# Install and updates

Thinair for macOS is free and needs no account. It installs like any app and keeps itself up to date from a signed feed.

## What you need

* **macOS 26 or later, on Apple silicon.** Thinair for Intel Macs is coming soon.
* **Windows** is coming.

No account is needed. On your computer everything works without signing in: every
app, Native VMs, Profiles, and any coding agent you start in a Terminal.

## Install

1. Download Thinair for macOS from [Get Thinair](/get-thinair).
2. Open the disk image and drag Thinair to Applications.
3. Open Thinair. It sets up its background service, which macOS shows as
   **Thinair OS**, and takes the rest of itself from Thinair's update feed.

Every piece of Thinair is checked against its signed record before it runs, the first
time and every time after.

## Updates

Thinair updates itself in place from a signed feed, with no account. Most updates
apply while you work. An update to the app itself waits for you: it shows at the top
of the Notifications panel and in **Thinair Settings ▸ Updates**, with **Restart to
update**.

A restart ends no login shell. Your Terminals keep running, and so do the apps in
your VMs: they reconnect as Thinair comes back. If a new version of the app fails to
start, Thinair puts the one before it back.

## Offline

Thinair starts without a network, from the version it applied last, and follows the
update feed again once it can reach it.

## Next

* [Where your work runs](/docs/concepts/places): places, apps, Profiles and agents in
  one page.
* [Get Started](/get-started): give an agent its first task.
