A few years ago , Apple settle to offer seamless optimization for computer memory on your Mac . Instead of sleep with where every byte ( or gigabyte ) last , you could enable optimisation in Photos or iCloud Drive . With this feature turn on , your Mac would automatically perform an ongoing trade-off of available disk storage and iCloud warehousing .
presume you have enough iCloud storage , you could have up to 12 TB of information stored in the cloud that is accessible on demand from your Mac , even if you only have a 256 GB SSD . In practice , it ’s more likely you have a 512 GB or 1 TB SSD and 2 TB of iCloud storage , but Apple made both scenarios possible .
As local storage have tight , macOS automatically deletes local copies of file that are synced to iCloud , which apply unseeable surplus storage to ensure that no one drive or Apple data centre would mean the loss of your data . It ’s unknown how tautological iCloud storage is , but it ’s been years since the last reports of data loss of iCloud - stored - only data .
That doesn’t seem to exactly describe my available storage.
If you have iCloud Photos and optimisation enabled , Photos dumps images but retains thumbnail and metadata topically . With Optimize Mac Storage enabled in > System options > Account Name > iCloud , iCloud Drive delete Indian file but leaves stubs you could see and access .
That all vocalize reasonable , but if you start search around the Finder and System preferences , you might get confused . On the desktop , you ’ll see the size of your startup volume and then “ disco biscuit GB devoid . ” But useFile > Get Infowith the volume selected , and there ’s a more detailed explanation : “ useable X GB ( Y GB purgeable ) . ” The first numeral is as reported , but it include file cabinet that macOS could dump in a tweak because they ’re synchronise to iCloud .
That does n’t seem to precisely identify my usable storage .

Where this starts to get more absurd is when you go to > System preferences > General > Storage . At the top , you see a bar that seems to lay out actual information on your inauguration volume , including purgeable data . But scroll down to iCloud Drive , and it shows how much is currently on saucer .
The Storage area shows a breakdown of what ’s apportion .
The Storage area shows a breakdown of what’s allocated.
For me , that amount is listed as 200.1 MB . When I spread iCloud Drive in the Finder and chooseFile > Get Info , macOS report that iCloud Drive has 154,806,040,705 bytes stack away — not abbreviated as 154.81 GB for some reason in the General part – but only 364.7 MB on disk . That latter turn does n’t match the one in Storage .
True , but not as useful as one might hope .
This became an issuing for me late when something went awry when Apple had disruption across iCloud services , admit iCloud Drive . Though it live on in brief , it depend as if my drive suddenly had only 50 GB of actual storage quad uncommitted , an Adobe InDesign book labor refused to lade high - resolution previews from unrelated Dropbox storage ( which is also determine , like iCloud Drive , to purge as necessitate ) , and iCloud decline to allow me select point , Control - click / right wing - click to show the contextual menu , and choose Remove Download to force a purge .
True, but not as useful as one might hope.
Eventually , iCloud take up normal serve , Dropbox catch up , and my simple machine was back to normal . It seems like Apple should have a better way of integrating the amount of usage in macOS into one fascia that helps avoid a full volume . So far , you have to collate across many sources .
