Apple Cannot Check It For Malicious Software [Fix]

Table of Contents

Let’s dive deep into the topic Apple cannot check it for malicious software. When attempting to open an application on your Mac, you may at times receive the error message “Apple cannot check for malicious software.” This error message is displayed when Apple’s Gatekeeper security feature cannot verify the app’s authenticity or safety. Gatekeeper is an in-built security feature that is designed to protect your device from malware. It does this by checking apps against a list of known safe apps. If an app is not on this list, Gatekeeper will prevent you from opening it.

Error message “Apple cannot check it for malicious software” can occur for a few reasons:

One possibility is that the app is not from the official App Store. This is a curated marketplace where Apple reviews all apps before they are made available for download. This means that apps from the App Store are less likely to contain malware.
Another possibility is that the app is from an unknown source. This means that you downloaded the app from a website or another source that is not known to Apple. Apps from unknown sources are more likely to contain malware.
Finally, the error message “Apple cannot check for malicious software” can also occur if the app has been corrupted. This can happen if the app was downloaded incorrectly or if it was damaged during installation.

Additionally, here are some other things to keep in mind:

This error message may also appear if you try to open an app that was created for an older version of macOS.
If you are certain that the app is safe, you can override the security settings on your device to open it. However, remember that you should only do this if you are absolutely sure that the app is safe.
If you are unsure whether an app is safe, it is best to avoid opening it.

To protect your device from malware, you should:

Only download apps from trusted sources, such as the App Store.
Keep your Mac’s software updated.
Use a malware scanner.
Be careful about what websites you visit and what links you click on.

If you trust the source of the app and are certain that your device will not face a security threat by the installation and use of the app, there are a few ways to override the inherent security features. Remember to use these ways only when you are sure that there will be no malware-related complications or issues.

Method 1: Utilizing Control Click Property

Instead of double-clicking on an app to open it as usual, right-click on it. Even with the security notification, this will let you select how to open the app. For this:

Look for the installer package of the app or the plugin that you want to open.
Right-click on it and select the ‘Open’ option.

Open the Apple menu and select the ‘System Preferences’ option.
Next, look for ‘Security & Privacy’ and select it.
In the ‘General’ tab, unlock the ability to change settings by clicking the yellow lock on the bottom-left of the window.
Enter your device password when prompted to and then hit Enter to unlock.
Just above the lock, look for the mention of the app that was blocked from being opened and select the ‘Open Anyway’ option.

Open Unidentified App From Security Privacy

Select ‘Open’ once again to confirm your choice.

Method 3: Opening Apps Using Terminal

Modifying the specified attribute of an app that doesn’t pass Gatekeeper’s checks allows you to install and run the app smoothly. Always perform this action only if you trust the source.

On the home screen, go to Finder and look for the Utilities Folder.
Find Terminal in the list and double-click to open it.
Enter the following command:

xattr -d com.apple.quarantine filepath

Replace the file path in this command with the actual path of the app. You can easily do this by dragging the location of the file and dropping it in the Terminal.
Enter your device password when prompted to and hit Enter.
Restart your device.
Now, you can open the app.

Method 4: Allow Apps Downloaded from Anywhere

Remember to use this option only if you fully trust the source of the app and more importantly, also remember to definitely switch the security back once installation is complete.

On the home screen, go to Finder and look for the Utilities Folder.
Find Terminal in the list and double-click to open it.
Enter the following command:

sudo spctl –master-disable

Enter your device password when prompted to and hit Enter.
Now, you can install the app by following the steps appearing on your screen.
Once installation is successful and the app is launched, go back to the Terminal to enable security. Do not forget this step or the future security of your device will be in danger.
Enter the following command:

sudo spct1 –master-enable
