Disk Utility is one of those apps that's been sitting in your Utilities folder for years, quietly minding its own business, and most people only open it on the worst possible day, when a drive stops behaving. In this Tuesday Tip, Lee takes the mystery out of Disk Utility. You learn how to make sense of that confusing sidebar, why your Mac shows several things all called Macintosh HD, and what containers, volumes, and snapshots are. Lee also shows you how to read what your Mac is telling you about your storage, including the oft-misunderstood question: how much free space do I have?

As you discover other actions like First Aid, Erase, Restore and even adding partitions to drives, you will soon realise that Disk Utility isn't quite as confusing as you may have thought it was.
