I downloaded an application from AyumaxSoft, but it won't open on my Mac. What should I do?

This is a normal security behavior on macOS called “Gatekeeper.” Our applications are safe but may not be code-signed with Apple’s developer certificate, which triggers macOS security protection.

Solution Steps:

  • When you first try to open the app, you’ll see a message like:

“[App Name] cannot be opened because it is from an unidentified developer”

  • OR “[App Name] cannot be opened because Apple cannot check it for malicious software”

  • To safely open the application:

Go to System Settings (or System Preferences on older macOS)

  • Click Privacy & Security

  • Scroll down to the Security section

  • You should see a message about the blocked app with an “Open Anyway” button

  • Click “Open Anyway”

  • Confirm by clicking “Open” in the dialog that appears

  • Alternative method:

Right-click (or Control+click) on the application

  • Select “Open” from the context menu

  • Click “Open” in the security dialog

Why does this happen?

  • This is NOT a virus or malware issue

  • macOS protects users by blocking unsigned applications by default

  • AyumaxSoft applications are safe and tested

  • This is Apple’s standard security feature called “Gatekeeper”

  • Once you approve the app, it will open normally in the future

Important Notes:

  • ✅ This process is completely normal and safe

  • ✅ You only need to do this once per application

  • ✅ After approval, the app will launch normally

  • ✅ This affects many legitimate applications from independent developers
