Can’t Be Opened Because Apple Cannot Check It for Malicious Software: 7 Astonishing Fixes

If you’re a Mac user, you’ve likely encountered the frustrating message that says, “can’t be opened because Apple cannot check it for malicious software.” This pop-up often occurs when trying to open third-party apps downloaded outside of the Mac App Store. Due to macOS’s stringent security measures, the system blocks any software it cannot verify as safe, ensuring your computer remains protected. However, encountering this message doesn’t necessarily mean the software is harmful. In this guide, we’ll explore seven reliable fixes to bypass this error and keep your device secure. We’ll also cover preventive measures and provide tips on how to check for malware on your Mac.

What Does “Can’t Be Opened Because Apple Cannot Check It for Malicious Software. Mean?

This error stems from Apple’s Gatekeeper, a security feature integrated into macOS. Gatekeeper is designed to protect users by verifying apps for malware and ensuring they come from trusted developers. When you see the “can’t be opened because Apple cannot check it for malicious software. warning, it means the software you’re attempting to open lacks a valid developer signature. Essentially, macOS can’t confirm whether the app is safe to use. This error message might be annoying, but it’s an indication that Apple prioritizes your system’s security.

Why Does This Error Occur?

Understanding why this error appears can help you decide how to proceed. Here are some common reasons for the “can’t be opened because Apple cannot check it for malicious software. message:

• App Not Signed by a Verified Developer: Apple mandates that developers sign their apps with an Apple-issued certificate. Unsigned or improperly signed apps will trigger this error.
• Software Not in the Mac App Store: Applications downloaded outside the official Mac App Store may not be verified by Apple.
• Outdated macOS Version: Older macOS versions may have stricter security settings that block software installations.
• Newer macOS Security Enhancements: With each macOS update, Apple tightens security protocols, possibly blocking apps that previously worked fine.

How to Fix the “Can’t Be Opened Because Apple Cannot Check It for Malicious Software. Error

Here are seven effective methods to bypass this error while ensuring your Mac remains safe.

1. Right-Click and Open Anyway

One of the simplest ways to get past this error is to use the right-click method:

• Locate the application in your Downloads or Applications folder.
• Right-click the app icon and select Open.
• A warning dialog box will appear with the option to Open. Click it to bypass the security alert.

This manual override allows you to open the app without changing your overall security settings.

2. Go to System Preferences and Allow Access

You can also change your security preferences directly:

• Open System Preferences from the Apple menu.
• Go to Security & Privacy.
• In the General tab, you’ll see a message that says “[App Name] was blocked because it is not from an identified developer.”
• Click the Open Anyway button to allow the app to run.

Remember to use this option judiciously, only for trusted software.

3. Temporarily Disable Gatekeeper

For a more permanent solution, you can disable Gatekeeper, but this should be done with caution:

• Open Terminal from the Utilities folder.
• Type the command: sudo spctl --master-disable.
• Enter your administrator password and press Enter.
• Go to System Preferences > Security & Privacy. You’ll now see an option to allow apps downloaded from Anywhere.
• Change this setting back to App Store and identified developers after opening the app to ensure your system’s security.

How to Check for Malware on iPhone

Although the can’t be opened because Apple cannot check it for malicious software. message pertains mainly to macOS, it’s also crucial to ensure your iPhone is malware-free. iPhones are generally secure, but if you suspect an issue, follow these steps:

1. Keep iOS Updated: Apple releases regular security updates to address vulnerabilities. Make sure your iPhone is running the latest version of iOS.
2. Review App Permissions: Go to Settings > Privacy and check which apps have access to sensitive data like your location, contacts, and photos.
3. Use a Trusted Antivirus App: Download a reputable antivirus app from the App Store if you want an added layer of protection.
4. Factory Reset (If Needed): If you suspect severe malware, a factory reset may be necessary. Remember to back up your data first.

4. Update macOS to the Latest Version

Outdated macOS versions can cause compatibility and security issues. Updating to the latest version can solve the “can’t be opened because Apple cannot check it for malicious software. problem:

• Go to the Apple menu and select System Preferences.
• Click on Software Update and install any available updates.

Newer macOS versions may have better app verification and security settings, reducing the likelihood of encountering this error.

5. Manually Allow the App in Security Settings

If the previous steps didn’t work, you can manually authorize the app:

• Try to open the app. After receiving the warning, go to System Preferences > Security & Privacy.
• Look for the blocked app message and click Open Anyway.

6. Re-Download the App from a Trusted Source

Sometimes the download itself is the problem. If you encounter the error, consider deleting the app and re-downloading it from the developer’s official website or another trusted source.

7. Use Terminal Commands to Bypass the Warning

For advanced users comfortable with Terminal, you can use commands to override security settings:

• Open Terminal.
• Type: sudo xattr -rd com.apple.quarantine /Applications/YourAppName.app.
• Replace YourAppName with the actual app’s name. This removes the quarantine attribute from the file, bypassing the security check.
