# Versions and keyboard compatibility

These walkthroughs use the native Mac app and named right-side modifier keys. A keyboard without Right Control can use Escape in the focused compact bar. A custom assignment or expanded view can change which action receives a key.

Check the app's **About Ouros X** entry for its installed version when comparing instructions or reporting a problem. Do not infer the installed version from a website or a download filename.

## When instructions and controls differ

- Check the action's actual label and current shortcut assignments.
- Distinguish a solo modifier tap from a chord containing that modifier.
- Preserve unsaved work before updating or restarting.
- Use **Open Ouros** from the app menu when diagnosing the opening shortcut.

This page is compatibility guidance, not a release history. It does not claim that an update is installed or that every source change is present on your Mac. See [shortcut troubleshooting](/docs/ouros-x/troubleshooting) for a focused recovery procedure.

## Settings and chat in the local update

[Ouros X 2.0.57](/docs/ouros-x/releases/2.0.57) is a local update under review, not a public stable download. Its [Settings](/docs/ouros-x/settings) layout keeps tabs fixed above the controls, and its [chat control](/docs/ouros-x/messages) is easier to click. Check your installed version before comparing these controls.

## Mac and Linux installation

The current public Mac download requires **macOS 26.0 or later** and is for **Apple Silicon**. The [2.1.23 Mac preview](/docs/ouros-x/releases/2.1.23) has been withdrawn. No public Intel Mac download is available.

Follow [Mac installation](/docs/ouros-x/mac-installation) for the architectures listed on the download page. The separate [Linux preview](/docs/ouros-x/linux-installation) has its own requirements and does not include every Mac feature.
