If you use TutuApp third-party app installer regularly, you might be wondering why it’s suddenly stopped working. There’s a good chance that it’s down to Apple revoking the app certificate, causing TutuApp to crash. And, when it goes, it will take all your media apps and movie apps with it. So, why does Apple revoke app certificates, and what can we do about it?
Why App certificates Get Revoked
Many of the third-party installers are built on expired enterprise app certificates, and, over the last couple of weeks, Apple has stepped up its game, revoking them left, right and center. Usually, the app developers manage to find another certificate and use it before you even notice there is a problem, but things have gone awry recently. Simply put, there are few certificates left to be had, and those that are available are just too expensive.
Hang on, you mean these certificates have to be paid for?
Yes, they do. When you install a third-party app, most of the time, you will get an untrusted developer error popup and, in 99% of cases, the developer’s name on the error message is Chinese. Now, certificate selling has turned into a huge industry in China, albeit a hidden one. How they work is that rent p12 files or recycle enterprise certificates. Then they sell on to their downstream, at an inflated price. Their downstream raises the price again and sells it on, and so it goes on.
Sadly, it isn’t just these sellers involved; some of the app stores themselves do the same thing – use the certificate and sell it on. Ignition app is the perfect example of an app store that does this and, in this way, these certificates are being constantly used and sold, making it easy for Apple to discover and revoke them.
The people that suffer the most are people like you; those who just want an easy, trouble-free way of downloading their apps. Sadly, because of the fact that this has become such a huge business, third-party apps are crashing within a few hours of installation and leaving you in a constant loop of uninstalling and reinstalling.
