Sync your Desktop and Documents to iCloud
Automatically upload the contents of your Desktop and Documents folders to iCloud Drive so they stay backed up and accessible from other signed-in devices.
How to open Documents & Desktop iCloud Sync
- Open System Settings and click your name at the top (Apple ID)
- Select iCloud, then iCloud Drive
- Enable Desktop & Documents Folders
- Wait for the initial sync to complete
What you should know
- Enabled per-Mac under Apple ID → iCloud → iCloud Drive → Desktop & Documents Folders
- Files move into iCloud Drive but keep the same folder location in Finder
- Frees local space by offloading older files when Optimize Mac Storage is on
- Counts against your overall iCloud storage plan
Why it matters
Syncing Desktop and Documents protects everyday working files from local disk failure and makes them instantly available on any other Mac, iPhone, or iPad signed into the same iCloud account. It's especially valuable for users who frequently switch machines or need a safety net beyond a single local backup. Because it interacts with local storage optimization, understanding this setting is also key to diagnosing why files sometimes show as available only online.
Best practices
- Confirm you have enough iCloud storage before enabling on a Mac with large folders
- Enable on every Mac using the same Apple ID for consistent syncing
- Use Finder's cloud status column to see which files are downloaded locally
- Pair with Time Machine, since iCloud sync isn't a substitute for versioned backup
Common problems and fixes
- Desktop files disappear after enabling on a new Mac
- Wait for the initial sync to complete; files are downloading from iCloud, not lost.
- Running out of iCloud storage
- Upgrade your iCloud+ storage plan or remove large unneeded files from Desktop/Documents.
- Files show a cloud icon instead of opening instantly
- Click the file to trigger download, or ensure a stable internet connection.
Tips and tricks
- Use Finder's 'Remove Download' option to free local space on files you don't need offline
- Check sync status in the iCloud Drive area of System Settings if uploads seem stalled
Frequently asked questions
Does this replace Time Machine backups?
No, iCloud sync keeps one current copy in the cloud but doesn't provide the version history Time Machine offers.
What happens if I turn it off?
macOS asks whether to keep a local copy of everything or keep only files stored in iCloud Drive.
Does this work with an external Documents folder?
No, it only syncs the default user-level Desktop and Documents folders.
