How to Free Up iCloud Drive Space on Mac

If you want to free up iCloud Drive space on Mac, start by separating two issues: your iCloud storage quota, and the local disk space used by files downloaded on the Mac. Clean the wrong one, and you can spend time deleting files without fixing the warning you actually see.

This guide explains both sides: what counts against iCloud storage, what still lives on your SSD, which files are usually worth removing first, and how NythyCleaner can scan the local iCloud Drive tree safely. For broader storage cleanup, read how to free up disk space on Mac.

Why iCloud Drive Space Disappears

Several things add up over time:

Photos and videos synced through iCloud Photos (counted against your iCloud storage, not only “iCloud Drive” in the label).
Desktop & Documents if you use the feature that stores those folders in iCloud — every file there counts toward the quota.
Old versions and duplicates — the same project copied in multiple folders, or archives you forgot to delete.
App data that apps store inside iCloud Drive (documents packages, databases, exports).
Local copies on your Mac that still occupy disk space even when files are also in the cloud.

Understanding the split between cloud quota (what Apple shows in System Settings) and local disk usage (what Finder shows on your volume) helps you choose the right fix.

Step 1: See What Apple Reports

On macOS Ventura or later:

Open System Settings.
Click your Apple ID name at the top.
Choose iCloud, then Manage (or Manage Account Storage).

You will see categories such as iCloud Drive, Photos, Backup, and Mail. Note which category is largest — that is your first cleanup target.

💡

If you only need to free local disk space on the Mac while keeping everything in iCloud, use Optimize Mac Storage (Apple ID → iCloud → iCloud Drive → Options) so older files stay in the cloud until you open them.

Step 2: Clean Up Manually in Finder

Remove large or obsolete files

Open Finder and click iCloud Drive in the sidebar (or go to your user folder and open iCloud Drive).
Switch to List view and click the Size column to sort by size.
Delete installers (.dmg, .pkg), duplicate downloads, and old project folders you no longer need.
Empty Trash so the space is actually reclaimed.

Check Desktop and Documents

If Desktop & Documents Folders is enabled for iCloud, heavy files on the Desktop count toward iCloud. Move archives to an external disk or delete what you do not need.

Advanced: the on-disk path

Your Mac stores iCloud Drive files under a hidden-ish path (one of):

~/Library/Mobile Documents/com~apple~CloudDocs

Power users can inspect this folder in Finder (Go → Go to Folder…) to see exactly what is using space. Be careful: deleting the wrong item can break app data that expects a specific layout.

Step 3: Use NythyCleaner to Scan iCloud Drive

NythyCleaner includes a dedicated iCloud Drive section that scans the local iCloud Drive root (com~apple~CloudDocs), lists candidates for cleanup, and helps you act without hunting through every subfolder.

Typical workflow:

Open NythyCleaner and go to the iCloud Drive section.
Run a scan — the app walks the tree and surfaces files you can review.
From the list, you can move items to the Trash, remove files when allowed, or evict the local copy when you want to keep the file in iCloud but free space on the Mac (when applicable).

ℹ️

NythyCleaner focuses on safe, explicit actions. Folders may be restricted from deletion in this list when the location is not allowed — prefer cleaning files rather than deleting complex folder hierarchies you do not fully recognize.

This complements the rest of the app: Disk Space for a full-volume treemap, System Cleanup for caches and clutter, and other tools for duplicates and maintenance — so you can tackle both iCloud quota and local SSD pressure in one place.

Step 4: Reduce Future Growth

Unsubscribe from large shared folders you no longer need.
Export and archive finished projects to cold storage instead of leaving them in iCloud forever.
Review Photo Library settings if Photos dominates your usage — consider local archives or a higher tier only when needed.

Conclusion

Freeing iCloud Drive space is part discipline (delete what you do not need) and part visibility (know which folders and files dominate). Apple’s storage panel shows the big picture; Finder and Optimize Mac Storage handle the basics on disk. For a fast, structured pass over your local iCloud Drive tree, NythyCleaner’s iCloud Drive scan turns a vague “sync full” problem into a clear list of actions — so you can reclaim space without guesswork.
