    1. Downloaded Install macOS Sierra.app countless times. Finally gave up on wireless and used a wired connection.
    2. After much research and reading, unless I missed something, decided to create a new topic for an old issue:
    3. Attempted to provided requested debugging information, unfortunately, when reviewing /var/log/install log, I did not find either of the following two strings: "Install: "UniBeast Mac App Store"" or Displaying 'Install Failed' UI.
    4. Please see attached images - Is this a catch-22 ?

    Kept downloading Install macOS Sierra.app until checksum of InstallESD was good.

    Thanks

    I had the same issue that I couldn't mount InstallESD when creating a sierra UniBeast Drive. After much searching I found a reference to MTU frame sizes. I worked out my optimum MTU setting (plenty online how to do this) and set it in the Network settings on OSX. I then re downloaded the Sierra Install. I then ran Unibeast again and it worked perfectly first time. Given that I haven't had issues with downloads before this surprised me but it clearly impacts these larger file downloads.

    Thank you.
    the solution was to reboot my Mac Air....
    once rebooted the installation started.
    Thank you again
