title: How to enable navigator.hardwareConcurrency in Safari?
body: <p>For my model I need to enable navigator.hardwareConcurrency for Safari browser so that I can get to see how many virtual core a client has.</p>
  
  <p>I found following statement on canIuse.com, but still do not know how to enable, and it's kind of vague to me how to enable this.</p>
  
  <p><code>WebKit browsers clamp the maximum value returned to 2 on iOS devices and 8 on all others. Disabled in Safari behind the ENABLE_NAVIGATOR_HWCONCURRENCY build option.</code></p>
  
  <p>Cheers!!</p>
