Frozen screen when waking

Since I updated to 10.10 Yosemite I find it impossible to unlock my Mac after Sleep mode: I can wake the screen ando move the mouse pointer but it never shows me the unlock screen.

I am having the same issue with my Late 2012 27" iMac. Its very frustrating every time I wake my Mac up it just goes to a black screen and cannot get to my desktop. I have tried turning off requiring a passcode, resetting PRAM, fixing permissions in disk utility, and restarting multiple times. This has to be a major bug with Yosemite never before have I had this issue.

  • Retina Mac shows gray screen when waking up: what to do besides loosing work?

    (see also http://apple.stackexchange.com/questions/96188/retina-mac-shows-gray-screen-when -waking-up )
    This is the first time that my Retina MacBook Pro wakes up from sleep with a gray screen. After about 10-20 seconds, the MacBook falls asleep again.
    Some points that might be relevant:
    The only difference between power adapter and no power adapter is that with power adapter it does not go to sleep again.
    The battery is almost full (I closed the lid last night when it was about 90%)
    An external monitor was not attached when sleeping it, so I don't think How to fix a Macbook that does not always draw its internal screen after waking from sleep and having unplugged external display while asleep? applies.
    I've run gfxCardStatus, almost always in "force integrated mode" (to conserve battery). And normally it wakes up correctly.
    I run VMware Fusion 4.
    All software is up-to-date and fully patched.
    I tried to plugin an HDMI monitor and switch displays with Command-Fn-F1 and Command-Fn-F2, but that did not help (it would not switch displays).Before trying to:
    reboot (by force a power off),
    reset SMC
    and/or reset PRAM/NVRAM
    What options do I have that do not loose my work?

  • Blank internal screen when waking with ext monitor connected

    I have a 2011 MacBook pro that is connected to a Dell U2410 24" monitor all the time via a DVI adapter.
    Most of the time this monitor is switched to a different input - the display port which is connected to my PC.
    On the MBP I have display mirrorig enabled.
    Usually, when I wake the MBP, I guess it dettect the external monitor (even when that input isnt selected for display) and leaves its own screen blank - which is really annoying as the only way I have found to get the internal display to come alive is diconnect the extermnal display, or switch inputs on my dell monitor so I can see the MBP display and select Detect Display from the screen utility in the system bar.
    Is there any setting anyone know of to stop this behaviour and make the MBP allways enable the internal display if the lid is open rather than purely relying upon the external connector when waking to decide what to do?
    Just really annoying.
    BTW - for all those people who have been complaining about dead MBPs when you wake them and have an external monitor connected - are you sure this isnt what is happening to you? At first I though my MBP had crashed as well - but in fact it just hadnt switched its internal display back on.

    Problem solved, with some help (here and here).
    Basically, the solution was the installation of a new intel HD 4600 Graphics driver directly from intel.

  • My imac has a gray screen when waking it up from sleep mode. about 9 months ago, I installed OS X Maverick.

    This is the second time this has happened, since installing OS X (9 mos. ago). (I can't recall the fix from the last incident.) Upon waking the pc up from sleep mode, I get a gray screen. Nothing works except using the Command and P & R keys to get to "reinstalling OS X", to no avail. What do I need to do to get it back to normal?

  • Frozen screen when downloading

    Hi
    I was trying to download a theme for my daughters phone and the screen has frozen saying "please wait". Now I can't get off it to cancel or buy another app. I have closed the phone down. I don't want to have to reboot her phone again as she loses stuff on it
    Can anyone help. It's a curve 9320
    Thanks

    Hi and Welcome to the Community!
    Sorry, but you're going to need to clarify..."closed the phone down"??? Exactly what is that, please? Depending on what that is, you may already have forced a reboot.
    But, that concerns me more...you say she loses stuff...a reboot should never cause that, and doing so would indicate to me much greater problems. I do hope she is practicing good backup procedures...for I fear she is headed for disaster and total data loss if not...you can find procedures for that in my auto-sig on this post.
    So, anyway, I actually do recommend a reboot...into Safe Mode:
    KB17877 How to start a BlackBerry smartphone in Safe Mode
    It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see if the theme got installed...if so, remove it. If not, attempt to reboot into normal mode and see how things are.
    Good luck and let us know!

  • 13.3" macbook pro flickering screen when waking from sleep

    I have a Mid 2012 13.3" MacBook Pro (non-Retina) laptop that has been working well, until the last few days.  The laptop has had no physical damage and no liquid damage.  I have put the laptop to sleep by closing the lid.  When the laptop lid is raised and the laptop turns on this last week I have noticed that the screen flickers and then appears to be on, but the screen is a grey color.  I have been able to press the power button to put the computer back to sleep.  Usually when pressing the power button to wake it from sleep the screen issues have cleared up. 
    Is there a known issue that may cause the issue with the flickering/grey screen or could there be a short in the wiring that powers the screen?

    Hey there Oregan Mac User,
    It sounds like you are getting screen flickers when trying to wake your device from sleep. I recommend the troubleshooting form the article named:
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

  • Blue Screen when waking PC up while iPod connected

    Can anybody help here? Often, when I wake my PC from a low-power state I get a BSOD (Blue Screen of Death). The cause is usbaapl.sys.
    Any ideas of what I can do?

