The MacBook Pro features a multi-touch trackpad used to interact and navigate the computer screen. You can swipe and zoom the pad with your fingers to zoom in and flip Web pages on the screen. Occasionally, the trackpad may freeze up when it can't process the finger movements quick enough. Reset the MacBook Pro to get the trackpad working again and unfreeze the screen.
