Create a File Sharing Account on Your MacBook
Sharing files on your MacBook with other Mac users is a piece of cake. Remember, however, that you need to create an account for anyone whom you want to have access to your files. The accounts that you create can access a maximum of three folders:
The account’s Home folder: That specific account’s Home folder carries a short version of the username that’s in the Users folder on your hard drive. The Home folder is noted with an icon that looks like a house, for the mark account.
The Home folder icon always bears the short account name for the user who’s currently logged in. (If you create a Sharing Only account, Lion doesn’t create a Home folder for that account.)
The account’s Public folder: Each Admin, Standard or Managed user account you create also has a Public folder located within its Home folder. Any files you place in the Public folder can be accessed by any user on your Mac. (Once again, Sharing Only accounts don’t have a Public folder.)
The Shared folder: This folder is also in the Users folder on your hard drive. Anyone with an admin-level account on your Mac can access the Shared folder across the network, and any user account on your Mac can access the Shared folder locally, so it’s a great place to keep common files that everyone wants to copy or use.
If you create a Sharing Only account, that user can only access the contents of the Shared folder. (Go figure.)
To create an account, you need to be logged in as an Admin user. Follow these steps:
Open System Preferences from the Apple menu (Command) or the Dock.
Click the Users & Groups icon.
Click the New User button, which carries a plus sign.
If the New User button is grayed out, you need to unlock the Users & Groups pane first. Click the padlock icon in the lower-left corner. If necessary, enter your admin-level user account password and click Unlock.
Click the New Account pop-up menu and choose the account type.
Fill in the appropriate information, including the name for the account and a password.
Note that the name that appears as the short name determines the name of that user’s Home folder.
Click Create Account.
Press Command+Q to exit System Preferences.
