# Disable Library Validation Entitlement

A Boolean value that indicates whether the app loads arbitrary plug-ins or frameworks, without requiring code signing.

## Discussion

Discussion The Hardened Runtime enables library validation by default. This security-hardening feature prevents a program from loading frameworks, plug-ins, or libraries unless they’re either signed by Apple or signed with the same Team ID as the main executable. The macOS dynamic linker (dyld) provides a detailed error message when the system prevents code from loading due to library validation. Use the Disable Library Validation Entitlement if your program loads plug-ins that are signed by other third-party developers. To add this entitlement to your app, first enable the Hardened Runtime capability in Xcode, and then under Runtime Exceptions, select Disable Library Validation. important: Because library validation is such an important security-hardening feature, Gatekeeper runs extra security checks on programs that have it disabled. If your program is blocked by Gatekeeper, check whether you’ve unnecessarily disabled library validation.
