How to Enable or Prevent Reopen Windows when logging back in after Restart or Shutdown on Mac

When your apps windows reopens during restart or shutdown, this behaviour can help save some quality time. Especially because you can quickly jump in and continue what you were doing. But if you prefer to disable or enable this feature (like wanting to pick off where you left on your Mac device after restart or shutdown), then you are at the right place. In this guide, I will be showing you how to enable or prevent apps from automatically reopening when you log in to your Mac. Kindly refer to the following related guides: How to prevent a remote shutdown and restart in Windows, and Cannot uninstall the OneDrive App: The item “OneDrive” can’t be moved to the Bin because it’s open on Mac, how to logoff, restart, or shutdown Windows PC or Server remotely via Command Prompt and PowerShell,

There is a difference between Restart and Shutdown operation and this is quite self-explanatory. As for shut down, your Mac won’t start until you press the Power button again. It will interest you to know that newer macOS have an automatic reboot feature built-into them. As a result, the ‘shut down’ or ‘restart’ process clears everything, including processes, cache, and memory. This provides the device with a fresh start by completely clearing all previous data.

In contrast to before, when you restart your Mac, it reloads previously active apps. The device brings back apps that were open before the restart, operating differently from earlier. This action involves reopening all windows that were active at the time of the restart. Specifically, I’ll walk you through the steps required to either Enable or Prevent Reopen Windows after a shutdown or restart on Mac.

Use the setting in the logout or restart dialog to Enable or Disable reopen windows at login time

If you disable a login item from the Mac Dock, but it still appears again after you reboot your Mac, then, you may have your MacBook set up to restore all open apps when booting up or restarting. To clear the reopen windows functionality, please follow the following steps:

Click on the Apple menu, then select Restart or Shut Down from the drop-down list.

Disable Reopen Windows at login: Uncheck the Reopen windows when logging back in option. Then click on the Restart or Shut Down button to activate the process.

Enable Windows Reopen at Login: check the Reopen windows when logging back in option. Then click on the Restart or Shut Down button to activate the process.

Use the setting in General preferences

The same behavior can be achieved by using the General settings as shown below. To enable or prevent apps from remembering the windows they had open, choose Apple menu  > System Preferences.

In the System Preferences window, click on General as shown below.

In this panel, please check the box ”Close windows when quitting an app” to disable it or uncheck the box to enable it.

Alternatively, press and hold the Shift key while opening an app. This doesn’t change the setting, but the app forgets any windows that were open the last time you quit the app. If these steps don’t work for an app, the app might have its own setting for reopening windows.
