 ## Prerequisites
 
-To use the SMB synced folder type, the machine running Vagrant must be
-a Windows machine with PowerShell version 3 or later installed. In addition to this, the command prompt executing Vagrant
-must have administrative privileges. Vagrant requires these privileges in
-order to create new network folder shares.
+### Windows Host
+
+To use the SMB synced folder type on a Windows host, the machine must have
+PowerShell version 3 or later installed. In addition, when Vagrant attempts
+to create new SMB shares, or remove existing SMB shares, Administrator
+privileges will be required. Vagrant will request these privileges using UAC.
+
+### macOS Host
+
+To use the SMB synced folder type on a macOS host, file sharing must be enabled
+for the local account. Enable SMB file sharing by following the instructions
+below:
+
+* Open "System Preferences"
+* Click "Sharing"
+* Check the "On" checkbox next to "File Sharing"
+* Click "Options"
+* Check "Share files and folders using SMB"
+* Check the "On" checkbox next to your username within "Windows File Sharing"
+* Click "Done"
+
+When Vagrant attempts to create new SMB shares, or remove existing SMB shares,
+root access will be required. Vagrant will request these privileges using
+`sudo` to run the `/usr/sbin/sharing` command. Adding the following to
+the system's `sudoers` configuration will allow Vagrant to manage SMB shares
+without requiring a password each time:
+
+```
+Cmnd_Alias VAGRANT_SMB_ADD = /usr/sbin/sharing -a * -S * -s * -g * -n *
+Cmnd_Alias VAGRANT_SMB_REMOVE = /usr/sbin/sharing -r *
+%admin ALL=(root) NOPASSWD: VAGRANT_SMB_ADD, VAGRANT_SMB_REMOVE

-## Limitations
-
-Because SMB is a relatively new synced folder type in Vagrant, it still
-has some rough edges. Hopefully, future versions of Vagrant will address
-these.
-
-The primary limitation of SMB synced folders at the moment is that they are
-never pruned or cleaned up. Once the folder share is defined, Vagrant never
-removes it. To clean up SMB synced folder shares, periodically run
-`net share` in a command prompt, find the shares you do not want, then
-run `net share NAME /delete` for each, where NAME is the name of the share.
