Share files with others who use your Mac
People who use the same Mac with different user accounts can share files with one another using the computer’s Shared folder or using their individual Public and Drop Box folders.
The computer’s Shared folder is located in Macintosh HD/Users. Your Public folder is located inside your home folder, and your Drop Box folder is located inside your Public folder.
Make a file available to all users of your Mac
You can use either the computer’s Shared folder or your Public folder to make an item available to other users.
On your Mac, do any of the following:
Put a file in your Public folder: Click the desktop to make sure you’re in the Finder, choose Go > Home, then drag the file (or a copy of it) into your Public folder.
Put a file in the computer’s Shared folder: Click the desktop to make sure you’re in the Finder, choose Go > Go to Folder, type in /Users/Shared, click Go, then drag the file (or a copy of it) into the Shared folder.
Files in a user’s Public folder or in the Shared folder can be read by all users of the Mac, but edited or deleted by only the owner of the file. If you want to allow other users to edit those files, you need to change the file permissions. See Change permissions for files, folders, or disks on Mac.
Use a drop box to share a file with another user of your Mac
You can use drop boxes to share files with individual users.
In the Finder on your Mac, choose Go > Go to Folder.
Enter /Users/[username]/Public, then click Go.
Drag the item (or a copy of it) into the Drop Box folder.
Even though you can put items in another user’s Drop Box, you can’t open any Drop Box except your own.
