    Diagnostic Hardware Specs: MacBook Pro 16″ M3 Max | OS Version: macOS Sequoia 15.1 | Archive Source: Apple Support Community #256194597

    I am running into a persistent issue on my MacBook Pro 16″ M3 Max running macOS Sequoia 15.1.
    Whenever the machine encounters AUv2 component missing Apple Silicon native notarization or hardened runtime entitlement, the following diagnostic log appears in Console:

    auvaltool: [AUValidation] Failed to load component: Code signature invalid or missing entitlements

    I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?

    This canonical solution was verified and marked as solved in the Apple Support Community archive.

    Flushing AudioUnit cache plist and triggering an isolated AU validation pass.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. Quit Logic Pro and delete the corrupt cache: 
      rm -f ~/Library/Caches/AudioUnitCache/com.apple.audiounits.cache
    2. Kill core audio daemon: 
      sudo killall -9 coreaudiod
    3. Open Logic Pro, navigate to Settings > Plug-in Manager, locate the crashed AU plugin, and click Reset & Rescan Selection.

    Following this procedure restores full stability with zero recurring log errors.
