A couple of years in the past, Apple determined to supply seamless optimization for storage in your Mac. As a substitute of understanding the place each byte (or gigabyte) lived, you can allow optimization in Images or iCloud Drive. With this function turned on, your Mac would robotically carry out an ongoing tradeoff of obtainable disk storage and iCloud storage.
Presuming you might have sufficient iCloud storage, you can have as much as 12TB of knowledge saved within the cloud that’s accessible on demand out of your Mac, even if you happen to solely have a 256GB SSD. In observe, it’s extra possible you might have a 512GB or 1TB SSD and 2TB of iCloud storage, however Apple made each eventualities doable.
As native storage will get tight, macOS robotically deletes native copies of recordsdata which are synced to iCloud, which makes use of invisible redundant storage to make sure that nobody drive or Apple information middle would imply the lack of your information. It’s unknown how redundant iCloud storage is, nevertheless it’s been years for the reason that final stories of knowledge lack of iCloud-stored-only information.
When you have iCloud Images and optimization enabled, Images dumps photographs however retains thumbnails and metadata domestically. With Optimize Mac Storage enabled in > System Settings > Account Identify > iCloud, iCloud Drive deletes recordsdata however leaves stubs you’ll be able to see and entry.
That each one sounds cheap, however if you happen to begin wanting across the Finder and System Settings, you would possibly get confused. On the desktop, you’ll see the scale of your startup quantity after which “X GB free.” However use File > Get Data with the quantity chosen, and there’s a extra elaborate clarification: “Available X GB (Y GB purgeable).” The primary quantity is as reported, nevertheless it contains recordsdata that macOS may dump in a pinch as a result of they’re synced to iCloud.

The place this begins to get extra absurd is while you go to > System Settings > Common > Storage. On the high, you see a bar that appears to characterize precise information in your startup quantity, together with purgeable information. However scroll all the way down to iCloud Drive, and it reveals how a lot is presently on disk.
The Storage space reveals a breakdown of what’s allotted.

For me, that quantity is listed as 200.1MB. After I open iCloud Drive within the Finder and select File > Get Data, macOS stories that iCloud Drive has 154,806,040,705 bytes saved—not abbreviated as 154.81GB for some motive within the Common part–however solely 364.7 MB on disk. That latter quantity doesn’t match the one in Storage.
True, however not as helpful as one would possibly hope.

This grew to become a problem for me lately when one thing went awry when Apple had disruption throughout iCloud companies, together with iCloud Drive. Although it lasted briefly, it regarded as if my drive all of a sudden had solely 50GB of precise space for storing out there, an Adobe InDesign e-book mission refused to load high-resolution previews from unrelated Dropbox storage (which can also be set, like iCloud Drive, to purge as wanted), and iCloud refused to let me choose objects, Management-click/right-click to indicate the contextual menu, and select Take away Obtain to power a purge.
Finally, iCloud resumed regular service, Dropbox caught up, and my machine was again to regular. It looks like Apple ought to have a greater means of integrating the quantity of utilization in macOS into one dashboard that helps keep away from a full quantity. Thus far, it’s a must to collate throughout many sources.
