Macbook Air Won’t Shut Down
Look For Apps And Services That Require Your Attention:
Nothing turns the laptop off — it just sits there humming instead of shutting down. Wait for 5 to 10 minutes to make sure that it really has a problem, then take a cursory look around MacOS. Are there warning signs, alerts, or active apps that need your attention before shutting down? Look for subtle signs that show something is happening behind the scenes, like bouncing apps in the Dock.
Check For Frozen Apps:
Right-click on an app icon and choose Force Quit to end the app and see if this restores functionality. If you only see Quit, press and hold the Option key, and it should change to Force Quit.
Force A Total Shutdown:
Hold down the Power button for at least 10 seconds to make the Apple Mac turn off. However, this can be dangerous if it’s trying to update. Make absolutely sure that everything is stuck and your MacBook isn’t just taking some personal update time.
