  <p>Brew is trying to install openssl 1.1.1l:</p>
  <pre><code>==&gt; Downloading https://www.openssl.org/source/openssl-1.1.1l.tar.gz
  Already downloaded: /Users/user/Library/Caches/Homebrew/downloads/b6ccc5a2a602c2af3480bbcf1656bd9844595974ba60501871ac12504508e818--openssl-1.1.1l.tar.gz
  </code></pre>
  <p>I need this dependency to install many other applications/tools, e.g., wget or python - and would like to use homebrew to do this.</p>
  <p>The brew version I am using is:</p>
  <pre><code>Homebrew 3.2.9
  Homebrew/homebrew-core (git revision fa395c6627; last commit 2021-08-27)
  Homebrew/homebrew-cask (git revision 606ed52390; last commit 2021-08-27)

  <p>macOS is: 10.12.6 (Sierra) and I am using a MacBook Pro (13-inch, Early 2011)</p>
  <p>Is there any way I can get around this issue to install openssl? Or anyway I can install python specifying a different openssl to use as a dependency?</p>
  <p>I was able to install openssl 1.0 using the following brew command:</p>
  <pre><code>brew install rbenv/tap/openssl@1.0
  </code></pre>
  <p>However, python continually tries to use openssl 1.1.1l which is failing with the above error.</p>
