In some cases, you may need to boot your Mac in Recovery mode and run the Disk Utility from there. You can use the Disk Utility to verify and repair your disk’s integrity. Large amounts of hidden disk space may also indicate errors in the file system. For example, here’s how you delete a snapshot created by CCC.

In order to reveal and delete such snapshots, please use the corresponding third-party apps. You can check for presence of any third-party snapshots using tmutil listlocalsnapshots / command in Terminal. Unlike the Time Machine snapshots, the third-party snapshots are not counted toward the purgeable space, but toward the still hidden space. If you are using third-party backup tools such as Carbon Copy Cloner (CCC), they can create their own file system snapshots. The purging may be additionally delayed if the Time Machine is in process of backing up. Please allow some time (from few seconds to few minutes) before the system completes reclaiming the purgeable space in the background. DaisyDisk will automatically refresh (without rescanning) the numbers or hidden and purgeable space after the system updates them globally.Īlso, just after you delete the purgeable space, you may temporarily see the hidden space being “borrowed” by the corresponding amount.

During this delay, you may temporarily see the hidden space being “borrowed” by the equal amount. However, the system often delays updating the size of the purgeable space by few minutes. When you delete a file or folder and Time Machine is turned on, the system may not delete the files entirely, but move them to the purgeable space, causing it to grow by the corresponding amount. Usually this space is used by the file system itself. Note that some small amount of hidden space (a few GB) may still remain even after scanning as administrator. And in reverse, some other folders will grow in size correspondingly, and restricted files and folders will become visible here and there on your disk. The hidden space should disappear, or become significantly smaller by size. MacOS Mojave or later: Make sure your grant DaisyDisk the full disk access, then relaunch DaisyDisk and rescan your disk.

other volumes (covered in a separate article) - sub-volumes within the same physical disk that share its pool of free space (a new feature of APFS).

purgeable space (covered in a separate article) - mostly local snapshots of Time Machine, and also swap files, sleep images and other temporary system files.

The following items typically contribute to the hidden space: When you click on it, you see a further breakdown of the hidden space: DaisyDisk detects the remainder of space and displays a special item hidden space of the corresponding size. This happens because there may be some restricted folders, which DaisyDisk couldn’t scan with default permissions, or which are even entirely unreachable. Sometimes the total size of all scanned files and folders on a disk still don’t make for the entire used space on that disk.
