Is there a better way to shutdown/restart OSX?
If you don't care about saving the session, you can simply hit Ctrl + Option + ⌘ + ⏏ for Shutdown or Ctrl + ⌘ + ⏏ for Restart

You can also check out this post (Disable "Reopen Windows") on disabling resume if you don't want that. There is another solution posted here on Apple's forums for disabling the feature by William Donelson (second post by him on the page).
