White screen at boot
Every now and then, i get a white screen, that seems to cover up the users login page. This occurs just before the Apple logo and the Chime sound. Normally when this occurs, thinking that its a freeze, i do a restart by using the power button. But today i acted as if there was no white screen and i pressed the buttons as if i was logging in to my user and it worked. This white screen seemed as if it was a cover up.
What could be wrong? Is there anything i can do about it? Any suggestions?
I noticed that i can log in despite the whitish screen i see at boot. I have 2 users, one is a guest and the other is admin. Entering the admin user without seeing is not so easy, but entering the guest can be done with closed eyes since i can enter it simply by pressing enter on the withish screen. Apparently logging in works even if i cant see the screen.
So i enter the guest and then i log out and enter the admin and it all works fine. Isnt that strange? Maybe just maybe might this be something else?
