Though I had never used a Macbook before this week, I remembered that the Dock usually had some kind of animation when you move the mouse over it. That apparently isn’t the default setting and I was kind of disappointed that it didn’t change or move.
You can find the settings for the Dock by clicking on the Apple symbol in the top left side of the screen:
By switching the Turn Magnification On/Off you can switch the effect On of Off. Choose Dock Preferences to change the size of the magnification. If you want the dock to disappear when you’re not using it, you can change that there also.
