# Install the app

> Install Umbreta with one command on macOS with Apple Silicon and on Windows x64; updates and uninstalling.

After this page the Umbreta app is installed and keeps itself up to date.

## You need

- macOS 12 or later on Apple Silicon, or Windows x64. Intel Macs are not supported.
- No administrator rights.

## Steps: macOS

1. Open **Terminal**.
2. Paste the command and press Return:

   ```sh
   curl -fsSL https://anty.igrudsky.dev//api/v1/desktop-app/install.sh | bash
   ```

3. Wait for the app to open by itself.

The script checks the archive's checksum against the published one and puts the app into Applications (or into the Applications folder in your home folder when the shared one is not writable). Running the command again reinstalls the app.

## Steps: Windows

1. Open **PowerShell**.
2. Paste the command and press Enter:

   ```powershell
   irm https://anty.igrudsky.dev//api/v1/desktop-app/install.ps1 | iex
   ```

3. Wait for the app to start by itself.

It installs for your user, with no administrator rights, and adds shortcuts to the Start menu and the desktop.

## Result

The app is open and shows sign-in. From now on it checks for updates half a minute after it starts and every four hours. A downloaded version installs when you quit the app; **Now** in the update-ready notice restarts the app at once. To check by hand: **Settings** → **Updates** → **Check now**.

## If it didn't work

- macOS says it can't verify the developer, or that the app is damaged: the app was downloaded with a browser. Delete it and install it with the command in Terminal. A file downloaded by the command doesn't get that mark.
- Windows shows SmartScreen: the installer was downloaded with a browser. Install it with the command in PowerShell, or in the SmartScreen window press **More info** → **Run anyway**.
- To uninstall on Windows: **Settings** → **Apps** → Umbreta → **Uninstall**.
