# Install Ouros X on Mac

## Choose the right download

Open [Download Ouros](https://ouros.md/download). The stable **2.1.16** download is for **Apple Silicon** and requires **macOS 26.0 or later**.

- **Apple Silicon** means a Mac with an Apple M-series chip.
- **Intel** means an Intel Mac. Use a download only if Intel is explicitly listed. No public Intel Mac download is available.

You can find your chip and macOS version in **Apple menu → About This Mac**. The Linux preview is a different app, not an installer for your Mac.

The 2.1.23 Mac preview has been withdrawn and is no longer available for download. Its [release notes](/docs/ouros-x/releases/2.1.23) remain available as a record of that build.

## Install the stable download

1. Save your work and quit your existing Ouros X normally. Keep your notes, settings and application data. Finish or save active terminal work before quitting.
2. Download the Apple Silicon Mac disk image from the stable download action.
3. Open the downloaded `.dmg` file.
4. Drag **Ouros X** to **Applications**. Replace the existing app only after it has quit; keep an existing copy if you need to retain it.
5. Eject the disk image, then open **Ouros X** from Applications.
6. Follow normal macOS verification and grant only the permissions you want to use.
7. Open **About Ouros X** and confirm **2.1.16**.

If macOS reports a damaged app or cannot verify it, stop and download it again from the official page. Do not remove quarantine attributes, disable Gatekeeper or use a Terminal command to bypass a warning.

## Updates and existing work

**Check for Updates** uses the stable channel. It does not fetch local preview builds. If you already use a newer local build, do not assume an older stable version is a safe downgrade for its data. Keep your work and check the release notes before changing versions.

Do not delete your notes or application data to update. See [compatibility](/docs/ouros-x/compatibility) and [shortcut troubleshooting](/docs/ouros-x/troubleshooting) if the controls differ from a guide.
