Updated November 26th, 2019. Sometimes you download a Mac app and it won’t open. You get a dialog box that says the app can’t be opened because it’s from “an unidentified developer” and your security settings won’t allow it. MacOS Sierra changed the way your Mac handles applications from unidentified developers. It's now stricter with installing such apps than previous versions of OS X, but there are ways to get.
How to download apps that aren’t on the App Store or come from unidentified developers. There are two main ways to give your Mac access to a broader range of apps: Set your Mac to allow you to open apps that aren’t from the App Store; Set your Mac to allow apps from unidentified developers.
If you are trying to launch an application, which is not installed from App Store and the developer of the application is unidentified, then you may get an alert saying “[App name] can’t be opened because it is from an unidentified developer”. Mac why keyboard shortcuts only works in some apps using. This security feature in Mac OS X is called GateKeeper, which by default blocks all the applications which are not from a verified source or from App Store.
Fix “can’t be open because it is from an unidentified developer” for a particular application without altering security settings
If you want to add exception for a particular application without changing GateKeeper’s security settings, follow the steps below.
Mac quit application. 1. Here we have tried to launch “Open Office” and we got below error.
“OpenOffice” can’t be opened because it is from an unidentified developer
“OpenOffice” can’t be opened because it is from an unidentified developer
2. To fix this, navigate to System Preferences > Security & Privacy.
3. There you can see below message “OpenOffice” was blocked from opening because it is not from an identified developer. Click on “Open Anyway” button, followed by “Open” in pop up. That’s it.
Now on you will able to launch this particular application (Here it’s OpenOffice) without any issue. Mac OS X will remember this exception for this particular application. But as default security settings of GateKeeper has not been altered, you will have to perform the same steps again if you get this issue for another application with unidentified developer.
You can also do the same by control-clicking (right click) on the particular application logo and then select “Open” option followed by again “Open” option to launch it anyway.
Permanent fix for all applications from unidentified developer
For doing this you have to alter security settings in your Mac OS X, which is not a good idea as it will make your Mac less secure. Instead of doing this it’s alway recommended to allow individual applications as stated above. For permanent fix for all applications from unidentified developer follow the steps below:
1. Go to System Preferences > Security & Privacy. Click the lock to make changes and enter your account password to verify.
2. Now set the radio button to Anywhere followed by Allow from Anywhere. This settings will be reset automatically if you don’t use this feature for 30 days. https://tysqpl.weebly.com/blog/macos-apps-used-most.
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.
Mac maximize window app. After changing my settings, I was able to open and run RStudio with no problem.
