Mac Internet Sharing

A Python CLI tool to manage internet sharing on macOS.

Installation

pipx install mac-internet-sharing

Usage

The tool provides several commands to manage internet sharing. Here are some common use cases:

Starting Internet Sharing

There are two methods to start internet sharing:

1. Manual Configuration (configure)

This method requires you to manually specify the primary network interface and one or more device UDIDs. It sets up internet sharing based on your initial configuration. Note that newly connected USB devices after the initial setup are not added automatically—you will need to re-run the command to update the configuration.

sudo misha configure -n <primary_interface> -u <udid> -u <udid> -s

• <primary_interface>: Replace with your network interface name (e.g., "Ethernet Adapter (en6)").
• -u <udid>: Optionally specify one or more device UDIDs.
• -s: Automatically start sharing after configuration.

2. Automatic USB Detection (plug-n-share)

This method continuously monitors for new USB devices and automatically updates the sharing configuration when a new device is detected. It is ideal if you frequently plug in different devices and want your sharing setup to update in real time. You can also run it as a daemon.

sudo misha plug-n-share -n <primary_interface> -t <timeout>

• <primary_interface> (optional): Specify the network service name. If not provided, the default network service is used.
• -t <timeout>: Set the polling interval in seconds (default is 5 seconds).

Note: The manual configuration (configure) does not automatically detect newly connected devices after the initial setup. Use plug-n-share if you require automatic updates.

Toggling Internet Sharing

Manage the sharing state with the following commands:

• Turn Sharing Off:

  sudo misha off

• Turn Sharing On:

  sudo misha on
