Common Mistakes to Avoid
1. Downloading from Untrusted Sources
Reason: Downloading applications from websites or sources not verified by Apple can lead to this error because macOS cannot confirm the developer's legitimacy.
Solution: Download the application only from trusted and verified sources, such as the Mac App Store or the official developer's website.
2. Ignoring System Security Settings
Reason: Disabling or altering macOS's security settings, such as Gatekeeper, to allow apps from unidentified developers without fully understanding the risks can cause this error and expose your system to vulnerabilities.
Solution: Ensure your system security settings allow apps from identified developers or temporarily adjust settings to allow the specific app, then revert to stricter settings afterward.
FAQs
Why am I getting this error? What does 'developer cannot be verified' mean?
macOS has a security feature that prevents you from opening applications from unidentified developers. This error appears when the application's digital signature is missing, invalid, or from a developer not recognized by Apple. It's a security precaution to protect your Mac from potentially malicious software.
Is it safe to bypass the security warning and open the app anyway?
Generally, no. Opening an app from an unverified developer significantly increases the risk of malware infection. Unless you absolutely trust the source and understand the risks, it's best to avoid opening the application. If you need the application, consider seeking it from a trusted source like the developer's official website.
How do I permanently disable the security warning? Should I do this?
You can temporarily bypass the warning for a specific app, but permanently disabling security checks is strongly discouraged. It severely compromises your Mac's security and makes it vulnerable to malware. Instead of disabling security, find a verified alternative or contact the developer to get a properly signed version of the application.
