Can I delete CloudKit cache on Mac?

Yes — safe to remove

Nothing here is the only copy. macOS puts it back on its own.

The right way to clear it

  1. Quit the app completely (⌘+Q in the menu bar).
  2. Open Finder and press ⌘+Shift+G to open "Go to Folder".
  3. Paste this path and press Enter:
    ~/Library/Caches/CloudKit
  4. Select the files you no longer need and move them to Trash. Empty Trash to reclaim the space.

Let OptiClear find these files

Doing this by hand is slow and easy to get wrong. OptiClear scans your Mac, lists every related file with its size, and moves only what you select to the Trash, so you can still restore it. Scanning is free; cleaning requires OptiClear Pro.

Frequently asked questions

Is it safe to delete CloudKit cache?
Yes, once the apps using it are quit. It holds derived data, not originals, so macOS rebuilds whatever it still needs.
Why is CloudKit cache so large?
It grows with use and macOS puts no ceiling on it. 500 MB – 10 GB is normal on a Mac that has been in service a while — the detail guide breaks down what fills it.
