I am running MacOS10.13.2 and McAfee 22.214.171.124(3859). The instructions you provide do not match the choices available in Sfari or McAfee. Bottom line, your help is not any help for me.
Using 10.13.6 on a Macbook Pro and Mcaffe update does not work (Error during update). Followed instructions on removing web data, public firewall, ... restart, reinstall, still will not update? Is there an update on how to fix this?
