# Connecting an Apple client

## Goal

This documentation has the goal of showing how a user can use the official iOS and macOS [Tailscale](https://tailscale.com) clients with `headscale`.

!!! info "Instructions on your headscale instance"

    An endpoint with information on how to connect your Apple device
    is also available at `/apple` on your running instance.

## iOS

### Installation

Install the official Tailscale iOS client from the [App Store](https://apps.apple.com/app/tailscale/id1470499037).

### Configuring the headscale URL

- Open Tailscale and make sure you are _not_ logged in to any account
- Open Settings on the iOS device
- Scroll down to the `third party apps` section, under `Game Center` or `TV Provider`
- Find Tailscale and select it
  - If the iOS device was previously logged into Tailscale, switch the `Reset Keychain` toggle to `on`
- Enter the URL of your headscale instance (e.g `https://headscale.example.com`) under `Alternate Coordination Server URL`
- Restart the app by closing it from the iOS app switcher, open the app and select the regular sign in option
  _(non-SSO)_. It should open up to the headscale authentication page.
- Enter your credentials and log in. Headscale should now be working on your iOS device.
