Last Dance

Toggle Samba file sharing automatically

Requires macOS Big Sur 11.0 or later

Last Dance solves a persistent macOS bug where SMB file sharing becomes unresponsive after restart. Install and run this app, and never worry about the state of file sharing ever again.

The app works by automatically disabling file sharing before your Mac shuts down or restarts, then re-enabling it when you log back in.

Automatic Fix

Toggles file sharing before shutdown and at login
Menu Bar

Runs quietly with status icon showing current state
One-Time Setup

Authorise once and forget about it forever

The Problem

macOS has a known bug where SMB file sharing can stop working properly after a restart. Other devices on your network lose the ability to connect to your Mac’s shared folders, requiring manual intervention to fix.

The Solution

Last Dance automates the fix: it watches for system shutdown and restart events, disables file sharing before the system goes down, and re-enables it at login. The workaround happens automatically in the background.

Menu Bar Status

Folder icon shows current file sharing state:
Person badge when sharing is enabled
Minus badge when sharing is disabled
Question mark badge when busy

Secure Implementation

Uses Apple’s SMJobBless for privileged helper installation
XPC communication for secure privilege escalation
Hardened runtime enabled
One-time administrator authorisation required

Simple Setup

Launch Last Dance
Authorise the privileged helper when prompted
The app starts automatically at login
That’s it—SMB issues are fixed forever
