Hi all,



I'm using the "Son of InstallLion.pkg" utility (found at http://managingosx.wordpress.com/2012/07/25/son-of-installlion-pkg/) to create an installer package that will upgrade a user's computer to 10.8. The package itself runs just fine, but when I create a policy to install the package, nothing happens. The Casper logs say that it was installed successfully, but when the computer restarts, the OS has been left untouched.



Log says:

Any ideas?

When you tell it to restart, make sure you specify "Currently Selected Startup Disk (No Bless)". That's what fixed it for me.

@alex.merenyi - That did the trick. Thanks! I didn't even know about those options.

If Casper changes the blessed startup disk before rebooting, that would indeed cause the OS X install process to fail.
