If you download and install apps from the Cyberspace or direct from a developer, macOS continues to protect your Mac. When you install Mac apps, plug-ins and installer packages from exterior the App Store, macOS checks the Programmer ID signature to verify that the software is from an identified developer and that information technology has non been altered. By default, macOS Catalina and later also requires software to be notarised, so you can be confident that the software you lot run on your Mac doesn't comprise 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.

Open a programmer-signed or notarised app
If your Mac is ready to allow apps from the App Store and identified developers, the kickoff fourth dimension that you launch a new app, your Mac volition ask if yous're sure you desire to open it.
An app that has been notarised past Apple indicates that Apple checked information technology for malicious software and none was detected.

If yous see this alarm, it ways that the app was not notarised, and Apple tree could not scan the app for known malicious software.
You may want to wait for an updated version of the app in the App Shop or await for an alternative app.
If macOS detects a malicious app
If macOS detects that software has malicious content or its authorisation has been revoked for any reason, your Mac will notify you that the app will damage your computer. You should move this app to the Trash and cheque "Study malware to Apple tree to protect other users".

Privacy protections
macOS has been designed to keep users and their data safe while respecting their privacy.
Gatekeeper performs online checks to verify whether an app contains known malware and whether the developer'due south signing certificate is revoked. We have never combined data from these checks with information about Apple users or their devices. Nosotros practice not employ data from these checks to learn what individual users are launching or running on their devices.
Notarisation checks whether the app contains known malware using an encrypted connection that is resilient to server failures.
These security checks have never included the user's Apple ID or the identity of their device. To further protect privacy, we accept stopped logging IP addresses associated with Developer ID certificate checks, and we will ensure that any collected IP addresses are removed from logs.
In improver, over the next twelvemonth, we will introduce several changes to our security checks:
- A new encrypted protocol for Programmer ID certificate revocation checks
- Strong protections against server failure
- A new preference for users to opt out of these security protections
