Why can't I delete some system files, even as an administrator?

\n

Short answer: System Integrity Protection and the sealed system volume stop anyone, including admins, changing macOS files. Reclaimable space is in your files, apps, caches and backups instead.

\n

macOS protects its own files with System Integrity Protection and a sealed, read-only system volume, so even an administrator can't delete or change them. That protects your Mac from malware and accidents.

\n

Those protected files aren't what fills a disk anyway — the space you can reclaim is in your own files, apps and their data, caches, snapshots and backups. Disabling these protections to delete system files is not recommended.
