Agreed, though I combine using Little Snitch with Radio Silence: https://radiosilenceapp.com Little Snitch is great for when I want hyper granular control of a specific app's network permissions while Radio Silence gives me a super quick way to just block EVERYTHING for a particular app right away without even opening it the first time. - Source: Hacker News / 12 months ago

I'm using radio silence for years and it is awesome :) https://radiosilenceapp.com. - Source: Hacker News / about 1 year ago

Forgot to mention Radio Silence (commercial), seen by many as an easier introduction vs Little Snitch. Source: over 1 year ago

Sorry for the late reply. I use Lulu which should be enough, but I also simultaneously use Radio Silence to be safe. Source: almost 2 years ago

Little Snitch (LS) is considered by many to be the gold standard. The aforementioned Lulu has a good reputation. The app Hands Off! Appears to be no longer developed (site offline). Then there's Radio Silence that may well fit your needs. Finally, one or more apps by Murus may be of interest but AFAIK these are not easy to configure and may be overkill for the average Mac user.

I don’t know who edits the audio feed but chapter markers are very easy to add in most podcast editors (I use this free app to add chapters for my podcasts btw). Source: 12 months ago

To do chapters in MP3 podcasts another tool is needed for the MP3 before publishing such as: https://overcast.fm/forecast. Source: over 1 year ago

Also please add chapters to the audio podcast like you have on YouTube. You can use a free software like this, or depending on your editing software, it might have built in features to do so. Source: over 1 year ago

I saw this a while back, but not used it yet: Https://overcast.fm/forecast. Source: over 1 year ago

Podcasts can change their album art throughout the podcast to show different images. Tools such as Forecast can do this: https://overcast.fm/forecast. Source: over 1 year ago
