Here are quick ways to adjust the dock’s size and location.To adjust the size, look for the dotted line at the far right (or bottom). Click on the dotted line and drag up or down – the dock will automatically get larger and smaller. To quickly change the location of the dock, go to the Apple menu (at the far left of the menu bar). Click on the APPLE and then on DOCK – you’ll see options to move the dock to the left, bottom or right of your screen. Very handy!
