> Install Blame on macOS, Windows, or Linux, with a package manager or a direct download.

Blame is a desktop app for macOS, Windows, and Linux. Install it with your package manager, or download it from [blame.so/download](https://blame.so/download).

## macOS

```bash
brew install --cask rchrp/tap/blame
```

Or download the disk image for your Mac:

- Apple silicon: [`blame-mac-arm64.dmg`](https://download.blame.so/latest/blame-mac-arm64.dmg)
- Intel: [`blame-mac-x64.dmg`](https://download.blame.so/latest/blame-mac-x64.dmg)

Blame needs macOS 13 or later. The app is signed and notarized. On first launch, Blame sets up a small Linux VM (based on [Lima](https://lima-vm.io)) where agents, worktrees, and previews run.

## Windows

```powershell
winget install Blame.Blame
```

Or download the installer: [`blame-win-x64.exe`](https://download.blame.so/latest/blame-win-x64.exe).

Blame needs Windows 10 or 11 with WSL 2. It runs agents in its own WSL distribution. If WSL is not installed, run this in an administrator terminal, then restart:

```powershell
wsl --install
```

The installer is not code-signed yet (signing through SignPath Foundation is [pending](https://blame.so/code-signing-policy)), so SmartScreen may warn you: choose **More info → Run anyway**. The installer lets you turn off usage telemetry and the update check at launch.

## Linux

Download the package for your distribution (x86_64):

- [`AppImage`](https://download.blame.so/latest/blame-linux-x86_64.AppImage)
- [`.deb`](https://download.blame.so/latest/blame-linux-amd64.deb) for Debian and Ubuntu
- [`.rpm`](https://download.blame.so/latest/blame-linux-x86_64.rpm) for Fedora and RHEL

```bash
# AppImage
chmod +x blame-linux-x86_64.AppImage && ./blame-linux-x86_64.AppImage

# Debian, Ubuntu
sudo apt install ./blame-linux-amd64.deb

# Fedora, RHEL
sudo dnf install ./blame-linux-x86_64.rpm
```

Blame needs Docker Engine with the Compose plugin. Worktrees stay native, and previews and project services run in Docker on your machine.

<Callout title="Arch Linux">
  An AUR package (`blame-bin`) is coming soon: it is ready and waits for AUR account registration to reopen. Until then, use the AppImage.
</Callout>

## Verify a download

Each release ships a `SHA256SUMS` file. Download it next to the installer, then run:

```bash
shasum -a 256 -c SHA256SUMS --ignore-missing
```

The [code signing policy](https://blame.so/code-signing-policy) explains how releases are built and signed.

## Updates and betas

Blame keeps itself up to date from its [GitHub releases](https://github.com/rchrp/Blame/releases). You can also pick any version there, including betas.

To get prereleases as soon as they ship, turn on **Settings → Desktop → Beta channel**.

## Next

Open Blame and choose **Continue without an account**. The [quick start](https://blame.so/docs/quick-start) takes you from there to your first merge.
