Note that it may not delete everything because macOS may not be able to release all of it and it will also immediately start rebuilding temporary files as soon as it’s deleted. When finished, DaisyDisk will recalculate the new amount of purgeable space.Note that this may take a few minutes to complete depending on the size of the file. Daisy Disk however allows you to force a purge of the files so that you can reclaim this space immediately.ĭrag the purgeable space item into the DaisyDisk Collector and it will forceably delete it. If you expand that, you will see “Purgeable Space”.Īlthough macOS will eventually delete these purgeable items on its own, it may take some time. When you complete a scan of your hard drive with DaisyDisk, you’ll see a sector called “Hidden space”.DaisyDisk can locate and delete these files instantly. It also contains sleep images, caches and temporary system files.

Purgeable space mainly consists of local snapshots which your Mac makes periodically. It is simply factored into System files which isn’t very helpful and makes it appear that macOS system files are taking-up a huge chunk of hard drive space as you can see below. In previous versions of macOS, going to About This Mac > Storage clearly showed the amount of purgeable space on your Mac: Since High Sierra however, Purgeable space is no longer displayed in macOS. DaisyDisk has long been the best utility to find large files or recover disk space on Mac but has now been updated to find and delete snapshots and “purgeable space” that is no longer visible in macOS.
The developers behind DaisyDisk are one of the few to have studied in-depth the new APFS system. Here then is an easy way to fully recover storage space on your Mac including High Sierra, Mojave, Catalina and Big Sur. MacOS will eventually delete them but only in its own sweet time which isn’t convenient if you need that storage space immediately. If you’ve deleted some large files on your Mac and yet still find that it hasn’t freed up any disk space, it’s probably due to these snapshots. Using a disk storage utility like Daisy Disk is now almost essential on macOS because since the release of of macOS 10.13 High Sierra was that, Apple switched to the new APFS file system for Macs with SSD drives.ĪPFS basically balances file space more “intelligently” on your Mac particularly when it comes to Time Machine snapshots and backups.Īlthough APFS can help manage disk space more efficiently, it can also be something of a curse because it actually makes it harder to accurately check storage on your Mac and recover disk space being hogged by local snapshots.

One of the biggest problems users have found after upgrading to macOS Catalina and Big Sur is that their Mac is suddenly running low on disk space.
