Blocked Internet access to MacOS daemons & agents

Here is a list of some MacOS daemons and agents which have been trying to access the internet, and which I have now blocked in my firewall.

Many of the services were trying to access the internet, even when the respective app was not in use, and even when the services were explicitly disabled in System preferences. for eg. Stocks, News, Weather, Notes, iCloud, iTunes, Wallet, Home Kit, No ad preserving measurement required, etc.

Some of these daemons are for support for connected iOS devices. I don’t use iPhone/iPad so they were irrelevant for me.

Do comment if

  • you believe some of these services are critical and should be allowed Internet access.
  • Have clarity on the purpose of each or any of these daemons? Very limited information is available on Internet.
  • Have you ever monitored on your Macs, how many Apple services randomly and regularly connect home? and what data do they share back?

Try the Lulu firewall or Little Snitch. Uncheck Allow Apple Programs, Uncheck Allow Installed Programs. This will give you a fair idea of the services which try to access the internet from the moment you log in.

My Mac still works fine. No critical functionality seems to be affected, yet.

These are some of the daemons & agents which currently do have access to the internet, and I am not sure on the purpose of some of them to connect to the Internet.

Do share, if you have any info on these, their purpose or whether they can be safely blocked from accessing the Internet.

Won’t blocking appstoreagent stop you from getting automatic updates for your App Store apps?

u r right, fixed it.

Insight on a few of the processes you’re not sure about:

  • captiveagent detects captive portals on wi-fi networks so they can be properly accessed and logged into.
  • apsd is for push notifications.
  • trustd verifies the validity of digital certificates.
  • mDNSresponder is necessary for local discovery features like AirDrop, I believe.

I have had the following blocked for over a year with no issues:

  • AssetCacheLocatorService
  • helpd
  • studentd

It sounds like you may have widgets for those apps in Notification Centre. Spotlight can also retrieve information from those services and can be disable in system settings.
Currently, there is no explicit way to remove native apps in macOS.

It might be because you have AirDrop or Handoff. You can disable AirDrop and Handoff in system settings.
