title: Mac OS Sierra install failure: The file couldn't be opened
body: <p>While trying to perform a clean installation of MacOS Sierra on a Macbook Pro 2012 (8Gb ram, 250 SSD Crucial Driver and i5 processor) <strong>through the boot install option (cmd + r)</strong> from the web (Internet install, an this is needed as I just installed the new SSD) the operation always gets stuck at 2 minutes before finishing. </p>
  
  <p>Left it the whole night and in the morning saw the message in the image of this post.</p>
  
  <p>Booted in the new AFP2 filesystem format for the drive as required in the Sierra version. Created the partition and erased the disk without any problem.</p>
  
  <p>Seems the installer is fail fast but not very descriptive, any help would be appreciated otherwise that Mac will likely be a deluxe "cup holder" :(</p>
  
  <p>Thanks a million</p>
