Mac App Store and approved developers:Compared with the previous option, the condition of this option is a little looser. If an application cannot be listed on the Mac App Store, but the developer has a digital signature and certificate issued by Apple and built it into the application, the application can also be opened with Gatekeeper approval. 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.
I recently purchased Mac book air and got a free upgrade to OS X mountain lion which added some new security feature, which will prevent installing of 3rd party apps. I was trying to install VLC and MAMP app and everytime I got this error on my Mac: “App Can’t be opened because it is from an unidentified developer.” If you are running OS X mountain Lion 10.8+, you might be getting the same error. Here is a screenshot of this error:
Follow the below mentioned guide to solve this issue.

If you are installing app via official App store, you will not be facing any such issue and even if you are download app from few sites, you will not be facing any issue. But for most of other mac apps, this warning message is basically a security measure and you can quickly fix it by making some changes in security settings of your mac.
Go to System preferance and click on Security and privacy. Under general tab, below you will see a golden lock icon, click on it to make changes. Once you disable lock, you will be able to make changes in all greyed option.
Simply select the option under ” Allow applications downloaded from” and select the option which says “Anywhere”, it will give you another prompt and select the option “allow from anywhere”. Enable the lock again and now you will be able to install any 3rd party applications on your Mac. Below is a screenshot to understand the process:
Though it’s a good feature but Apple should work on increasing the number of apps on Mac app store. As right now there are very few apps and I’m sure many of you might not live without 3rd party mac apps.
I hope this quick fix will help you installing any kind of apps on your Mac and if you still have trouble installing 3rd party apps, do let me know and I will find an answer.
