The “Disk Not Ejected Properly” notification is a macOS feature designed to alert users when an external storage device is disconnected without being properly ejected. This can lead to potential data corruption or loss if files are being written to the disk at the time of disconnection.
While the notification is important for data safety, it can clutter your notification center if ignored or dismissed repeatedly.
macOS stores these notifications in the Notification Center, and they remain visible until manually cleared. For users who frequently disconnect devices without ejecting them, this can result in a buildup of notifications. Automating the clearing process can save time and reduce clutter.
Using Terminal Commands to Clear Notifications
One effective way to clear notifications automatically is by using Terminal commands. macOS provides a command-line interface that allows you to interact with the system at a deeper level. By running specific commands, you can clear all notifications, including the “Disk Not Ejected Properly” alerts.
To clear notifications using Terminal:
- Open the Terminal application. You can find it in Applications > Utilities > Terminal.
- Enter the following command:
defaults write com.apple.notificationcenterui bannerTime 0. - Press Enter to execute the command.
- Restart your Mac for the changes to take effect.
This command disables banner notifications temporarily. To re-enable them, use the command defaults write com.apple.notificationcenterui bannerTime 10 and restart your Mac.
Automating Notification Clearing with Scripts
For a more permanent and automated solution, you can create a script that clears notifications at regular intervals. This method requires basic knowledge of scripting and the use of macOS’s Automator or a third-party automation tool like Keyboard Maestro.
To create an automation script:
- Open the Automator application from Applications > Utilities > Automator.
- Create a new document and select Quick Action as the type.
- Set the workflow to receive no input.
- Add a Run Shell Script action to the workflow.
- Enter the following script:
defaults write com.apple.notificationcenterui bannerTime 0. - Save the workflow and set it to run at specific intervals using macOS’s Calendar or a third-party automation tool.
This script will automatically clear notifications, including “Disk Not Ejected Properly” alerts, without requiring manual intervention.
Using Third-Party Tools for Notification Management
If you prefer a more user-friendly approach, third-party tools like MacPilot can help manage and clear notifications. These tools provide graphical interfaces and additional features for managing macOS notifications.
To use a third-party tool:
- Download and install the tool of your choice.
- Launch the application and navigate to the notification management section.
- Select the option to clear all notifications or set up automated clearing.
- Configure the tool to run at startup or at specific intervals.
These tools simplify the process and are ideal for users who are not comfortable with Terminal commands or scripting.
Preventing “Disk Not Ejected Properly” Notifications
While automating the clearing of notifications is helpful, preventing the notifications altogether is a more efficient solution. Always eject external drives properly before disconnecting them. macOS provides several ways to eject drives:
- Drag the drive icon to the Trash in the Dock.
- Right-click the drive icon on the desktop and select Eject.
- Use the eject button next to the drive name in Finder.
By following these steps, you can avoid the “Disk Not Ejected Properly” notification entirely.
