Greetings - Looking for a recommendation for a good filter for MacOs. Recognize there is no perfect solution - had been using K9 a while back but unfortunately I was going around it.

Thanks!

I am using a combination of K9 and the "SelfControl" app and so far it is working for me thank god. With SelfControl you can completely block access to the internet for up to 24 hours, this way K9 does the initial filtering and when you feel your defences lowering down you can take an action of recovery by blocking your access to the internet. Hope this helps, wishing you a serene and sober day.

I use OpenDNS at home.  www.opendns.com/home-internet-security/  They have free services and the paid services are about $20.00 per year.  It's configured on your router, so any device connected to your router is automatically included.  

I have been very happy with it.  

Sounds interesting.
How is it different to internal device  filtering?

Looks like it will refuse to look up the IP address for names on its blacklist.

It's a proxy service.  All internet traffic is directed through their servers, and known bad addresses are blocked.  The big difference between this and device based applications are:
1. There is no local application. Nothing on the machine that can be paused or bypassed.
2. The service is configurable. It can block various types of traffic including malicious websites as well as adult websites.
There are 2 ways to set it up. I prefer setting it up on the router.  But, it can be configured locally on each machine and on mobile devices as well.

Watch out because a proxy really stops your requests under all circumstances. But a DNS server is easy to get around.

I'm deliberately not saying how because I don't want to mess things up for people who are content with using DNS lookup to "filter" the internet.
