My Avast Mac Security, 13.11, “Cannot be opened because of a problem.” Apple’s report identifies the termination cause as “DYLD, [0x1] Library missing.” Apple support says this is the key information, but further detail is available:
Dyld Error Message:
Library not loaded: @rpath/libprotobuf-lite.8.dylib
Referenced from: /Applications/Avast/Avast.app/Contents/MacOS/Avast
Reason: image not found
Hello Mr. sbbrenner,
It is strange that you have Avast installed in /Applications/Avast/Avast.app. Our Installer does not allow that and we are installing to /Applications/Avast.app. Did you by any chance move Avast.app manually? Please move Avast.app back to /Applications folder and try again.
I suppose Avast UI will start after that, but you might experience some issues with our services not running. They should fix themselves in a few minutes. If they do not, please try to restart your Mac.
Best regards,
Jakub
