After almost three months of testing by the developers and users of the public beta program, the guys from Cupertino have released the final version of macOS Mojave, an operating system that is not compatible with the same computers as the previous version, since which is only compatible with equipment manufactured from 2012.
For three years, Apple in its effort to improve the security of its desktop operating system, and thus force users to make use of the Mac App Store, does not natively allow the installation of third-party applications, by eliminating that option of the Security and Privacy options. Fortunately, via a simple Terminal command, we can show that option again.
With the release of macOS Sierra, Apple It only allowed us to install applications available in the Mac App Store or from authorized developers. The Anywhere option was gone. If you want to be able to install any application from outside the Mac App Store and that has not been created by authorized developers, we must proceed as follows.

- First we must access Terminal, through the Launcher or by pressing the Command + Space key and typing in the search box Terminal.
- Next, we must enter the following code: sudo spctl --master-disable
- Please note: Before master, there are two hyphens (-), no one. Next, we write the password of our team.
- Next, we must restart the Finder for the changes to take effect, through the command Killall Finder
- Then we head up System preferences.
- Click on Security and Privacy.
- Finally inside the option Allow apps downloaded from, a new option should appear Anywhere, option that we must select to install third-party applications downloaded from the Internet, even if the developer is not authorized by Apple as trustworthy.
If the Anywhere option does not appearYou just have to do a test by installing an application that you could not previously. At that moment, macOS will ask us if we want to install it, giving us the option to do so (an option that did not appear before) or, on the contrary, cancel the installation.
