that says, “Untrusted Enterprise Developer” when trying to install apps outside of the App Store. These are the applications that were not allowed by Apple due to their term and conditions. But in most cases, they do no harm to our iPhone and iPad.
If you’re new to the whole emulators and third-party apps thing, this would be the first or second error you see. But that’s fine because there is an easy way to fix the untrusted developer popup.
Why does this error appear in the first place?
Like I mentioned earlier, the popup only displays for apps or emulators that have been installed from Safari or sideloaded via Cydia Impactor. Since regular users are the one who installed them, they’re responsible for the apps they downloaded to their device. As a result, Apple added the warning to iPhone and iPad running iOS 9 and higher.
You will see the complete notice below.
Untrusted Enterprise Developer” along with iPhone Distribution….has not been trusted on this iPhone. Until this developer has been trusted, their enterprise apps will not be able to use.
The fix to this issue is relatively simple. If you believe the app you installed will not inject or do any harm to your iOS device, then you can tell the system to trust it.
How to Fix Untrusted Enterprise Developer in iOS
After downloading the app, don’t open it yet. Follow the instructions below first.
- Go to Settings > General > Profile
- On this page, you may find several enterprise apps
- Choose the app corresponding to the app that iPhone doesn’t let you open
- Tap on the Trust button and another one to confirm
Now go back to your home screen and try to open the application. You shouldn’t have any trouble opening it since its profile has been signed personally by you, the device owner. This Untrusted Enterprise Developer prompt is another great way to hardening the security of your iPhone. This will allow you to trust non-App Store apps manually.
Next time if an emulator or app doesn’t want to open, you know the reason why.
For iOS 9.3.3 Users
Another recent situation with this error would be the new Pangu Jailbreak for iOS 9.3.3. You can now download the jailbreak utility and initialize it to install Cydia without a computer. However, to open the Pangu app, you will need to use this method above before opening it on your home screen. I hope this help and enjoy!
