Seriously, It's a beta, what did you expect.
Sometimes they work and sometimes they don't.
You roll with the punches and move on

1. Download MacOS Sierra torrent & open the .dmg
2. Right-click the .app - "Show Package Contents"
3. Open (mount) InstallESD.dmg, located along the path of "Install ...app / Contents / SharedSupport /"
4. From the contents of the OS X Install ESD open (mount) BaseSystem.dmg (default BaseSystem.dmg Basesystem.chunklist and hidden. Use the utility "ShowAllFiles").
5. Run Disk Utility and expand BaseSystem.dmg on the flash drive formatted GUID (the "Options") and Mac OS coffee (HFS +)
6. Copy the folder OS X Install ESD / Packages folder on the flash drive in the / System / Installation / replacing the file alias Packages.
6. Copy to the root of the stick and BaseSystem.dmg Basesystem.chunklist of Install ESD
If you do not - get an error Undefined error: 0 at the very beginning of the installation!
7. Backup
8. Reboot while holding down Alt. Choosing our stick. If necessary, after Disk Utility to erase partitions. We put the system.
9. Now you can install macOS Sierra on your Macs.

You can also drag the .app into the Application map.

Yes you get a app store notification on your Mac.

How is babby made?

If it's installed open the .dmg and you can drag the .app into the Application folder. (It's the real macOS Sierra)
