One of the macbooks biggest issues is the Dashboard feature. Its safe to say no one really uses this feature. I am not sure why Apple has left it on but none the less. I am going to show you well...tell you how to remove it. Its quite simple hence why I didn't make a video about it.
1. Open up terminal (if you don't use this just go to the spotlight and type terminal and open it from there)
2. Type in as followed. "defaults write com.apple.dashboard mcx-disabled -boolean true" (probably easier to copy and paste
3. After that relaunch your dock by typing in killall Dock
4. Thats it. Dashboard should be removed. Comment if you need help.
