Installation

Detailed installation and troubleshooting guide.

System Requirements

  • macOS 10.15 (Catalina) or later
  • Internet connection for AI API calls
  • API key from OpenAI or Google Gemini

Installation Steps

1. Download

2. Install

  • Open the .dmg file
  • Drag Grammar Assistant to Applications folder
  • Launch from Applications

3. Security Prompt (First Launch)

If you see: "Grammar Assistant is damaged and can't be opened"

This happens because the app is not code-signed. Fix it:

bash
sudo xattr -rd com.apple.quarantine "/Applications/Grammar Assistant.app"

Alternative method:

  1. Right-click (or Control-click) the app → Open
  2. If still blocked, open Terminal and run the command above

If you see: "Grammar Assistant cannot be opened because the developer cannot be verified"

  1. Right-click the app → Open
  2. Click Open in the confirmation dialog

TIP

These are one-time steps. macOS will remember your choice.

4. Grant Accessibility Permission

Required for Cmd+Shift+G to work:

  1. System SettingsPrivacy & SecurityAccessibility
  2. Click 🔒 to unlock (enter password)
  3. Click + button
  4. Find and add Grammar Assistant
  5. Restart the app
Why is this needed?

Accessibility permission allows:

  • Monitoring Cmd+Shift+G shortcut globally
  • Auto-copying selected text
  • Working across all apps

The app only activates when YOU press the shortcut.

Troubleshooting

"App is damaged" Error

If you see "Grammar Assistant is damaged and can't be opened":

bash
sudo xattr -rd com.apple.quarantine "/Applications/Grammar Assistant.app"

This removes the quarantine flag that macOS adds to downloaded apps.

Shortcut Not Working

Check:

  1. ✅ Accessibility permission granted?
  2. ✅ App is running?
  3. ✅ Tried restarting the app?

Still not working?

  • Some apps may block shortcuts (rare)
  • Check macOS keyboard shortcuts for conflicts
  • Try in a different app (e.g., TextEdit)

App Crashes or Won't Start

  1. Check macOS version (10.15+)
  2. Try deleting app and reinstalling
  3. Check Console.app for error logs

API Key Issues

  • Make sure you copied the full key (no spaces)
  • Verify key is active on provider's dashboard
  • Check internet connection

Uninstalling

  1. Quit Grammar Assistant
  2. Move app to Trash from Applications
  3. (Optional) Remove settings:
