Downloading apps from the Mac App Retailer can be a stable plan for guaranteeing the Mac runs solely protected software program. This is not all the time doable, although. Generally, an app is not obtainable from the Mac App Retailer, so it’s important to look elsewhere.
Savvy Web customers could have their methods of understanding whether or not a obtain is protected or not, comparable to by guaranteeing it is downloaded from an official supply just like the developer’s web site.

Gatekeeper is the system Apple makes use of in macOS that tries to guard the Mac from malware by limiting what can run. Relatively than permitting something to run, Gatekeeper acts as a digital bouncer, verifying the app earlier than executing it.
In essence, Gatekeeper verifies a downloaded app earlier than operating it for the primary time. As a part of this, it ensures the app has both been sourced from the Mac App Retailer or, if acquired from the broader Web, that it has been signed by a legitimate Developer ID and notarized by Apple.
The Developer ID certificates is issued by Apple and offered to a developer as an indicator that they’re a trusted get together and the creator of an app. Nevertheless, that is not all an app must move the Gatekeeper.
Since macOS 10.15, all software program distributed with a Developer ID have to be notarized. The developer should present the app to Apple’s automated notary service that scans the software program and performs different checks to make sure it is protected to run.
A notarized app with a legitimate Developer ID and a Gatekeeper-readable ticket is trusted by macOS and may run with none points.

In common use, this is not a giant deal. The place it turns into an issue is in case you’re utilizing software program that hasn’t been notarized in any respect.
Whereas sometimes not signal, this may be fully harmless, comparable to if a developer hasn’t up to date an app in a number of years. If it is sufficiently old, it will not have been up to date since notarization grew to become required for Developer ID-associated apps.
Often, Gatekeeper does the precise factor and prevents you from operating the app. Nevertheless, if it is an app you recognize is protected, you’ll have to instruct Gatekeeper to let it run.
