In macOS Sequoia, Apple has added one other stumbling block to launching software program that has not gone by way of Apple’s baseline vetting course of for apps. Usually, this generally is a good factor, stopping naive customers from unintentionally putting in malware or privacy-invading software program. Nevertheless, for customers who depend on software program created by individuals who don’t work inside the strains painted by Apple and its App Retailer, right here’s what that you must know.
The Gatekeeper function in macOS is one thing you by no means see referred to as by that title. It’s designed to make sure that solely sure apps can run in your Mac, though macOS can execute any appropriately constructed software program for the platform. The one seen management is in System Settings > Privateness & Safety > Safety, the place you may select considered one of two choices from the “Allow applications from” menu: App Retailer, or App Retailer & Identified Builders. (See: The best way to open a Mac app from an unidentified developer).
There’s a 3rd class that Apple eradicated from this listing in macOS years in the past. (The menu used to seem as radio buttons in a distinct System Preferences pane.) These are apps the place the programmer selected to not pay the annual price for an Apple Developer account, or they’ve such an account however didn’t run the app by way of a vetting system Apple makes use of that’s an enormous step under the App Retailer’s overview course of.
When a developer submits an app to an App Retailer, Apple makes use of a mixture of automated and human overview to make sure that the app doesn’t comprise malware or software program code from third events that it doesn’t enable and that it roughly does what it says it does with out being deceptive. That course of is stuffed with human error and inconsistencies, however it has principally led to secure apps within the App Retailer, even when some are scammy of their pricing intent or deceptive about how helpful they’re.
Mac builders can select, as a substitute, to have Apple notarize and signal an app. Notarization is the corporate’s course of for checking for malware and for software program libraries (bundles of code shared amongst apps) that might be swapped out for different elements. If the app passes these automated checks, Apple makes use of a cryptographic course of to signal it, which ensures the app can’t launch if it’s been modified since passing these checks. (Notarization was an optionally available step at one level, made necessary in 2020; all apps signed since then have additionally been notarized.)
Some builders want to not interact in that step. They don’t need to pay the annual developer price, use elements that Apple doesn’t notarize for macOS, or don’t need Apple to have a say-so on whether or not their software program can run. These unsigned apps can nonetheless run in your Mac. I’ve discovered fewer over time, however they nonetheless exist and usually come from specialised educational and analysis fields.

I urge you to proceed to train a excessive degree of vigilance round unsigned apps as you totally depend on the developer to guard your safety and privateness. Nevertheless, few apps like which have sufficient attain that any malware practitioner would have an curiosity in exploiting a weak spot.
