Clean install - same thing twice??

[quaresma]

Hi guys. I'm in the process of clean installing 10.11.4. The installation went fine and installed in 15 min. and rebootet automatically.

But now it's installing again on the boot screen?? It's been 25 minutes now.

It has happened before when clean installing Mavericks and EC.

But when clean installing 10.11.3 it booted into OS X right after the auto reboot after installation.

It's like its random. Some times The installation is fast and sometimes when finishing The installation it will reboot and Do an installation on The boot screen with Black background and loading bar.

Is it doing The same thing twice??

Depending on what model Mac you are installing this on, there an be a firmware update installed along with 10.11.4 and this does look a little like another OS update. It has a similar progress bar as the firmware update installs, then it restarts and you see the OS install. Could that be what you are seeing.
