Opening apps from unidentified developers: Staying Safe. Although there are countless perfectly legitimate apps released by unidentified developers, you are more likely to encounter malware when downloading this kind of software, compared to applications downloaded from the App Store, or apps released by identified developers. If you do decide to permit apps from unidentified developers, then. Basically, I used the native Safari.app web browser to download a third party application and I want to run / open it from the comfort of my bash shell / Terminal.app CLI; despite the following error. Since OSX Lion, Apple’s mac operating system includes a security tool named Gatekeeper. This feature prevents downloads of software and apps from unidentified developers. Gatekeeper assumes the app is trouble when the app you want to download is not signed with Apple. And it does not allow that app onto your mac computer.

Introduction: How to Open Third-Party Apps From Unidentified Developers in Mac OS X Yosemite, Mountain Lion, and Mavericks

In order to protect you from malicious apps on your computer in Mac OS X Lion, Mountain Lion, Mavericks, and Yosemite, Apple has built in a setting you need to know about. The setting, called Gatekeeper, allows apps installed directly from the Mac App Store, but it prevents installation of apps from anywhere else. I wanted to download RStudio and was able to download, but not open because of Gatekeeper. I was positive I trusted the developer, even though Apple does not, so I decided to change my settings to allow it. This is how I did it and how you can do it too from any app developer that you trust.

Step 1: Open Settings to Install Unidentified App You Trust

In this case, I want to open an app that I download from the internet, RStudio, but because Apple does not trust this developer, I need to change my settings. First thing I do is determine this is an app developer I trust. Then, I open settings and click the 'Security and Privacy' icon.

Step 2: Click on General and Unlock

After you click on the General button to the top left of the security window, you will see a portion that is locked called, 'allow apps downloaded from.' You want to unlock this portion so you will need to click on the lock icon on the bottom left corner of the privacy and security window. You will be prompted to enter your password.

Step 3: Click to Allow From Anywhere, Open Your App

Click the option 'Anywhere,' that removes Gatekeeper's blocking capabilities on your Mac, allowing you to download and open any app of the internet from an app developer you trust. I recommend only downloading from sources you trust so you don't wind up with an app downloaded with malware backed in.

After changing my settings, I was able to open and run RStudio with no problem.
