Graphic problem of mission control

Hi, I have an early 2013 MacBook Pro retina runs El Capitan 10.11.6

Launch of Mission Control, there is a graphic problem: miniature Office are all gray, as you can see in the screenshot.

I already tried to quit smoking Dock in activity monitor and running "killall Dock" in the Terminal. Restart the system, the problem persists.

Any ideas?

Hello GalaxyWorker,

Thank you for using communities of Apple Support. It is my understanding that when you use the Mission control the thumbnails are gray. I often use in Mission control, so I know not being able to see the thumbnail of the available screens can be useful. I'm happy to help you to get this resolved with you.

You did a great job trying to fix this problem yourself. First, I recommend that you test the problem in safe mode. Boot in safe mode allows your Mac perform certain controls, delete the cache and prevent the opening and start-up items to open automatically. Follow the steps below to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

To leave safe mode, restart your computer without pressing any key during startup

Try safe mode if your Mac does not end commissioning

If the problem does not occur in safe mode, but returns when you restart normally, try to disable the login items using the link below.
OS X El Capitan: If you think you have incompatible connection points

If the problem occurred then in safe mode, it is possible the user settings or files are the cause. In this case, please try the issue in a new user by following the instructions in the following link.

Have a fantastic day!

  • BONES of Sierra crashing to the LOGIN screen while using the service of mission control.

    After Sierra OS upgrade my MacBook Pro hangs on login screen every time I have used the function of mission control.

    Hey hernj103,

    Thank you for using communities of Apple Support. I can see your post after upgrading to Mac OS Sierra that reboots your MacBook Pro, if you use mission control. There could be a number of reasons that could cause this and I want to help you have a reliable working Mac, so I'm here to help! If you have not already done, you want to make sure that you have a backup of your data and you can use the option in the link below:

    Use Time Machine to back up or restore your Mac

    Once your data is secure, you'll want to test this function in Mode safe mode and see if you get the same effect. Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening. Also, it verifies your startup disk and trying to fix problems if necessary directory and delete font caches, hiding the kernel and other files of the system cache. The following link can show you how to start your MacBook Pro in Mode safe.

    Try safe mode if your Mac does not end commissioning

    If you continue to have problems after the safe boot mode, let know us and we can continue to solve the problems there.

  • Mission control: cannot close the empty offices

    Hi all

    I've seen a few posts related to this but not definitive answers. My mid-2011 iMac (OS 10.11.6) gave birth to two "" extra spaces or empty desktop computers in the control of the Mission, and I am not in a position to close, even now the key Option. One is named "Calendar" (I normally put on his own desk, but it is an extra that will not disappear after leaving this request) and the other simply "office."

    This happened earlier, and I think that I fixed it just by restarting, but that did not work this time. That said, I must point out that the last two restarts (when the problem started) have been to Boot Camp in Mac OS. I don't know if it's relevant.

    Thank you!

    FWIW, when you launch the Mission Control, a simple "office" is listed at the top by default. It is not something, you can close.

  • Qosmio X 870 - 13v - graphic problem steam L4D game - black shadow on the light

    Hello

    I play this game using 2 PC Toshiba laptop.

    A Satellite L670-1KZ: 2.67 Ghz - Radeon Mobility HD5650 - RAM 6 GB i5.
    A Qosmio X 870 - 13v: i7-3630QM 2.4 Ghz - GeForce GTX 670 M & Intel HD Graphics 4000 - 32 GB of RAM.

    On the 1st, I have no graphic problem.
    On the Qosmio, I have a BIG problem with little light that have large black stain on it.

    You can see the 'bug' on YT here below:

    https://www.YouTube.com/watch?v=c4E2DFScyfU&feature=youtu.be

    The configuration of the game is the same on both machines with the exception of the resolution.
    My drivers are up to date (GeForce & Intel).
    I uninstalled the game twice only = no results.
    Settings, to control panel Nvidia, I changed several times (Note option shadows cache) no = no results.
    I played with game config below only = no results.

    I posted on the forum of steam only = no response.
    I posted on the forum of Nvidia only = no response.

    So, can you help me solve this problem?

    With our thanks,
    Guillaume.

    You have any other graphic matter using this Qosmio X 870 - 13v?
    I mean other problems related to the image to appear in other games and other applications running?

    Otherwise I n t think that there is something wrong with the laptop.
    In this case, it looks like very specific issues between this game and probably the graphics driver.

    It turns out that you won't encounter problems under this game the Satellite L670 with ATI driver.
    The Qosmio is supported by the nVidia GPU

    I think there must be a link any between the nVidia GPU and this game.
    In my opinion you should look for the solution in the steam forums or nvidia even if you have not received answer yet.

  • Cannot assign Launchpad and Mission Control to their default function keys

    Given that I've updated my Mac Mini to 10.11.3 pressing F4 doesn't have to rely on the Launchpad. The same with Mission Control and F3. I tried to use Launchpad to this key in system preferences, but would not take the selection of key. Does anyone know a solution to this problem? I use an Apple Wireless (Bluetooth) keyboard.

    What happens when you press these keys?  What about other f keys? Is this always the case when you connect as a different user, for example, comments?  You continue to experience this behavior when you start in Safe Mode?  Have you tried to reset NVRAM and PRAM?

  • 10.11.3 mission Control "Show Desktop" does not work with 3rd party keyboard

    I use a KENIMBENI Multi sync Bluetooth keyboard as seems to be the best solution when you want a wireless keyboard with a numeric keypad on a Mac.

