If you are new to MAC OS, you may have seen the warning message “App can’t be opened because it is from an unidentified developer“. The “App” can be any software which you are trying to install outside Apple App Store. OS X feature called Gatekeeper is the reason why you are seeing these kinds of warning messages. The job of Gatekeeper is to protect your Mac from apps which are downloaded and installed from places other than App Store.
As you know, Apple prefers downloading apps from Apple store in its all products. Sometimes developers won’t publish apps on app store and ask users to download from their website or from a third-party app store. In most cases, this is to bypass Apple’s strict security checks. Finding this as a threat, Apple decided to implement the new feature called Gatekeeper, to protect Mac from malicious apps. Anyway, all latest Mac OS has this feature and you need to do something extra for installing apps outside Apple Store on your Macbook.
Here in this tutorial, we are showing how to install software which is downloaded outside of Apple Store.
Step by Step Instruction to solve “App can’t be opened because it is from an unidentified developer” on MAC
Step 1:- Open System Preferences. You can open it from the quick launcher or by clicking the –> System Preferences.
Step 2:- Now click on Security & Privacy icon.
Step 3:- There will be four different menu buttons. Among them, click on the “General” menu. There you can see the option to choose “Allow apps downloaded from” either App Store or from both App Store and identified developers.
Just below to that, you will see the app which you got the warning message. For me, I was trying to install Sodaplayer (App to watch AceStream in Mac) and there was a message shown as “Soda Player Was blocked from opening because it is not from an identified developer.”
Just right to that message, you will see “Open Anyway” option. Click on that to continue.

Step 5:- After that, you can see the option to Open the app. Click on Open to use the app.
After finishing the installation, you will see a folder in your desktop with the name of the newly installed software. Just Double click on that folder to see the launcher icon of the installed app. Double click on the icon to start using the app. Also if you want, you can drag the icon to application folder and you can access the app from applications.