    The external HDD may be conflicting with the iPod when the computer comes back out of sleep mode:

  • 2014 Mac Mini shows pink screen when waking

    I have a 2014 3Ghz i7 mac mini which I have attempted to connect two different Asus monitors via two different HDMI cables in multiple configurations. Regardless of the connection combination when the mac awakes from sleep or from the screensaver (to show the login screen) the screen shows up as bright pink and I can barely make out the password box.
    Turning off the monitor and turning it back on corrects the problem as does waiting about 10 seconds for the monitor to go out of sync and return. After this time the issue goes away until the computer sleeps or I enter the sleep saver again and have to re-login.
    Is anyone else encountering this?
    PRAM and SMC have been reset already.

    I don’t know if this solves the pink screen problem, whatever it is. I’m not a techie so this is all I can offer.
    I got my Mini end of December and the pink screen problem just started now. I had no pink screen until I went to change the Sleep / Wake settings. Then I started getting the pink screen with desktop barely showing through. So think when / if you changed your settings from the default. Maybe your problem started after that.
    Returning settings to default doesn't fix it. I also tried to check / uncheck different sleep / wake settings, but didn't work either.
    I have the latest Mac Mini 3 GHz
    Intel Core i7, 16 GB RAM Yosemite 10.10.2.
    External ASUS PA248 monitor via HDMI.
    I know everyone has different set-ups with slight variations in the problem, but maybe this will help some people. It seem to have worked to solve the pink from appearing, but I don’t think it has solved he actual problem. At least if I have to go to my computer every half hour, I don’t have to wear out my monitor button by having to turn it on all the time just to get rid of the pink screen.
    I know people want their Mini to sleep but for these instructions your Mini will have to remain awake all the time.
    This is my monitor set up.
    Screen saver set to go on in 10 minutes.
    Monitor shuts off in 15 minutes.
    The Mini stays on all the time, no sleep or wake cycles.
    1. Go to ENERGY SAVINGS
    2. The only thing I have checked is, “Prevent the computer from sleeping automatically when the display is off. Leave the rest unchecked".
    3.  Then go to SCHEDULE Uncheck these,
    START UP OR WAKE and SLEEP settings.
    Hit OK
    Exit ENERGY SAVINGS.
    Let your monitor turn off, come back later. Sit down and re-try to to turn on your desktop. DON'T click away on your mouse or move it back and forth furiously like you want your desktop to load RIGHT NOW. Well I did that and the system didn't like that and the pink was back. It seems the system needs a few seconds to load up the desktop. Click the mouse button once, or move the mouse a a TINY bit. Wait a bit and the desktop should appear WITH NO PINK SCREEN, hopefully.
    Hope this helps.

  • Frozen Screen When Creating a Shared Review

    I am trying to create a shared review through a network folder, however, it freezes with the following message box: "Status: Creating shared folder location...". This is the first time this has happened, as I have been able to create a shared review many times before using the same network folder. Can anybody help me with this issue? Thanks in advance.

    I am trying to create a shared review from an Adobe 9 pdf, however, it freezes with the following message box: "Status: Creating shared folder on acrobat.com". This is the first time I have tried using Acrobat.com to share and collaborate on documents.  When I click "next" from the initial Shared Review screen my understanding is that I should be prompted for my username and password for Acrobat.com but I do not get that prompt.  "Authenticating Adobe ID..." and "Communicating with Acrobat.com..." messages flash on the scren and then the Shared Review dailog screen that asks for "Delivery Method, To: CC:, etc." comes up. I fill in the fields and then it attempts to connect but never makes the connection and returns the above message and I hit the retry button but it never completes.  Can anybody help me with this issue? Thanks in advance.

  • 13" macbook pro retina 2013 problem: blank screen when waking up from standby

    I bought a 13" macbook pro retina 2013 about 3 months ago and it is for about a week or two that I encountered a problem: when I close the lid and open it after a while(or it goes to standby by not using it for some time and then I wake it up by pressing a button), sometimes it shows a blank dark screen(with mouse cursor) for about 15 seconds and then either the screen is turned off(and by pressing a key it shows the login screen) or it shows the normal login screen.

    I also have this problem, and now the
    NVIDIA GeForce GT 650M is not working at all
    I use gfxCardStatus for work on integrated card and i can't use other displays obviously, because all video outputs (HDMI & Thunderbolt) are taking their ways from discrete card (but working on other displays is my profession of audiovisual artist). My world guarranty is over now, new motherboard costs near 1500 $ and now i don't want what to do.Maybe reballing of videochip will help me, but i'm afraid that not autorised service in my country will kill my motherboard at all. This is my first mac & i have lost many time for take the money for buyng it. I have so much frustration.

