Installing the new LanguageTool macOS app is easy. 

If you also want to use LanguageTool additionally as an editor, download the LanguageTool Editor from the Mac App Store. Follow these steps for a successful installation:

  1. Download the Mac App. Unzip the app and drag it from your downloads folder into your applications folder. Open the app from there. You are greeted by a window that prompts you to accept our privacy policy.
  2. Click on “Grant Permission” and then on “Open System Preferences.”
  3. Grant accessibility rights to the app. LanguageTool requires permissions to access your written text in third-party applications such as Apple Mail. We won’t check texts, if you haven’t whitelisted an application. Unlock your settings and allow accessibility for each app individually by using checkmarks.
  4. Open any of the supported apps (see list below). As a shortcut, you can use the button in the step-by-step guide to open Notes. Alternatively, you can just open any of the supported apps.
  5. Enable checking for the app currently open. Once a supported app is open, you can click on the LanguageTool icon in the top right of your Mac’s menu bar to open the toolbar menu. Here, you can enable checking for the specific app (if supported). In addition, you can choose to enable picky mode either globally or per application. Any application has to be enabled that way. If you want to disable an application for checking, open the toolbar menu while the application is open and turn off the checking toggle.
  6. Once you enabled one application, there’s the option to enable more of the supported apps. You can either decide to enable more or skip this step for now. More applications can always be enabled using the toolbar menu or the apps settings.
  7. Click on “Finish Setup” and start using the Mac App.
