I have a problem with my MacBook Pro, which runs Mac OS X Lion. I have reseted it back to the Setup Assistant. After I executed the following commands, I need to select the region when I boot; this works fine, but when I choose the keyboard, the whole Mac gets stuck, and I see the loading icon on the screen. Even if I wait one hour, nothing happens. Code: $ mount -uw / $ rm -R /Library/Preferences/ $ rm -R /Users/username/ $ rm /var/db/dslocal/nodes/Default/users/username.plist $ rm /var/db/.AppleSetupDone How can I solve this? Actually, I have no Mac OS X disc to reinstall it. can I create a user via the command line, or skip the setup assistant?
