Hello All!

I've been a happy owner of the rMB 2015 (1.2MHz) for almost 6 weeks now. Although it hasn't really affected me, I noticed a strange random behavior when I start the machine up. It has happened 3 or 4 times during this period and I was wondering what may be causing it.

Sometimes, when I press the power button, I see the Apple logo and hear the chime. At this point, the screen gets black and the machine restarts. At first I didn't think much of it, but on the second time, I noticed that after the "second start", the startup screen was diferente in two ways:

1) Guest user account did not show;
2) The wallpaper (that you can see through the transluscid pattern of the startup screen), was reverted to the default one.

I can proceed with the login normaly and get the progression bar. After that, the machine Works perfectely and once the startup process is completed, I get my choosen wallpaper back.

I thought the problem could be related to the Guest User account, so I disabled it. Unfortunatelly, today I got the problem again. I don't know how, but eventually it cames back to normal, after I reboot a couple of times and or logout and login back to my account.

Any ideas what could be causing it? Thanks in advance for your thoughts!
