FAQPage Schema

How do I send notifications from tmux scripts on macOS?▼

Send notifications from tmux by using osascript with reattach-to-user-namespace to invoke macOS System Events display dialog. This method bypasses tmux's environment isolation, ensuring modal alerts appear reliably without requiring notification permissions.

Why don't my terminal notifications work in tmux?▼

Terminal notifications often fail in tmux because the session lacks access to the user's display server. Using reattach-to-user-namespace with osascript restores that access, delivering guaranteed modal dialogs that work consistently across all tmux environments.

Can I customize macOS alert dialogs for different notification types?▼

Yes, macOS System Events display dialog supports customizable titles, messages, and icons. You can configure auto-dismiss timers and visual styles for different alert types—task completion, errors, or event notifications—all triggered reliably from terminal scripts.

Do I need notification permissions to display macOS alerts from scripts?▼

No, System Events display dialog does not require notification permissions. It creates modal alerts that auto-dismiss after five seconds, making it ideal for long-running scripts and automated workflows that need guaranteed user attention without configuration overhead.

What's the best way to alert users when background tasks complete?▼

Use modal macOS alerts triggered by osascript through reattach-to-user-namespace for guaranteed visibility in any terminal environment. This method ensures task completion, error states, and important events display reliably without constant terminal monitoring.
