The safest place to get apps for your Mac is the App Store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered. If there’s ever a problem with an app, Apple can quickly remove it from the store.
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. By default, macOS Catalina also requires software to be notarized, so you can be confident that the software you run on your Mac doesn't contain known malware. Before opening downloaded software for the first time, macOS requests your approval to make sure you aren’t misled into running software you didn’t expect.
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy.
Sep 27, 2016 Gatekeeper in MacOS is now stricter than ever, defaulting to only allow options for apps downloaded from either the App Store or the App Store and identified developers. Advanced Mac users may wish to allow a third option, which is the ability to open and allow apps downloaded from anywhere in MacOS Catalina, macOS Sierra, macOS High Sierra.

By default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. For additional security, you can chose to allow only apps from the App Store.
In System Preferences, click Security & Privacy, then click General. Click the lock and enter your password to make changes. Select App Store under the header “Allow apps downloaded from.”

Open a developer-signed or notarized app
If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch a new app, your Mac asks if you’re sure you want to open it.
An app that has been notarized by Apple indicates that Apple checked it for malicious software and none was detected:
Prior to macOS Catalina, opening an app that hasn't been notarized shows a yellow warning icon and asks if you're sure you want to open it:
If you see a warning message and can’t install an app
If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app can't be opened because it was not downloaded from the App Store.*
If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t signed by an identified developer or—in macOS Catalina—notarized by Apple, you also see a warning that the app cannot be opened.
If you see this warning, it means that the app was not notarized, and Apple could not scan the app for known malicious software.
You may want to look for an updated version of the app in the App Store or look for an alternative app.
If macOS detects a malicious app
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
How to open an app that hasn’t been notarized or is from an unidentified developer
Running software that hasn’t been signed and notarized may expose your computer and personal information to malware that can harm your Mac or compromise your privacy. If you’re certain that an app you want to install is from a trustworthy source and hasn’t been tampered with, you can temporarily override your Mac security settings to open it.
In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.
The warning prompt reappears, and you can click Open.*
The app is now saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorized app.
*If you're prompted to open Finder: control-click the app in Finder, choose Open from the menu, and then click Open in the dialog that appears. Enter your admin name and password to open the app.
Over the past two years, macOS Mojave and Catalina gently evolved to aid developers in creating universal apps for Macs and iPads, including Apple internal and then third-party use of the cross-platform Catalyst framework. Today, Apple is taking another major step with the release of macOS Big Sur, which will be the first version to support Apple-developed ARM processors for Macs.

The latest update continues Apple’s use of California landmarks to brand macOS releases. Big Sur is a large stretch of intentionally undeveloped coastline in central California, notable for its access to forests, beaches, and numerous picturesque locales that haven’t been damaged by human development. During its presentation, Apple showed off an About screen indicating that this is macOS 11 — the first step beyond the numerous “Mac OS X” or macOS 10 releases that preceded it. Though Apple’s initial developer download for the release lists it as “macOS Beta 10.16,” and the first Big Sur beta reports itself to apps as macOS 10.16, the “About this Mac” screen and Apple have confirmed that the long-awaited version number 11 is correct.
Macos Developer Setup
Apple has redesigned the macOS user interface significantly, borrowing many iOS and iPadOS design cues to create multi-pane and glyph consistency across platforms. While macOS icons have been updated to bring back some 3D shadowing and depth — removed from Apple products years ago in a post-Steve Jobs purge — most of the other elements, such as a revised Control Center with flat-shaded controls, now look substantially like similar features on the iPhone or iPad.
