Hi, I'm running osx 10.6.8 on a mac mini trying to install the dmg file to the usb using the restore.pkg file. It starts installing then displays "The installation failed" each time. I had the same problem when trying to install 10.8.2. I never resolved that and decided to move onto 10.8.5. To be clear; I have OSX-10.8.5.dmg and OSX-10.8.5 Restore.pkg in a folder together and a 16GB usb drive selected. The usb drive is not formatted (got stuff on there) but its gonna wipe it anyway (which I'm fine with). I run the .pkg file in the folder. Any ideas would be appreciated. Thanks.
