Apple’s iCloud is handy in that it lets you have access to your
files on multiple devices that have internet access. But what’s
actually stored in iCloud isn’t that obvious to the user.
This seems to be the case for Macworld reader Izabella. She
asks why iCloud isn’t reducing storage on her MacBook more than
it is. She sees iCloud storage on her computer taking up 80GB
of storage but says she’s paying for 200GB of iCloud storage.
“I want to use this space for other things,” she notes.
iCloud doesn’t necessarily save you storage, as confusing as
that is, because it’s a mix of synchronization and cloud-based
iCloud Photo Library syncs all your photos and videos, but
unless you set Photos (in Photos > Preferences >
iCloud to Optimize Mac Storage), the full-resolution file
for each piece of media remains on your Mac. Check that
box, and you could save 80 to 90 percent of a library’s
iCloud Music Library also syncs music, but lets you keep
local files unless you take action. You can select songs or
albums and Control-click to select Remove Download, which
deletes locally stored files and leaves the backups in
iCloud. (Be sure you have a backup of your music files
before you do this! Things can go wrong.) If you want to
know which songs are only in the cloud, create a Smart
Playlist with the criteria Location Is Not On This
iCloud Drive is always synced: a copy is always on your
computer and in iCloud for everything listed except for the
Desktop & Documents is an option (introduced in macOS 10.12
Sierra) to shift and sync less-used files from those two
Home folder locations to the cloud, and only download them
locally as needed. You can access that option via >
About This Mac > Storage and click Manage (or via
Applications/Utilities/System Information, and choose
Window > Storage Mananagement), and then click Store in
iCloud. You want a high-speed broadband connection for the
times you need macOS to retrieve those files.
iTunes purchases. Also in the storage manage tab of System
Information, you can opt to delete what can turn out to be
gigabytes of downloaded media that remains available for
retrieval or streaming on demand from the iTunes Store.
Making a few changes could free up tens to hundreds of
gigabytes of storage, depending on the amount of media and
kinds of documents you store on your Mac.
A warning, though: you’re relying on iCloud and Apple to keep
all that data safe for you. I’d rather have more storage on my
computer, keep all the iCloud items copied from and to my main
Mac, and separately clone and archive all those files myself in
addition to iCloud.
