tptacek's criticisms are quite valid. However, "it's not good" seems oversimplified to me? I found lots of interesting information in this.

For example: information about the activation process for Macs, importance of setting a firmware password, disable some of the Spotlight services, and binary whitelisting through Santa. The repo also has the most comprehensive discussion I've seen about evicting FileVault keys from RAM on sleep: https://github.com/drduh/macOS-Security-and-Privacy-Guide/is...

Also, I'm not sure if this has been changed more recently than the comment you linked, but it seems like they actually don't recommend AV software anymore: "Therefore, the best anti-virus is Common Sense 2020. See discussion in issue #44."

I grant you that having someone follow this top to bottom might be bad, but to say "it's not good" seems to both lack nuance and also to discard some useful, hard work done in good faith.

A guide that can't be used safely by non-specialists while being aimed at them is not a good guide. It is a very simple conclusion with the added benefit of also being almost tautologically true.

The thing probably does contain a bunch of interesting information but it's not good at its stated purpose.
