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.
View 4 RepliesFor 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.

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.
View 1 Replies View RelatedI'm on Mac Pro os x 10.5.4 and having a problem with my computer waking up from sleep or as it is booting up.
As it wakes up from sleep, the screen becomes blank or shows weird, pixelated bars all over the screen. When I try to move the mouse or press something on keypad, the computer freezes after and I would have to force shutting it down by pressing the power. It doesn't always happen, but quite often these days.
Also, when it's booting up, it sometimes will freeze with a blank screen in the middle and won't show the desktop.
Everything worked fine until a few days ago, and i'm wondering what's suddenly causing this problem.
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?

Having some trouble with my iMac (the version right before the intel iMacs came out. further info can be provided if needed). Running all the latest software updates etc. When I put the iMac to sleep, it goes off as normal. With the usual white light. However, when coming to wake the iMac it won't respond to the keyboard or mouse. I have to shut it down at the power button, and then turn it back on.

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.

Does anyone know if it's possible yet to wake an iMac from sleep via the internet? I'd like to use remote login via SSH to an iMac from an ibook, but it is quite useless unless I can wake the iMac from the internet.

View 9 Replies View RelatedI have an older iMac (MA589LL) that I recently upgraded to 4GB and Snow Leopard which is running beautifully. I do have an issue with it though, and it's been occurring for a while: Whenever the machine goes to sleep and I wake it up, the monitor turns on just fine but after about 5 seconds it goes back to sleep. I have to repeat this about 3 times and then it is fine. It's an annoying issue but not a deal breaker as I can just turn it off. I searched for sleep issues/turn off issues and have not found anything.
NOTE: Issue occurred before the upgrades. I've also tried resetting the PRAM and NVRAM. I have also used different keyboards/mouses.
I bought a new unibody Macbook around 4-5 months ago and I've generally been very impressed with it. It's my first Mac and considering all the problems I'd had before with Windows PC's, it's quite a relief.Anyway, here's the issue. When hooked up to my 24 inch Dell monitor there are numerous problems. Originally it just started with the screen intermittently turning itself off and on, and there being a sleep/wake issue. I did some research then and discovered that this was by no means a problem confined to me. Knowing this I was prepared to wait until Apple fixed it with a firmware update or something, as the problem was annoying but not devastating.
However since then the problem has got significantly worse. Not only are the screen flickering, sleep wake/issues occuring much more frequently, but there are other problems. For instance, the menu bar and the dock sometimes fail to show, and I've been having a very weird problem with the Logitech mouse I use. Even though I can move the cursor generally I can't click, and when I can, only the right mouse button works.The same is true with the trackpad, so it's not a problem with the mouse.
When these problems occur the system generally seems to be very slow. I've checked the 'activity monitor' and the use of 'system memory' seems to be very high. For instance, at the moment (I'm using my Macbook by itself) I'm running a few applications (Mail, iCal etc.) and I've got 1.09 gb of free memory. Last night I was running exactly the same applications and I must have had less than 0.4 gb of free memory. The pageout numbers were fairly high as well.
It's strange because when disconnected from the external monitor the Macbook seems to work seamlessly. I just don't understand how some of the problems I've experienced (such as the mouse issue) can arise from problems relating to the external monitor setup. What do you think? Should I be worried that these issues are perhaps indicative of a greater problem? Either way, the problems are becoming hard to deal with. Very disappointing.
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.

