<h1>Apple configuration profiles</h1>
<p>
This page provides <a href="https://support.apple.com/guide/mdm/mdm-overview-mdmbf9e668/web">configuration profiles</a> for the official Tailscale clients for <a href="https://apps.apple.com/us/app/tailscale/id1470499037?ls=1">iOS</a> and <a href="https://apps.apple.com/ca/app/tailscale/id1475387142?mt=12">macOS</a>.
</p>
<p>
The profiles will configure Tailscale.app to use {{.Url}} as its control server.
</p>
<h3>Caution</h3>
<p>You should always inspect the profile before installing it:</p>
<p><code>curl {{.Url}}/apple/ios</code></p>
<p><code>curl {{.Url}}/apple/macos</code></p>
