macOS Slow Shutdown? Here’s Why It Happens and How to Fix It

By /

1. Your Mac Takes Forever to Shut Down? You’re Not Alone 🕰️

You click  → Shut Down, expecting a quick goodbye — but instead, the screen goes black, the spinner starts… and stays there. One minute. Two. Sometimes more. If macOS has a slow shutdown, it’s not just annoying — it can signal deeper issues.

In this article, we’ll break down why shutdowns take longer than they should, what’s actually happening in the background, and — most importantly — how to make your Mac shut down faster and more reliably.

2. What Happens During Shutdown? 🧠

When you shut down your Mac, it goes through a few critical steps:

  • Quitting all open applications
  • Closing background services and processes
  • Unmounting disks and volumes
  • Saving system logs and user preferences

If any of those steps fail or take too long, macOS will delay shutdown — sometimes for minutes. Let’s explore how to stop that from happening.

3. Force Quit Frozen Apps Before Shutting Down 🚫

Apps that don’t respond can delay or block shutdown. To avoid this:

  • Use Cmd + Option + Esc to open the Force Quit window
  • Close any apps marked as “Not Responding”
  • Check menu bar utilities that might be hanging (Dropbox, Zoom, Adobe)

💡 Tip: You can also try Command + Q on each app manually before shutting down.

4. Check Login Items That Linger in the Background

Some login items or background agents resist closing — even at shutdown. To clean them up:

  • System Settings → General → Login Items
  • Disable non-essential entries
  • Then scroll to “Allow in Background” and remove apps that don’t need to stay active

5. macOS slow shutdown? Unmount External Drives Before Shutdown 🪛

macOS delays shutdown if external disks (especially USB drives or network volumes) don’t unmount properly.

Before shutting down:

  • Eject external drives manually
  • Quit any apps using those drives (Final Cut, Photos, etc.)

This helps avoid long shutdown hangs caused by disk timeout issues.

6. Reset SMC and NVRAM to Fix Persistent Delays 🛠️

Corrupted power management data can cause repeated shutdown lags. Here’s how to reset:

  • Intel Mac – NVRAM: Reboot and hold Option + Command + P + R for 20 seconds
  • Intel Mac – SMC: Hold Shift + Control + Option + Power for 10 seconds, then power back on
  • Apple Silicon: Shut down completely, wait 10 seconds, then restart

7. Use Terminal to Diagnose Long Shutdowns

After a slow shutdown, open the Terminal app and type:

log show --predicate 'eventMessage contains "Previous shutdown cause"' --info

This shows why your Mac shut down last time — including any errors or hangups.

You can also search for phrases like shutdownstall or shutdown delay in the Console app to dig deeper.

8. Try Safe Mode to Isolate Third-Party Interference

Safe Mode disables login items and extensions that might slow shutdowns:

  • Intel Macs: Restart and hold Shift until the Apple logo appears
  • Apple Silicon: Hold Power → Options → press Shift → Continue in Safe Mode

Test shutdown time in Safe Mode. If it’s fast, you know something in your usual environment is causing the delay.

Extra Tip 💡

If your Mac hangs specifically during shutdown after system updates, this might be caused by launch agents left over from previous macOS versions. You can manually check:

/Library/LaunchAgents  
/Library/LaunchDaemons  
~/Library/LaunchAgents

Move unknown or unnecessary files to a backup folder and test again.
