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

\n

Short answer: They're separate: iCloud storage is your online Apple Account space (photos, Drive, backups, Mail); Mac storage is your Mac's disk. Freeing one doesn't free the other. Fix iCloud full in iCloud; fix Mac full on the Mac — Storage Studio works on the Mac side.
