Over the years, Apple has put its vast resources into making it's operating systems more secure for end-users. In macOS Catalina, the company has taken this to all-new levels by introducing beneficial security changes that make it even harder for miscreants to play havoc with our computers. However, because security is a tricky business, so-called improvements for some might not work for others. Specifically, Apple's decision to make Gatekeeper even more difficult crack is a significant step forward for everyday Mac users. For developers, perhaps not so much. Luckily, there's a workaround.
Mac OS X (10.8.x / 10.9.x / 10.10.x / 10.11.x) and macOS - Run Programs from Unidentified Developers This document describes how to enable installation/launch of applications if you encounter launch errors via. How to open apps from unidentified developers on macOS Sierra. So, now, you have to allow app downloads on an individual basis by confirming your permission when you try to open one. There is a way to get back to Gatekeeper's previous settings, which allow you to download apps from anywhere, by using a terminal trick, which we'll show you in. Oct 07, 2019 If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer and that it has not been altered.
Warning: This terminal trick disables important security aspects of Gatekeeper, which leaves your Mac vulnerable to malware. We highly recommend you reinable the default security settings if you chose to follow this guide at your own risk.
What is Gatekeeper?
Gatekeeper has been an essential part of macOS for years. As its name suggests, the tool has been designed to check recently downloaded apps for known malware and sends it to quarantine. In his June article, The Great Mac Balancing Act, Rene Ritchie explains:
Currently, when you download an app, whether it's off the Store or the Web or even from AirDrop, that app is quarantined. If and when you try to open a quarantined app, Gatekeeper checks it for known malware, validates the developer signature to make sure it hasn't been tampered with, makes sure it's allowed to run, for example matches your settings for App Store apps and/or known developer apps, and then double checks with you that you really want to run the app for the first time, that it's not trying to pull a fast one and autorun itself.
Mac Open Unidentified Developer
Until now, Gatekeeper didn't take the same approach with apps launched via Terminal. It also didn't check non-quarantined apps and files for malware. In other words, it checked an app only once for malware.
Significant changes have arrived with macOS Catalina.
Now, apps started through Terminal are also checked. These files get the same malware scan, signature check, and local security policy check. The difference: even on the first run, you only need to explicitly approve software launched in bundles, like a standard Mac app bundle, not for standalone executables or libraries.
With macOS Catalina, perhaps more significantly, Gatekeeper will also check non-quarantined apps and files for problems. Not just once or twice, but every time you run it. When your Mac detects a problem, it blocks the file, then sends you an alert.
If all this sounds fantastic to you, terrific. That's undoubtedly Apple's intent. However, some developers might view this differently and find the changes cumbersome, at best.
A Workaround
Even though Gatekeeper in macOS is now stricter than ever, there is a way around it -- including macOS Catalina's newest tools. The workaround makes it possible to download and use apps downloaded from anywhere on macOS Catalina and earlier versions without a check.

Many times we need to install apps which are not present on the Apple Mac OS X Store. In such cases we either download the app from external sources on the web. These apps prompt errors such as”app can’t be opened because it is from an unidentified developer” when we try to install them. In this tutorial we will show you two ways to Open & install Applications or Programs from Unidentified Developer in Mac OS X. This method has been tried & tested on Mountain Line, Mavericks, Yosemite as well as El Capitano too.

Pre-Requisites :
