What Does the Warning Mean?

When macOS shows the message, it means the app you're trying to open hasn’t passed Apple’s notarization process—a scan Apple performs to check for known malware and confirm the app’s integrity. Apps from unidentified developers or older apps often trigger this warning.

Why Apple Issues This Warning

Apple prioritizes user safety by ensuring apps are vetted before installation. If an app lacks this notarization, macOS assumes it could be risky. Even apps from known developers can show this message if they haven't been submitted to Apple for review.

Should You Open the App Anyway?

Generally, no. Overriding security settings is one of the most common ways Macs become infected with malware. If you’re unsure about the app’s origin or authenticity, it’s best to avoid it. Instead, look for an alternative in the Mac App Store or from a verified developer.

How to Manually Override macOS Security Settings

If you trust the source and decide to proceed, follow these steps:

1. Go to Apple Menu > System Settings > Privacy & Security
2. Scroll to the Security section and locate the blocked app
3. Click Open Anyway
4. Enter your login password and confirm

This creates an exception so the app can be opened like any other authorized software in the future.

Why This Matters

Apple’s warning is part of a broader effort to reduce malware infections on macOS. While it might seem inconvenient, it helps prevent malicious apps from gaining access to your system, your files, and your personal data.

FAQs

What is Apple’s notarization process?

It’s a security measure where Apple scans apps for malware and code-signing issues. Notarized apps are less likely to harm your Mac.

Is it safe to ignore the malware warning on Mac?

No, unless you are 100% certain of the source. Ignoring the warning may expose your system to threats.

What if the app I need isn’t in the Mac App Store?

Try to download it from the official developer’s website. Always verify the developer and avoid unknown third-party sources.
