Re: MAC OS High Sierra update (10.13.3 version) won't allow Norton Suite to load and protect
I experienced the same/similar issue on March 2, 2018. Norton kept indicating my security was at risk and I needed to do a fix now. I tried the fix now several times, then did a clean uninstall and reinstalled it and experienced the same issues. After 2 hours I finally gave up when I could not find a solution to this Norton problem and did an alternate solution.
