What is ‘Cannot check for malicious software’ issue in Apple
“Cannot check for malicious software” is a problem that often happens on Apple devices when Gatekeeper, the built-in security tool, has trouble verifying the digital signatures of apps. Gatekeeper is a very important part of macOS that makes sure that only safe and authorised software gets installed. If this mistake shows up, it means there may be a problem with the verification process.

This glitch could be because of a problem with the developer’s certificate or with the internet link. If you are having this issue, the first thing you should do is make sure your internet link is strong. Should the issue still happen, it is suggested that you try to download or run the software once more. It can also be helpful to check for changes and make sure the developer’s certificate is real.
Causes for ‘Cannot check for malicious software’ issue in Apple
- Outdated Software: When your Apple device’s operating system or security software is not up-to-date, it may struggle to effectively check for malicious software.

- Server Overload: Apple’s security servers might experience high traffic or be temporarily unavailable. This can result in your device being unable to check for malicious software at that moment.
- Device Compatibility: Older devices or those with lower system specifications may face challenges when attempting to perform thorough security checks, leading to the error message.
- Permission Restrictions: If the necessary permissions for security checks are restricted, your device may struggle to assess and verify the presence of malicious software.
