I have a Mac Pro, running OS X Yosemite, as a "server" for hosting my backups and file sharing within a personal network. What I would like to do is have a way for users to access this computer without needing to put in a username/password. I understand the security risks and I also understand I could do this with an airdrop or public folder, but it maintains multiple HDDs and a complex directory structure I am hoping to keep intact.

Currently there are two way users log onto this computer:

  • Via finder - the computer has file sharing on, and it appears to users in their shared or networked computers

With this method, users are asked to sign in as a registered user, guest or using an Apple ID - I would like them to be able to log in as a guest and have full rights to all volumes and subsequent folders

  • with a VNC client - using something like chicken, users are able to remotely login to the "server" and do various needed tasks

When logging in with the VNC client users are presented with the mac login screen (see screenshot below) - if possible, I would like users to bypass this login screen.

Any help would be appreciated, I am not sure if it is even possible, but after exhausting all attempts of changing settings I figure this would deb my best bet for find help.

mac pro - vnc login


I don't think using a VNC client is the best or easiest option for file-sharing, since that's mainly for screens-sharing & remote control.

Anyway, based on the info I read from this site (I don't use a Mac), you could go to System Preferences > Sharing then click on Options and enable the checkbox "Anyone may request permission to control screen" instead of the last checkbox that requires a password. enter image description here

    Thank you for the reply, unfortunately that setting then disallows the use of a VNC client. – justinw Mar 24 '16 at 3:30
  • I have EXACTLY the same problem and question, would be great if someone could give an valid answer. I have even tried to disable the system login (enable automatic login) but this action doesnt disable the login for the vnc. – Rudolf Schmidt Jul 11 '18 at 19:34

this is the command to write in a terminal window:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement VNCAlwaysStartOnConsole -bool true
