IMac (Intel) :: Black Screen On Wake - OS X 10.9.3
Jun 1, 2014
This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.

iMac (27-inch Mid 2011), OS X Mavericks (10.9.3)

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all.

When I need to go somewhere or just eat lunch, I put my iMac to sleep. After that, when I come back to wake it back up, it stays black.

Just got a new Mac pro and installed an SSD as the boot drive. I was downloading some apple software updates and left the machine alone to download for an hour.Came back and it was asleep or hibernating (is there a difference?)At that point I clicked the mouse and I could hear it start back up but NOTHING came on the screen, just black.I could press a key on the keyboard and hear the error type noise so the desktop was active, just not being displayed.
I disconnected my mini display port (I have a 24' Apple cinema LED display) and plugged it into the second mini display port on the back and it came back on.Anyone know what this could be?A result of an SSD boot drive or do I need my LED display plugging into a particular mini display port out of the 2 on the graphics card?

I have a MacPro 1,1 (2006) 2.66GHz that it is always working as a home server.
After some time working idle the screen goes black. When I want to wake up there is no response. The screen turns into safe energy mode blinking his LED light power indication. I have to force shutting down pushing phisically the power button for some seconds.
Graphic Card problem? I have another one but I don't test it for now.
I have made a PRAM reset and SMC reset shutting down the MacPro, unplug the power and push the power button for 10 seconds. No results at all.
Even putting Energy System Preference on NEVER (computer sleep and screen) after some time (2-3hours) the MacPro goes to black screen.

When I wake from a long sleep, my screen comes on but everything is black. If I move my mouse around, the tiles behind the pointer switch over to whatever app is open. When I invoke expose/spaces, the screen fixes itself and displays everything.

In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours.
Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in). This did not occur until I got 10.7.3 and only within the last 2 months.

I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen. It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual.
This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpad
Why automatic display sleep is causing this temporary black screen? I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen. I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.

Middle of last month I bought a 20" IMac. Everything was fine up until about 1 week ago when the screen went black. I clicked on the mouse button several times only to have a password box pop-up. After filling in the response, all was fine.
Next, same scenario but the password box didn't appear any more. The only way to get the screen back was by a forced restart.
I turned off the screen saver, set the 2 controls in energy server to off, unchecked the box at the bottom left & put "auto login" to to on the Accounts window.
Problem continued.
Next move was to zap the pram, this was 2 days ago. The screen didn't go black but often asked for my pw. It's now back to its beginning phase which is a forced restart !!
I was told that it was due to Leopard 10.5.2 & am considering going back to 10.5.1

My beloved imac desktop just started this after a brief power outage (it didn't affect my husband's imac) or any other machines in the household. I've tried booting while holding the 'option' key but it still goes to "no bootable device" ...

What is happening to my computer. This is the 2nd time it does this: all of a sudden the screen becomes black with reverse fluo colors.
I have to force quite with the push button & restart it. I repaired the permissions & restarted it. It's working again, but I am wondering if I have an alien in it.

I have a 27 inch desktop. Upon turning the computer on within seconds the fan comes on. Then it goes to a high fan. Then it goes to a black screen. Then it shuts off. Then if you click the mouse it will come back on. This cycle repeats itself every 5 seconds. Only one time in the past month did it turn on normally and run for me.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

After my 27" i7 wakes up from a long sleep (roughly over 1.5 hours), something very odd goes on with my color profile and/or screen. Approx. 5 second or so after waking, the screen color appears to wash out quite a bit. You certainly have to be quick to notice it, but something is definitely going on.

My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

Ever since I bought and downloaded OS Lion, whenever I put my mac to sleep or it goes to sleep on its own it occasionally won't wake up from sleep. It has to be manually rebooted. Is anyone familiar with this problem. Apple must know about it by now. I'm not lugging my 27" iMac into the apple store to have them look at it unless it won't reboot. Hoping it doesn't come to that...anyone familiar with this or have ideas on how to fix it? I don't know if it's a 3rd party software issue or just the OS.

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.