For the past few months i've been having issues with my imac 2.66Ghz 24 inch. I'd say almost half the time when i put my imac to sleep it doesnt wake up no matter how many keys i press and it just stays stuck on a black screen. I know that when you put the computer to sleep you hear absolutely no noise however in this case i hear a slight fan noise despite it 'sleeping'. When this happens i always have to use the on/off button to do a reset. What seems to be the issue here??
View 1 Replies View RelatedEvery now and then, my 2010 27" iMac won't wake up from sleep by pressing a button on the keyboard or the Magic Trackpad. The computer won't even respond to a tap of the power button so I end up having to hold it down for a hard reset.
It seems like this only happens when the Mac sleeps with an application running (usually EyeTV 3). Is it an issue where the bluetooth keyboard and trackpad aren't communicating with the Mac properly?
I had my iMac 27" for two months, and I am very pleased with the machine - except for one thing. When I put it to sleep, the computer just go to sleep in a couple of hours and then return to no-sleep. It started just after I bought the computer. I always set my computer to sleep, and so I did even then - but the first thing I noticed was that the hard drive was started during the first night. Strangely, I thought and put it to sleep again. Then I fell asleep, but when I woke up next morning the computer was on.
Then I wrote on another forum and they told me to check out: Wake up in network access, which I did. And then it got better. Now the computer has been without problems for a month, but then a few days ago it came back. This box is still check, so it can not have anything to do with it this time. I've also tried turning off all programs, the keyboard and mouse when it has gone down to sleep, but it still restarted. What is wrong? Please run with Sleep and it is a program that will prevent the computer to wake from sleep, but not:

What can I do? Can I submit it to Applecare? Some peoples say you do not have to turn off a Mac, but I want to put it to sleep, but it starts up the next day. I've also restarted the SMC, but it gave no effect.
This problem started after a power surge a few weeks ago. The surge protector fried, but seemed to save the computer in the process. Symptoms are:If the Mac goes to sleep, the fans eventually go in hyperspeed mode and it's impossible to wake.Boot time is over 6 minutes. 1.5 minutes on the gray Apple, then 5 minutes on blue screen.In verbose mode, I get some IOKitWaitQuiet error just before the blue screenI repaired permissions, checked the disk with Disk Utility, and zapped the PRAM. Here's the console report of a restart. The blue screen was between 8 and 8:05.

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.

I've been experiencing this issue off and on for about the past 10 months. I just upgraded to Snow Leopard tonight and the first time my Unibody MBP's screen saver came on and I got it back to the desktop the entire tint of the screen is intensely cooler. I have to go to Preferences>Display>Color and it automatically goes back to normal. The original "Color LCD" is highlighted, so it's not as if an entirely different profile got selected. If I click on Adobe RGB (1998) I get the exact same cool tint that I get when I unlock after the screen saver appears. Once again, it doesn't happen every time, but it does happen enough to sort of worry me.

View 2 Replies View RelatedI'm experiencing very annoying sleep/wakeup problems with Mid 2007 iMac. I think it started after 10.5.6 update.
1. iMac does not go to sleep according to the Energy saving settings, this was actually from the day one. It goes to screen saver, display sleep, but not complete sleep.
2. Since automatic sleeping does not work, I put it to sleep manually by pressing Power button. but in this case it sleeps so deep, that it does not wakeup. The only way to bring it back is to hold the Power button to complete OFF and then power back UP.
I tried, PRAM and permissions tricks, nothing seem to help.
i just bought the imac 21.5 inch with ati radeon 4670 and the base spec. after few hours of playing with this new toy. i realise that when you press the shutdown button, it will put the imac to sleep instead of showing the shutdown/restart option that i have on my macbook. Is there any way to make it work like a macbook power button. secondly, whenever my imac wake up after sleeping, the fan will run faster and automatically went to sleep again. this issue just keep repeating itself. i have no choice but to shutdown the imac and boot up again. Thirdly, i try the machine on WoW and i realise that the sound is rather choppy
View 2 Replies View RelatedI'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.
Imac completely dead and not able to wake up after putting to sleep.This is a new error on top of many others.Very annoying one has to reset and restart to overcome something that is supposed to work o.k?
View 2 Replies View RelatedWhen 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.
View 3 Replies View RelatedThis 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.

I opened up system prefs to calibrate my screen for the first time so you will need to go to 'Displays' then 'Color' then 'Calibrate' on the side.
It will open up a few tests and when finished make a new display profile, when your done constantly switch between your original profile and the calibrated one (imac calibrated).
You will see a huge difference in enhancement of the screen color lighting and adds more texture, you should look at your wallpaper when switching I chose the snowy mountain wallpaper from snow leopard and it really improved a lot.
