Allow To From Unidentified Developer Install Many Third

MacOS Sierra marks most unofficial apps as unsigned software, so youll need to perform this process to install many third-party apps or programs.

You can do this once per install, or you can disable this security feature altogether.

Note that you should only do this if you are certain you trust the publisher of the software.

This will prompt a pop-up with an error message that says Name cant be opened because it was not downloaded from the App Store.

Doing so will open your file and continue with the installation.

In order to allow all software installations, youll first need to restore an installation option that MacOS Sierra got rid of.

Doing so will restore the option you need in the Security Privacy menu.

Its below the Allow apps downloaded from heading near the bottom of the window.

Doing this will allow you to install software from unsigned developers without having to confirm from within this menu.

You should now be able to install your software as you usually would.

Look for the lock icon, enter your password, and click unlock to proceed with the necessary changes.

Open your software installation file.

Click OK. 3. Open the Apple menu.

Click Security Privacy.

Unlock the menu. 7.
