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.

View the app security settings on your Mac

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 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.

  • Check it is a trusted software using Gatekeeper technology.
  • Verify the identity of the developer using Developer ID in the installer package.
  • macOS Catalina also needs the developer to notarize the apps for trustworthy.

Most of the third-party apps will fail at the identification or notarization part leading to prevention of usage on Mac. In most case, you may be using it for long time, and it is not quite easy to inform the developer to update the app.

Third-party Apps Errors in Mac

Mac settings allow you to choose only install apps from App Store or allow apps from identified developers. You will get different error depending upon this setting. When you allow third-party apps in settings, Mac will not stop installing or updating the apps without developer ID and notarization. It will only stop when you open the installed app. This will make an app unusable with an update in the latest macOS. You will get the error like below mentioning, “App can’t be opened because Apple cannot check it for malicious software”.