  • Frozen screen when iPod unplugged

    I have a generation 2 iPod and it will say it's charged on the computer and then as soon as you unplug it from the computer (properly ejected) the screen will freeze with half the screen showing. Then you can't do anything. I plugged it back into the computer and the do not disconnect sign goes on and you can't press anything. I tried resetting it an nothing happens. the last time I unplugged it trying to make it work, the screen froze and then slowly faded away. I plugged it back into the computer and the 'do not disconnect' comes back on. Very frustrating. This is brand new.

    I tried resetting it several times. It says it's charged and works fine when plugged into the computer, but as soon as I remove the usb cable then the screen kind of goes half black and freezes. I tried resetting it from this point, but the screen just slowly fades away and the only way to get anything back on it is to plug it back into the computer.

  • Black screen when waking macbook pro retina from sleep. Mavericks

    Hi, ever since I updated to Mavericks i've been having this problem when my early 2012 rmbp wakes up from sleep and the screen is black except the time and battery info. When i start moving my mouse around the screen it's still black UNTIL I click and drag on the desktop wallpaper and whatever selection I clicked, my wallpaper will show. In order to actually use the laptop I either have to restart my computer or click and drag all around the computer screen so everything (wallpaper, app icons on dock, apple logo) will show up. Really strange. Not a big problem, but it is really annoying sometimes. Anyone have any suggestions?
    Thanks, Ryan

    well, the sad news is that although there are thousands of people with this issue, Apple is NOT going to recall the computers and fix them. This is particularly bad news for me as I am part of a team that is working with the poor in a devastated area of the Philippines and I cannot afford to get a replacment.
    I don't know what I am going to do when my Macbook will not wake up anymore....
    If anyone has news or suggestions on how to get help from Apple, please forward it to me

  • Mysterious white screen when waking up the phone by using the lock button

    Anyone else experiencing this?
    Every now and then (about 5 out of 10 times) when my phone would fall asleep in an unlocked state, and i press the top lock button to wake it up, my screen turns white for a few seconds before returning to its normal screen. This doesn't happen if i wake up the phone with any other key (including the silent button on the top). I am only having this issue with the lock button. Is this something that is normal on all 8900s? Or can this "issue" escalate to something more serious? Any input would be great. Oh by the way, i already tried multiple battery pulls (did not help).

    I am unable to get into the chat.  I tried explorer and chrome and neither will allow us to access the chat.  It continues to go around and around.

  • Beach ball on black screen when waking Mini from sleep

    I am looking for a way to fix this frequent problem. About 25% of the time I wake this 2-year-old Mac Mini from sleep, it will show a spinning beach ball or a regular pointer on a totally black screen. The monitor connected is an Acer, by the way, and it's had multiple color calibrations done to it... Anyways, the pointer or beach ball doesn't go away if you just let it sit awhile, but it does move with mouse motion. So the only ways of getting to the login screen from there are:
    hold down the power button on the computer for 10 seconds, then start it up as usual.
    unplug the HDMI cord that connects to the display from the back of the computer.
    What does not work:
    unplug the HDMI from the back of the display
    turn the monitor off and on
    unplug and replug the monitor
    pressing keyboard shortcuts to shutdown, reboot, sleep, etc. don't work.
    So from this I've deduced that it has something to do with the Mac Mini recognizing the Acer display and having to refresh that port's connection.
    What I've already tried that has not permanently fixed the problem:
    Reset the PRAM
    Having frequent power outages counts as resetting the SMC, right?
    restarting the computer (duh)
    Doing the Apple Diagnostic test
    Had Disk Utility test the hard drive (well ok its an ssd) and found no problems with it.
    Help! It's not so much a problem for me but one other person who uses this computer is computer illiterate and cannot do a hard reset or figure out which cable goes where. And please, please, please do not take the easy way out and tell me to reinstall OSX (it's mavericks by the way). Thank you very much.

    Humm... May have something to do with the straight HDMI connection, others have also complained about similar problems using a straight HDMI connection.
    1. You tried a different HDMI cable...? (you didn't say)
    2. What model is your Acer and what other inputs (DVI, VGA, etc.) does it support...?
    I run dual DVI Samsung monitors on my Mac Mini and have not experience any problems. One is on the Apple Supplied HDMI to DVI adapter and the other in on a Kanex Mini DisplayPort to DVI adapter.
    No a power outage does not equal an SMC reset. If fact, it can have just the opposite effect and throw the System Management Controller off kilter.

  • IMac has empty blue screen on waking from sleep

    My iMac goes to a blue empty screen when waking from sleep. No login. No desktop shows up. Any ideas or explanations? I am working on clearing off hard drive space - currently about 100GB available on 1TB system. But I do not know if that could be a cause.
    Thanks for any help you can give.

    As far as resetting the SMT, my only option was to hold the power button down and force the system off anyway, since I couldn't see anything.
    I did reset the PRAM, which ended up being disastrous! Instead of encountering the problem each time the system went to sleep like what had been happening, after I reset the PRAM, it started doing it immediately during startup. I couldn't even get to the desktop. The computer was completely unusable!
    If I hadn't had a spare monitor around, I wouldn't have been able to do anything with my computer! Interestingly, the problem doesn't occur with my old Apple Studio Display, just my new Apple Cinema Display.
    You better revert to 10.5.4 and stay with it until this is resolved.
