Introduction: what is macOS and what are its features?
MacOS is a computer operating system developed and marketed by Apple Inc. It is the primary operating system for Apple’s Mac family of computers. Within the market of desktop, laptop and home computers, macOS is the second most widely used desktop OS after Microsoft Windows.
The latest version of macOS is Catalina, which released on October 7, 2019. It succeeded Mojave, which released on September 24, 2018.
macOS is a Unix-like operating system based on the XNU kernel and other free software projects such as Darwin. Its graphical user interface (GUI) uses a desktop metaphor; the Finder presents a finder window that displays the contents of folders in hierarchical views similar to those used by many file managers though with significant enhancements such as support for metadata and icon previews.
Why Does My Mac Say “MacOS Cannot Verify That This App Is Free from Malware”?
If you’re trying to open an app on your Mac and you get a message that says “macOS cannot verify that this app is free from malware,” it means that the app has not been notarized by Apple. This doesn’t necessarily mean that the app is harmful, but it does mean that Apple has not checked it for known malicious code.
You can still open the app by clicking “OK” in the message, but you should only do this if you trust the app and its developer. If you’re not sure, you can check to see if the developer is verified by Apple by looking for their name in the “Developer ID” section of Apple’s developer website.
Is It Safe to Open an App macOS Cannot Verify?
When you try to open an app that is not registered with Apple by an identified developer, you get a warning dialog. This is because such apps can potentially harm your Mac. The message says that macOS cannot verify that this app is free from malware.
So, is it safe to open an app macOS cannot verify?
The short answer is no. You should not open an app that macOS cannot verify. It is always better to be safe than sorry.
The longer answer is that it depends on the app and your level of risk tolerance. If you are trying to open an app from a well-known and trusted developer, then it is probably safe to do so. However, if you are trying to open an app from an unknown or untrustworthy source, then it is best to err on the side of caution and not do so.
Ultimately, the decision of whether or not to open an app macOS cannot verify is up to you. If you are feeling unsure or unsafe about doing so, then it is probably best not to.
How to fix “macOS cannot verify that this app is free from Malware”
If you see a message saying “macOS cannot verify that this app is free from malware,” it means that the app has not been notarized by Apple.
This doesn’t necessarily mean that the app is malicious, but it does mean that it hasn’t been reviewed by Apple’s security team.
You can fix this error by following these steps:
- Right-click (or Control-click) on the app icon and select “Open.”
- A dialog box will appear warning you that the app is from an unidentified developer and asking if you are sure you want to open it.
- Click “Open.”
- The app will launch and you can use it as usual.
How to Check for Malware
If you see a warning that “macOS cannot verify that this app is free from malware,” it means that the app has not been notarized by Apple. Notarization is a process that Apple uses to verify that an app is free from malware.
If you’re sure that the app is from a trustworthy source and that you want to run it, you can override your security settings to allow it to run.
To do this, open the Security & Privacy panel in System Preferences and click the button labeled “Allow” next to the message.
You should only override your security settings if you’re sure that the app is safe. Once you’ve allowed an app to run, you can re-enable security settings by clicking the button labeled “Block.”
Why can’t some Mac apps be opened or verified?
When you try to open a Mac app that didn’t come from the App Store or was not created by an identified developer, you get a warning.
This message means that the app hasn’t been reviewed by Apple and might contain malicious software.
To open the app anyway, in the Finder, Control-click or right-click the app icon. Then, choose Open from the pop-up menu.
In macOS Catalina and later, additional protections apply to apps that are not notarized or are not signed. These protections apply even if you have Allow apps downloaded from anywhere in Security & Privacy preferences. If you try to open an app that isn’t notarized or signed, and it wasn’t downloaded from the App Store, you get a more definitive warning message.

How to open an app from an unverified developer
