Won't shut downMediumMac won't shut down
What this error means
This means your Mac is not completing the normal shut down process. You may see the screen stay on, apps that keep spinning, or the Mac return to the desktop instead of turning off. It often happens when one app is still busy, a background process is stuck, or macOS is waiting for a window or update to finish closing.
Common causes
- 1An app is frozen and not responding to the shut down request
- 2A background process is using system resources or waiting to finish an action
- 3macOS has a pending update, save prompt, or disk issue that is slowing shutdown
How to fix it
- Save any open work if you can, then try shutting down again from the Apple menu. If a window asks you to save changes, respond to it first.
- If the Mac still will not shut down, force-quit any app that looks frozen. Press Option + Command + Esc, select the unresponsive app, then choose Force Quit.
- Close any apps that use a lot of memory or CPU, such as video editors, browsers with many tabs, or cloud sync tools. Then try shutting down again.
- Disconnect accessories that may be keeping the Mac busy, such as external drives, printers, hubs, or audio devices. Try the shut down process again after a few seconds.
- If the problem keeps happening, restart the Mac instead of shutting it down. After it starts again, install any available macOS updates and then try a normal shut down once more.
- If the Mac still hangs, boot in Safe Mode, then try shutting down from there. Safe Mode can help rule out third-party software or login items that are interfering with shutdown.
- As a last step, open Disk Utility and run First Aid on your startup disk. If First Aid reports a problem it cannot fix, back up your data and get help before making further changes.
Recommended fixes
Restart your device
A restart clears temporary state that often causes transient errors.

- Restart the device from the power menu.
- Reproduce the issue to check whether it persists.
Install macOS updates

- Install any available updates.
- Restart if prompted.
Close resource-heavy apps
- On Windows open Task Manager (Ctrl+Shift+Esc); on macOS open Activity Monitor.
- Sort by CPU or memory usage.
- Quit apps you don't need that are using excessive resources.
Boot into Safe Mode (Mac)
Apple silicon: shut down, hold the power button until startup options appear, select your startup disk, then hold Shift and choose Continue in Safe Mode.

Run First Aid in Disk Utility (Mac)
- Open Disk Utility.
- Select your startup disk and click First Aid.
- Let it verify and repair the disk.
When to seek help
Seek professional help if your Mac will not shut down after repeated tries, if it happens every time you use the computer, or if you also notice freezes, unusual noise, overheating, or messages about disk problems. Get help right away if the Mac is stuck on a dark screen for a long time, you suspect hardware damage, or you are unable to save important files.
