My primary computer is a hackintosh and it's working just fine like a real mac, including little snitch using opencore.

 

Using Hackintoshes for 6 years now. Never had that problem. Sounds like a config issue to me. Which Little Snitch Version are you using, 4? I think you need v3 for El Crapitan. Use Sierra/High Sierra if possible.

Try LuLu as an alternatve to little snitch: https://objective-see.com/products/lulu.html

 

Do you have any good resources for setting up and configuring OpenCore? I'm using clover still. But I've read, OpenCore would be slimmer and faster to boot. But I'mafraid to f'up my boot partition.

 

It's mostly a matter of taste if you use clover or opencore atm, but opencore is definately the future and actively maintained with a great community.
I recommend this to get started:

If you have questions or issues go here:

The unofficial discord channel is here, they helped me a lot getting my opencore up and running:

nothing is free, there is something in it for the app, do some research

 

please tell

 

To be awesome, it would require at least a per-app list of destination addresses and ports. Unfortunately it doesn't have that.
(tcpblock was such an "awesome" free firewall but the developer has stopped its development.)
Update:
Version 2.2.0 of LuLu now supports a blocklist, that's better than nothing.

@5teezo: Technoli on YT does pretty good howto's on Open Core (although the guy has a bit of an irritating voice, but you can't have it all.)
For post install he still uses Clover Configurator, but today I found something new & easier:
