title: Intel X86 emulator accelerator (HAXM installer) VT/NX not enabled
body: <p>I`m asking how to enable my VT/NX for my MacBook, when I try to use X86 emulator, it appears to me that VT/NX NOT ENABLED, it had never seem this when I used 10.9 system, after I update my MacBook to Yosemite, it appears to me.</p>
  
  <p>When I try to start my x86 emulator, it tells me:</p>
  
  <pre><code>Starting emulator for AVD 'X86'
  emulator: ERROR: x86 emulation currently requires hardware acceleration!
  Please ensure Intel HAXM is properly installed and usable.
  CPU acceleration status: HAX is not installed on this machine (/dev/HAX is missing).
  </code></pre>
  
  <p>But the AVD shows me that I had installed HAXM.</p>
  
  <p>When I try to install by myself again, installer prints <code>VT/NX NOT ENABLED</code>.</p>
  
  <p>I can not post any images…</p>
  
  <p><strong>to mindex's answer:</strong></p>
  
  <p>I tried running all versions of Intel HAXM I could get:</p>
  
  <pre><code>IntelHAXM_1.0.8.dmg     
  IntelHAXM_1.1.0_for_10.10.dmg     
  IntelHAXM_1.1.0_below_10.10.dmg      
  </code></pre>
  
  <p>But it did not work.</p>
