Homebrew 1.4.0
&gt; <i>Homebrew requires the CLT on all but the latest version of macOS (to avoid copious workarounds in formulae)</i><p>Why? What are these workarounds? The linked PR didn&#x27;t explain, and as someone who&#x27;s still got one machine on 10.12 I&#x27;d really rather not have to keep CLT installed as well.<p>Edit: Wow, the maintainer on that PR is a real jerk. He refused to answer a legitimate question (and locked the PR at the same time) because he thought the original (since edited) complaint of &quot;The error message for this patch is terrible&quot; was &quot;rude&quot;.<p>MikeMcQuaid, if you ever read this, this sort of behavior on your part is a great argument for ditching HomeBrew.
