title: Mac Intel: zsh: bad CPU type in executable: rustup
body: <p>I had a Mac with an M1 chip which I backed up on an external HDD. I used the backup to setup a Mac with an Intel chip. When I try to rust <code>rustup</code> I get the following:</p>
  <pre><code>$ rustup
  zsh: bad CPU type in executable: rustup
  </code></pre>
  <p>I have tried using the suggestions from <a href="https://stackoverflow.com/questions/72006530/bad-cpu-type-in-executable-mac-intel-core">this</a> answer to no avail.</p>
  <p>For reference:</p>
  <pre><code>$ cat /Users/user/.cargo/config
  [target.aarch64-apple-darwin]
  rustflags = [
    &quot;-C&quot;, &quot;link-arg=-undefined&quot;,
    &quot;-C&quot;, &quot;link-arg=dynamic_lookup&quot;,
  ]
  </code></pre>
  <p>Any suggestions on how to get rust up and running would be highly appreciated.</p>
