Can't nobody really help me? I've reinstalled Lion and restored backup after that and the problem still persists: The machine, after clicking the power button to turn off and on again, doesn't boot in the first but boots in the second attempt. I then reboot for some update or whatever and the system doesn't boot at the third but boots in the second.
Again, fixing the disk and disk permissions aren't helping me.
What can I do? It's really annoying to boot the Mac, shut it down manually and boot it again everytime I want to use it.
