I burned out on Little Snitch. I lasted about 5 years, but I find the constant breakage and allowlisting to be really fatiguing when I just want to work.
For the security conscious, there is also Google Santa, but again, there is a lot of configuration to use it. I lost a year of my life to Arch Linux back in the day. No one saw me - I don’t really remember what happened - I just remember a lot of blinking when I first saw the sun again… I think about 6 months of that time was spent trying to center my desktop wallpaper image. Which is my way of saying that, if you went with macOS because you just want things to work without tinkering, these additional layers of security can really rob you of that feeling. What’s challenging for me as a non-security-professional is really quantifying risk. If you have no idea how vulnerable you are, it’s difficult to decide how much effort one should expend in this arena.
