Access a Mac user’s Public folder and DropBox
Another Mac user on your local network can share files with you by putting them in their Public folder. You can also share your files with another local Mac user by putting them in their Drop Box (a folder inside the Public folder).
On your Mac, click the Finder icon in the Dock to open a Finder window, then select Network in the Locations section of the sidebar.
If no items appear in the Locations section of the sidebar, hold the pointer over the word Locations, then click the arrow .
Double-click the computer you want to share files with, click Connect As, then click Connect.
Select how you want to connect to the Mac:
Guest: You can connect as a Guest user if the shared computer permits guest access.
Registered User: Connect to the other Mac using a valid login name and password. If “Only these users” is selected on the other Mac, make sure the login name you’re using is on the list of allowed users.
Using an Apple ID: Connect to the other Mac using an Apple ID. You must be set up in Users & Groups settings with this Apple ID, on both this Mac and the other Mac.
If necessary, enter your username and password, then click Connect.
Tip: To make it easier to connect to the computer in the future, select "Remember this password in my keychain" to add your username and password for the computer to your Keychain.
Double-click the user’s Public folder.
If you don’t see a Public folder on the other Mac, make sure it has file sharing turned on. See Set up file sharing.
Do any of the following:
Drag files from the user’s Public folder to your computer.
Drag files from your computer to the Drop Box in the user’s Public folder.
When you’re done, click the Eject button next to the computer in the Locations section of the sidebar to disconnect from it.
If you know the computer name specified in the other user’s Sharing settings, you can connect to the other Mac by choosing Go > Connect to Server and entering the name.
