System-wide caches, logs, updates, applications, and support data can serve more than one user.
Before removal, confirm no other user is signed in with active work and no update, backup, export, or installation is running.
Preserve diagnostics needed by another user or administrator. Coordinate application removal and shared-container cleanup.
Approve administrator authorization only for the reviewed target.
On organization-managed Macs, follow retention and maintenance policy. A local administrator password does not replace authorization to delete organizational data.
