Share Mac files with Windows users
To let users connect to your Mac from a Windows computer, turn on file sharing and enable SMB sharing.
Set up file sharing on the Mac
On your Mac, choose Apple menu > System Settings, click General in the sidebar, then click Sharing on the right. (You may need to scroll down.)
Turn on File Sharing, then click the Info button on the right.
Click Options, then turn on “Share files and folders using SMB.”
In the Windows File Sharing list, select the checkbox next to each user account that needs to share files with Windows users and enter the passwords for those users, then click OK.
Click Done, then click Done.
Choose View > Network, click your active connection, then click Details.
Click WINS in the sidebar, then enter the workgroup name used by the Windows computer.
Provide the information Windows users need
To connect to your Mac, Windows users need the network address for your Mac, and a user name and password to use to log in to your Mac.
To find your Mac computer’s network address, choose Apple menu > System Settings, click General in the sidebar, click Sharing on the right, then click the Info button next to File Sharing. (You may need to scroll down.) The address appears below the “File Sharing: On” indicator, and looks similar to smb://188.8.131.52/ or smb://computername.example.com.
Create an account on your Mac for each Windows user. To create accounts, choose Apple menu > System Settings, then click Users & Groups in the sidebar. (You may need to scroll down.) See Add a user or group.
If you want to use an account that existed before you installed the latest version of macOS, you may need to reset the password for the account in Users & Groups settings.
Because the passwords of user accounts used for Windows sharing may be stored in a less secure manner, turn off the account when it’s not being used. Before you turn off Windows sharing, turn off all the accounts you enabled. Otherwise, the passwords are still stored less securely.
