MacOS LuLu Blocklist?

Is there any blocklist of MacOS Apple system agents and processes to be used in outgoing firewalls? I am using LuLu at the moment and have implemented the blocking recommendations from Michael Bazell’s Extreme Privacy (latest edition), although he was using Little Snitch.

I was wondering if there is a resource or if anyone can tell me what system processes, agents and daemons can be blocked without nerfing system functionality? I pretty much only want new system updates and don’t care for any of the Mac apps or Apple ID.

If not would shelling out 60 Dollars for Little Snitch be a better idea?

Guidance would be very much appreciated!

I haven’t used LuLu, but I think this Techlore discussion would help.

If you’re able to use Little Snitch filter lists, Ph00lt0 from PG has one.

Alright thank you for this!
