Get to know one of the most powerful tools on your Mac.
Whether you need to better organize your hard drive or resolve disk errors, Disk Utility is the tool for the job. Built into macOS, Disk Utility allows you to view details on your hard drive, add or remove partitions and volumes, and check the disk for glitches. Here’s how it works.
To access Disk Utility while logged in, go to the Finder and click the Go menu, select Utilities, and then in the window that appears, double-click the Disk Utility icon. The tool displays details and a graph of your hard drive configuration, showing the overall capacity as well as the used and free space and the various volumes.
