Question: SafariBookmarksSyncAgent is Using 80+GB of Memory

On My Late 2013 iMac SafariBookmarksSyncAgent is Using 80+GB of Memory and its slowing my computer down like crazy. Ever Since I Updated To High Sierra after using my computer for about 15 min the process starts to jump up to 80+ GB gradually. Is There Anyway To Fix This? Thanks- Carter

Your systems is quite a mess.

  • Reopen the EtreCheck report and click the link to remove the adware you have installed.
  • While in the report also click the link(s) to remove all the Orphan files on your system.
  • Next, you have a large amount of Internet Plugins installed, evaluate which you do and do not need and eliminate the "do not" need list.
  • Finally get another external HD and begin moving large libraries (music, movies, photos) to the new EHD.