    The KENIMBENI keyboard has its own combination of keys rather than Apple-command 'Mission Control' 'Show desktop '. It was working fine until 10.11.2. But now, after upgrading to 10.11.3, I find no way to make this button (or any other combination of the command 'Show desktop') works. Some key or combination of keys I enter the keyboard and/or the Mission Control preferences pane, will be shown on the screen, but the system does not react to it. I also tried switching to use several spaces to use a single space extending on my two monitors, assuming that it could have to do with behavior change - but none of this helps.

    I have an another Mac Apple original wired keyboard, and here the command-'Mission Control' combo works fine as expected.

    Can any that confirm - and perhaps know no work around? I'm a little old school management Finder and file and so use orders 'Show desktop' several times a day. Thanks in advance for your suggestions!

    You should discuss with the developer of the material. If it works for your OS with material Mac the fault lies with the proponent to provide a usable instance of this device with a newer OS, if they wish. In addition, we use a Logitech wireless keyboard solution full size and they are solar powered so no battery and no problems so far.

  • Pavillion dv7 4177nr: VGA output problem and catalyst control start link

    I don't know if the problems are related or if I made things worse.  It started with an error message on uo start saying that there is a problem with Catalyst Control fail to start.  He always allowed did not work me to function normally until, in front of an audience, the o/p to a projector VGA connection.  I had a spare cable who has not remedied the situation then my class sitting around the laptop.

    Another symptom is that the HDMI output is not working.  I do not ko wif it's a separate issue.

    With the notion that it was connected, I set attemping to remove and re-install the drivers AMD and blindly assumed that it was where I'd get the update of the Cat command.

    I used the AMD compatibility checker and installed for the AMD M880G with ATI Mobility Radeon HD 4250 graphics card.  The driver version is 8.770.2.1000 dated dated 19/09/2010

    I can't duplicate the display or projector only use but when I attach an external monitor laptop change resolution as to accommodate the additional display.

    I only need to check the applicability of the changes that I made, or I need help to plan a way out of the mess I made.

    Hello g_david,

    Thanks for the quick response!

    To eliminate the possibility of a software problem, I have recommended to perform a backup and restore of your operating system. This can be done by following this document on the backup of files (Windows 7), and more to perform a recovery of the system HP (Windows 7). This should return your system to the factory settings.

    If the problem persists, please call our technical support at the 800-474-6836. If you do not live in the United States / Canada region, please click the link below to get help from your region number.

  • Windows 7 Graphics problem: graphics would become all deformed and weird looking

    original title: graphic problem Windows 7

    Hi, I recently got a new laptop with Windows 7 pre-installed on it.  Sorry if this problem has already been asked before, but I couldn't find someone else with the same problem I have.

    Sometimes, the graphics would become all deformed and weird looking.  Look at the screenshot I took:

    And it occurs for each program, not only on the desktop.  I could usually get rid of the lines by reducing the window and maximizing it again.  But it's so boring.

    My graphics card is a Mobile Intel (r) 4 Series Express Chipset Family.  I updated the driver from last night, but the same thing happens again.  So I don't know what else could be the problem.

    Thanks in advance!

    Check if your video card has its own program/parameters adjustment control panel and use it to adjust your settings more towards the side of the 'quality' rather than the side 'Performance' and see if that smooth your edges for you.  Also, you said that your system is new.  You can look into having served through your warranty.  You also need to make sure that it is not getting too hot.  Laptops produce a lot of heat and if it doesn't get good ventalation / or enough, then he can begin to display this type of behavior.  I had to go out and get a 'cooling block' for mine to keep it cool.  I hadn't started to have problems because of the heat, but I decided on my own that he was too hot.   Hope this bit of info helps.

    From your problem description, I understand that AMD does not work.

    As you are referring to the "Switchable Graphics" in Amd catalyst control center and Amd is these software development so I suggest you to get in touch with Amd and check.

    There will be a new version of JMC included in the JDK 8. This version will support Kepler. You will be able to connect to the 7u40 times + and 8 Java virtual machines using this version of JMC.

    I hope that the Eclipse performance problems will be fixed from here there, but I don't know who.

  • Allocation of spaces for CS6 apps in Mountain Lion Mission Control

    It seems that you can assign is more specific spaces for CS6 applications in OS X Lion mountain. "" This feature is possible by right-clicking (or Ctrl-clicking on) an application in the dock icon and selecting Options "assign to" office (or office #). The app will continue open and operate within Mission control currently selected up to this that changed. This option is currently not available for the CS6 applications, it seems, but I'm sure that the feature was possible with applications of OS X Lion and CS5...?

    1. Wanted to make sure that the Adobe team was aware of this problem.
    2. Hoping the team Adobe will present an update to resolve this issue.
    3. I was wondering if there is a solution or if there is just something missing me.

    PS: You can still assign CS6 apps a specific space by dragging in Mission Control, but they don't re-open and will continue to work in this space.

    FYI: The possibility to assign a space is now available in the context menu for Photoshop and the app will resume in the assigned space. This option is not yet available for other applications CS6.

  • Graphics problems in macOS Sierra on Macbook Pro

    I have a 13 "mid-2016 Macbook Pro (model MacbookPro 7.1 - 2.66 GHz/8 GB RAM) I've recently upgraded to Sierra. However, I noticed a slight increase in glitches since the upgrade - serious glitches. For example, the animation for arise Applications appears as two images, the majority of applications (including integrated) sparkle and on top of that, applications like Microsoft Remote Desktop and Parallels Pro 12 do not work right due to graphic problems (MS RD comes constantly creates an empty black window while in the analogies I was forced to power off the virtual machine dirty because all the options of the application itself that uses OS x) interface were flickering at which makes them unselectable).

    In fact, the graphics flickering and stuttering throughout what using Mac OS are quite widespread. Open a new window in Chrome, same thing. Same thing with Safari. Or iTunes.
