Excerpt of article text...

It's midnight. You're sleeping soundly because your new Mac application has been launched to great success and people are downloading it like mad from your website. But when you get up in the morning, you're greeted by a disaster: hundreds of customers are complaining that the new app you've labored on for months is a virus! They claim that they get an ominous-sounding error message when they try to run your app (see Figure 1). The message says the app is from an "unidentified developer" and can't be launched. What is going on?

In short, your app has been blocked by a new security feature of Apple's latest operating system, Mountain Lion (10.8). You didn't notice it during development, because apps created on your computer are allowed to run—only apps downloaded from the Internet are blocked.

If you don't fix the issue, very few Mountain Lions users will bother with your app. While knowledgeable users will know how to bypass the security warning (right-clicking and choosing "Open" will offer a different dialog that at least allows the app to run—see Figure 2), most will not and you'll lose potential customers.
