# @file macOS WireGuard Profiles
# @brief Installs WireGuard VPN profiles on macOS devices
# @description
#     This script installs WireGuard VPN profiles on macOS. It scans `${XDG_CONFIG_HOME:-$HOME/.config}/vpn` for all the `*.conf` files
#     and then copies those profiles to `/etc/wireguard`. It also performs a couple preparation tasks like ensuring the target
#     WireGuard system configuration file directory exists and is assigned the proper permissions.
#
#     ## Creating VPN Profiles
#
#     More details on embedding your VPN profiles into your Install Doctor fork can be found by reading the [Secrets documentation](https://install.doctor/docs/customization/secrets#vpn-profiles).
#
#     ## TODO
#
#     * Populate Tunnelblick on macOS using the VPN profiles located in `${XDG_CONFIG_HOME:-$HOME/.config}/vpn`
#     * For the Tunnelblick integration, ensure the username / password is populated from the `OVPN_USERNAME` and `OVPN_PASSWORD` variables
