  4. Choose View > Show All Devices.

  5. In the sidebar, select the disk you want to repair.

  7. Click Run.

    If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. You can click Show Details to see more information about the repairs. Otherwise, you may need to do one of the following.

    • If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.

      • If you can replace a file or re-create it, delete it.

      • If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.

    • If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall macOS, then restore your backed-up data.

If your Mac has a Fusion Drive and you see a flashing question mark or alert, see the troubleshooting section of the Apple Support article About Fusion Drive, a storage option for some Mac computers.

For instance, the Windows SoftwareDistribution folder can take over 50GB of space and that folder is not somewhere you or a cleaning program would usually check. The standard thing to do would be to check the properties of each top level folder and navigate your way down until the culprit files and folders are found. Cache files are files that help your Mac run programs a bit more smoothly. Think of them like blueprints for a house: your Mac has the blueprints for how a program is supposed to load/run/look, so it loads it faster; without them, it’d be like building it from scratch.

Checking on MacOS is simple.

If you continue to have problems with your disk or it can’t be repaired, it may be physically damaged and need to be replaced. For information about servicing your Mac, see Find out how to service or repair your Mac.
