I've been trying to harden my OSX 10.11 computer and one of the guides suggested installing Homebrew to get updates to things such as OpenSSL. While updates are great, it seems like Apple should be relatively on top of issues (a recent web test showed TLS 1.2 installed...), along with having a comprehensively tested system OS.
Would Homebrew +package updates have an additive effect with Apple security updates? Does Homebrew have known security issues in and of itself? Or would installing a package manager and associated updates change the system configuration such that, in the hands of a relatively inexperienced admin, it will ultimately be in a more vulnerable state?
