Hey all, not sure if this is a stupid question. Recently I went to change a file permission on my Mac, I clicked Get Info and I went down saw that it said my name and "everyone" under Sharing and Permissions. I clicked the + button to add a user and I saw my name there and Administrator and then _fpsd Who or what is _fpsd? Has someone hacked into my Mac? Is someone using my Mac? I can't see them under Users & Groups in System Preferences. How should I remove _fpsd if someone else is in my Mac? Any feedback would be great, thanks!
