Optimised Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, films, email attachments and other files that you rarely use are stored in iCloud automatically. Each file stays exactly where you last saved it, and will download when you open it. Files that you’ve used recently remain on your Mac, along with optimised versions of your photos.
* If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps may show storage categories, such as Not Mounted, VM, Recovery, Other Volumes, Free or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file only frees up the space required by any data that you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
- If you're using a pro app and Optimise Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.
The Collector
You can tear off DaisyDisk’s petals and drop them to the special area at the bottom called Collector
:
In addition to drag-and-drop, you can put files and folders to the Collector by selecting the Move Selected File
to Collector command from the item’s context menu, or by pressing ⌘⌫ hotkey while pointing to an object.
Remove Purgeable Mac Os
Don’t worry, the files remain intact until you click the button.
You can expand the Collector by clicking on it to make sure you are not about to accidentally delete some needed files. The expanded Collector works just like the sidebar, so you can preview files and drag them out. Another way to get an item out of the Collector is to point and click the button near its name
What can you delete?
Some folders like /System, /Library or current user’s home folder are not meant to be deleted, so the Collector will not accept them.
Semi-transparent (consolidated) petals also cannot be removed, you’ll have to expand the group and drag individual files and folders.
Clicking the button starts deletion process, but you’ll have 5 seconds to change your mind and press .
DaisyDisk permanently removes files and folders instead of moving them to the system Trash, so that the disk space is actually recovered. These files cannot be undeleted
, but there are other ways.
Free space not appearing after deletion?
Contrary to what you may expect, deleting files in macOS may not immediately produce free space. If Time Machine is enabled on your Mac (which should always be recommended), it will regularly back up your entire disk’s content in so called local snapshots. The snapshots are designed in such a way that they don’t consume additional disk space if there is little change compared to the previous backup.
So, when you delete a file, its copy may still be retained in the local snapshots, and still consume the same amount of disk space. In result, the free space will not grow, but the amount of hidden space, and more specifically, the purgeable space, will increase by the corresponding amount. This is normal — macOS will eventually automatically reclaim the purgeable space when the apps request more disk space. Alternatively, you can forcedly purge it with DaisyDisk.
