How to Install and Run Apps on Mac That Are Not From the Mac App Store
Mac added a new feature Gatekeeper since OS X 10.8 Mountain Lion, which enforces code signing and verifies downloaded applications before allowing them to run, thereby reducing the likelihood of inadvertently executing malware. But it also implies that it only allows apps from the App Store or trusted developers to be installed. If you download special Mac software from the Internet, the system will automatically block it. What if you want to download an app which does not come from the App Store? Here we will show you how to install and run apps that are not from the Mac App Store.
1. The operating system before Sierra
Before the Sierra, Mac provides three options to allow the installation source and you can choose one as settings on your own condition. The steps to set it are as follows:
1. Open System Preference.
2. Go to Security & Privacy.
3. Select the General.
4. There are three options for Allow apps downloaded from:
●Mac App Store
●Mac App Store and identified developers
5. Choose Anywhere to allow apps downloaded that are not from the Mac App Store. (Click the lock icon in the lower-left corner and enter an administrative username and password if needed)
2. The operating system after Sierra
If your system is after Sierra, then the option "Anywhere" will be hidden by default. There are only two options for Allow apps downloaded from. So it's gonna take a bit effort to find out the "Anywhere" option in order to install and run apps that are not from the Mac App Store.
Here is the method of finding out the Anywhere option.
1. Open Terminal. (try Command + Space then search Terminal if you don't know where to open it)
2. Input "sudo spctl --master-disable" then hit Enter.
3. Enter the password then hit Enter.
4. Back to System Preference → Security & Privacy → General.
5. Then you will see the "Anywhere" option is available.
6. Choose Anywhere to allow apps downloaded that are not from the Mac App Store. (Click the lock icon in the lower-left corner and enter an administrative username and password if needed)
