title: Emulator: Warning: Quick Boot / Snapshots not supported on this machine
body: <p>I am starting to learn android but havent been able to get anywhere. I downloaded android studio as per instructions and im trying to set up an AVD.
  I am using a Mac Air(macOS High Sierra) with java 1.8.0_51.  </p>
  
  <p>The moment i launch an AVD there is a warning in the event log: 
  "Emulator: Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release." </p>
  
  <p>The emulator just gets stuck on the loading page. </p>
  
  <p>So far i have tried to :
  1. Reduce AVD Ram size
  2. Increase AVD heap size
  3. change to "software" to avoid issues if any with my graphics card
  4. Install/ delete many versions of phones/api levels for avd</p>
  
  <p>In the Logcat logs i see the following errors:</p>
  
  <blockquote>
    <p>03-09 17:27:15.544 0-1114/? I/lowmemorykiller: No kernel
    memory.pressure_level support (errno=2) 03-09 17:27:15.545 0-1114/?
    E/lowmemorykiller: Kernel does not support memory pressure events or
    in-kernel low memory killer</p>
