Speed up MacOS boot up

To speed up the MacOS boot up time, we disable some unused features by using running following command on Terminal.

To Disable Dashboard
Dashboard is that desktop space that lets you add widgets like Weather and Calculator. But if you never use these widgets you remove dashboard from your computer.

  1. Open Terminal by searching for it in Spotlight or opening it from the Applications > Utilities folder.
  2. Enter the following command:
    defaults write com.apple.dashboard mcx-disabled -boolean YES
  3. Next you have to restart Finder. Enter the following command:
    killall Dock

    It will automatically restart.

Dashboard is now gone from your computer! To get it back: Follow the same steps but change -boolean YES to -boolean NO.

To disable Notification Center
If you don’t need the Notification Center feature introduced in OS X Mountain Lion, you can easily disable it with a Terminal command.

  1. Open Terminal by searching for it in Spotlight or opening it from the Applications > Utilities folder.
  2. Enter the following command
    launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
  3. Next you have to close Notification Center. Enter the following command:
    killall NotificationCenter

    If you see an error reading that there was no process, don’t worry.

And right away, you will see that the Notification Center icon is gone from the menu bar! If you need to get it back:

  1. Enter the following command in Terminal
    launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
  2. Hit Command+Shift+G in Finder and go to /System/Library/CoreServices/ then find “Notification Center” and double-click it to launch it.
