Apple has a built-in way to protect you from opening up potentially malicious apps on your computer in Mac OS X. This setting, named Gatekeeper, will never stop you from installing apps from the Mac App Store, but it can help prevent helps from being installed that are not a part of the Mac App Store. However, if you get a security warning and still want to install the app, here is how to do it.

Choosing Your Gatekeeper Options
Firstly, you can permit apps from unidentified developers on an app-by-app-basis, by temporarily overriding your Mac’s security settings. This encourages you to think critically about each application before launching it, and is therefore one of the safest ways to use apps from unidentified developers. Mac OS X defaults to preventing applications from unidentified developers or sources from being launched. You’ll discover the message in Mac OS when you try to launch a Mac app that didn’t come from a verified source or from the Mac App Store, and you’ll get an alert dialog that says “App name can’t be opened because it is from an. If and when you try to open a quarantined app, Gatekeeper checks it for known malware, validates the developer signature to make sure it hasn't been tampered with, makes sure it's allowed to run, for example matches your settings for App Store apps and/or known developer apps, and then double checks with you that you really want to run the app. Setting your Mac to open apps from unidentified developers. If you want your Mac to allow apps from unidentified developers, you’ll have to follow a few additional steps. Firstly, try to open the unrecognized application. You’ll see a notification that it can’t be opened. Then, follow the instructions: Open System Preferences.
Select Open from the pop-up menu; You’ll be asked to confirm that you want to open it, since it’s flagged as being from an “unidentified developer.” If you’re sure it’s okay, go ahead and click the Open button. The application will immediately open – and it will also open on subsequent launches without any warnings.

Mac App Store & Trusted Developers

Apps from Anywhere
The last option, 'Anywhere,' removes Gatekeeper's blocking capabilities on your Mac, letting you install and open any app off the internet, including Automator apps made by individuals. Sometimes Apps that fall in this category contain malware, We do not recommend using this option and instead recommend using the 'identified (trusted) developers' option above and okay installation of apps missing a Developer ID on a case-by-case basis.
Trusting Apps on a Case-by-Case Basis
If you have the 'Mac App Store and identified (trusted) developers' option selected, then when you download an app without a Developer ID and try to open it, you'll get the following warning.
- 'App Name' can't be opened because it is from an unidentified developer
To bypass this restriction, select 'OK' on the popup to close it, then go into the 'Security & Privacy' section in your 'System Preferences.' Below the Gatekeeper options in the 'General' tab, you will see the app that was blocked from opening. To trust it, select 'Open Anyway'.
An Even Shorter Way to Open Them
Download From Unidentified Developer Mac
If you do not want to go into Systems Preferences to open an app for the first time as shown above, then Control+Click on the app in the Finder, then select 'Open.' You will see a new popup asking if you're sure you want to run the app on your Mac. Just hit 'Open' again and the App will launch as expected.
