File Provider check service · seed · quit hint: caution
FPCKService is a macOS process (listed here as File Provider check service) — also matched as com.apple.FileProviderDaemon.FPCKService. People usually find it in Activity Monitor when asking “what is this process?”
What does FPCKService do?
FPCKService is an XPC service inside FileProviderDaemon that runs File Provider checks (FPCK)—integrity/consistency maintenance for cloud file domains such as iCloud Drive and third-party File Providers. fileproviderd / fileproviderctl start it when a domain check or repair is needed. You need it for those maintenance jobs; quitting aborts an in-flight check until the service relaunches—prefer waiting out high CPU rather than killing it during sync repairs.
