Short answer

Part of macOS. findmydeviced runs Find My Mac. searchpartyd is another Find My daemon that Apple doesn't describe in its man page.

Block with care

Blocking them can stop Find My from locating this Mac. Keep Find My on if you want to find a lost or stolen Mac.

Path: /usr/libexec/findmydeviced /usr/libexec/searchpartyd
launchd label: com.apple.icloud.findmydeviced com.apple.icloud.searchpartyd
Signing identifier: com.apple.icloud.findmydeviced com.apple.icloud.searchpartyd

What it is

The man page says: “findmydeviced is the daemon for Find My Mac.” It has no options.

The searchpartyd man page says only that it is a daemon, with no configuration options. Both run from /usr/libexec with launchd labels under com.apple.icloud.

Apple Platform Security says that an online device reports its location to the owner through iCloud. Find My also works offline. A missing device sends Bluetooth signals that nearby Apple devices relay to iCloud, end-to-end encrypted.

Why it uses the network

Find My Mac. To show the Mac in Find My, the Mac reports to Apple through iCloud.
Offline finding. Apple says that any Mac with offline finding on can act as a finder device. It reports an approximate, encrypted location of nearby missing devices to iCloud.

How much is normal

With Find My Mac on, the traffic is small.

Apple says that the traffic from finder devices carries no authentication information. Apple doesn't know who found a device or whose device was found.

Apple doesn't document searchpartyd's own network use. Measure it with the steps below.

When it uses a lot, and why

Not documented as heavy. Apple documents no large transfers for Find My. Location reports and relays are small.

Is it safe to block?

Block with care

Blocking them can stop Find My from locating this Mac. Keep Find My on if you want to find a lost or stolen Mac.

What breaks if you block it

Find My may not show this Mac's location, so a lost or stolen Mac is harder to find.
This Mac may stop helping to find other people's missing devices.
Apple doesn't document all of searchpartyd's work, so other Find My features may be affected.

Blocking means a firewall rule that refuses its connections. Don’t quit or disable a macOS process to save data: macOS starts it again, and other features depend on it.

Reduce its use

Keep Find My Mac on. It helps you find a lost or stolen Mac.
To turn it off, choose Apple menu › System Settings. Click your name, then iCloud.
Click See All, click Find My Mac, then click Turn Off. Apple says that this also removes Activation Lock.
Don't quit these daemons in Activity Monitor. macOS starts them again.

Through MCP, an AI agent asks explain_connection with the process name. It gets the same facts.

The live view and the explanations are free. History in the app needs Kilobat Pro. Blocking needs Pro and the network filter: see the network filter, Protection and the hotspot data saver.

What isn’t documented

The searchpartyd man page doesn't say what it does. Apple Platform Security describes Find My, but doesn't name the daemons.

Questions

Does Find My need Location Services?

Yes. Apple's guide says that Find My Mac needs Location Services.

Can someone track me through offline finding?

Apple says that the broadcast key changes about every 15 minutes, so a device can't be followed by a fixed identifier.
