# What's the difference between "iCloud storage is full" and "Mac storage is full"?

They're two separate pools of space. **iCloud storage** is the space in your Apple Account online, shared by your photos, iCloud Drive, device backups, Mail and messages. **Mac storage** is your Mac's own disk. Filling one doesn't fill the other, and freeing one doesn't free the other.

- "iCloud storage is full" — fix it in iCloud: delete or move things out of iCloud, or change your plan. See [what to do when iCloud is full](https://storagestudio.us/faq/icloud/my-icloud-storage-is-full-what-can-i-do).
- "Mac storage is full" — free space on the Mac: clear caches, make cloud files online-only, move big items to an external drive.

They interact in one way: with **Optimize Mac Storage**, iCloud keeps files online to save Mac space — but that needs iCloud space to hold them. Storage Studio works on the Mac side; it never deletes from your iCloud account.
