    Diagnostic Hardware Specs: MacBook Pro 14″ M1 Pro | OS Version: macOS Sequoia 15.1 | Archive Source: Apple Support Community #256187909

    I am running into a persistent issue on my MacBook Pro 14″ M1 Pro running macOS Sequoia 15.1.
    Whenever the machine encounters Corrupted Rosetta runtime translation cache after major macOS incremental delta update, the following diagnostic log appears in Console:

    oahd: [com.apple.oahd] Failed to translate binary chunk 0xad8b: Invalid Rosetta dyld shared cache

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

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

    Reinstalling Rosetta 2 runtime daemon and rebuilding LaunchServices database.

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

    1. Force reinstall Rosetta 2: 
      softwareupdate --install-rosetta --agree-to-license
    2. Reset LaunchServices database: 
      /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
    3. Kill daemon to rebuild fresh cache: 
      sudo killall -9 oahd

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