Have a new BTO 27" iMac I received a couple of weeks ago. Of course it is running Lion 10.7....
I am having a screen problem "waking" my iMac. (I also have this problem randomly on my MB Air - mid 2011 model)
After the iMac is in true sleep mode
(I have it set to enter a password after sleep mode)
Screen is blank/off
I "wiggle" my mouse or trackpad
Screen is still blank (sometimes it may display my screen saver, but the screensaver is frozen)
If I start moving the mouse or trackpad, it starts "un painting" the black screen. You can see whatever is supposed to be on the screen, such as the logon "button".
It is really wierd. Like a black "overlay" is painted on the resume from sleep screen. As I move my mouse or trackpad, it is basically erasing the black, to show what is underneath. Each movement of the mouse, erases a small black square.
I usually move my mouse around the middle of the screen to uncover the logon button. Press the logon button. The screen magically reappears as normal. I enter my password and system logs back on normally.
It only seems to be when the iMac is in really deep sleep mode. If the screen is just blank for an hour or so. I move the mouse/trackpad, and the logon screen is immediately displayed normally.
Any thoughts or recommendations?
Thanks to all in advance.
