I was under the impression that the recent security update for El Capitan 10.11.6 contains required fixes. I am doing a clean install and upgrading all the way and check the PoC for any red flags. I will update here my findings. +1 for not upgrading to High/Sierra. Update: According to https://support.apple.com/en-us/HT208331 https://support.apple.com/en-us/HT208331 the Security Update 2017-005 contains fixes for Meltdown. Update 2: According to https://support.apple.com/en-us/HT208403 https://support.apple.com/en-us/HT208403 the Safari Update 11.0.2 contains fixes for Spectre. So folks on 10.11.6 El Capitan should be good.
