<p>Running <code>sim setup-silent</code> on a freshly updates macOS BigSur x86 VM I get:</p>
<div class="codehilite"><pre><span></span><span class="c">% ./simfactory/bin/sim whoami</span>
<span class="n">Error</span><span class="p">:</span> <span class="n">value</span> <span class="k">for</span> <span class="n">key</span> <span class="n">ppn</span> <span class="n">in</span> <span class="n">section</span> <span class="n">osx</span><span class="o">-</span><span class="n">homebrew</span> <span class="n">is</span> <span class="n">not</span> <span class="n">of</span> <span class="n">required</span> <span class="n">type</span> <span class="n">int</span>
<span class="n">Aborting </span><span class="s">Simfactory.</span><span class="p"></span>
</pre></div>
<p>On that system python3 happens to be Python 3.8.2.</p>
<p>This can be fixed by:</p>
<div class="codehilite"><pre><span></span><span class="gh">diff --git a/lib/simdt.py b/lib/simdt.py</span>
<span class="gh">index 6b51053f..c1a63cea 100644</span>
<span class="gd">--- a/lib/simdt.py</span>
<span class="gi">+++ b/lib/simdt.py</span>
<span class="gu">@@ -528,7 +528,7 @@ class DecisionTree:</span>
# Throughout, we ignore hyperthreading. That can be added later.
if platform.system()== 'Darwin':
SocketsPerNode = int(cpu_info['hw.packages'])
<span class="gd">- CoresPerSocket = int(cpu_info['hw.physicalcpu']) / SocketsPerNode</span>
<span class="gi">+ CoresPerSocket = int(cpu_info['hw.physicalcpu']) // SocketsPerNode</span>
else:
CoresPerSocket = int(cpu_info['Core(s) per socket'])
SocketsPerNode = int(cpu_info['Socket(s)'])
</pre></div>
<p>which should be backported.</p>
