How to choose the right tool
- If you prefer no downloads and full control on Windows, use Windows Task Scheduler.
- For macOS native scheduling, use System Settings → Battery → Schedule or an AppleScript triggered by Calendar.
- If you need many trigger types on Windows, pick Shutter.
- For the simplest interface on Windows, use Wise Auto Shutdown.
- For media-related or timer-only shutdowns on Mac, use a Sleep Timer app.
Safety tips and troubleshooting
- Always save work before a scheduled shutdown; consider adding a pre-shutdown warning.
- Test schedules with a short delay (e.g., /t 60) so you can cancel if needed.
- If a scheduled shutdown doesn’t run, check permissions (task set to run whether user is logged on), and verify any third-party app isn’t blocked by antivirus.
- For scripts, run them manually first to confirm behavior.
