_fpsd user?
I have a maybe simple question regarding users and permissions. When I attempt to modify the permissions in the finder with the "Info" option, I am able to add permissions for an invisible user "_fpsd".
I've not seen this before, because I usually use CHMOD in the terminal to modify permissions, but I am curious as to where this user comes from. They are not in the user list, as this is a laptop with only one user, the admin.
Is anyone familiar with why I am seeing this user and group info with a user I am not familiar with? Likely a software agent of sorts, just wanting to know why. It is likely a common issue?
