    I want to share everything on an iMac with other Macs using File Sharing, though I am concerned with the possibility of someone else getting into the iMac with the sharing turned on. I just checked the settings and it shows that only one user has access to read & write to the Mac and Everyone else has No Access. Well, I just got a new Mac and it is not on this list, though it lets me right into my Mac. Is this because it is logged into the same iCloud account? Is the user based on the iCloud account and not the Mac itself?

    1. What extra security, if any, can I take to protect the Mac from others?

    I believe you can require user names and passwords when you set up the file sharing.

    Check Accounts in Settings--perhaps you have allowed guest access to file sharing.

    What is the name of the allowed user? Is it the same as the account/user name on the second computer?

    Home environment, or business/enterprise environment?

    only enable AFP sharing and disable SMB sharing under File sharing options. Permissions are local.
