Entire dock bounces, Mission Control laggy opening

When I hover over dock, the dock bounces back open twice. Also, Mission Control and Safari are very laggy. This happened about a month ago and eventually went away. It came back after downloading the new update.

Problem Solved.... opened up Autocad and quit it and the problem goes away!

  • Blinking gray desktop background and no dock/launchpad/mission control

    I just updated to Mountain Lion and my desktop background keeps changing from the picture to a gray screen. My dock also wont appear on the bottom of my screen and launch pad and mission control also do not work. I called Apple once and I reinstalled ML once already and its still doing it. Any suggestions?

    reboot, hold CMD+R .
    you'll be in the recovery partition.
    go to disk utility, and Verify and Repair your boot disk and its permissions.
    exit out of Disk Utility and then go to the area that says reinstall Mountain Lion.
    Do so.
    This will hopefully fix your issues.

  • Is it possible to show the dock bar only in mission control mode?

    Hi.
    I dont wont to have the dock in my workspace. Can I move the dock to mission control an launch apps from there?

    You could however maybe trick the Dock by setting the delay rate to some high number, say  one hour.
    In terminal copy and paste:
    defaults write com.apple.Dock autohide-delay -float 3600.00 && killall Dock
    To restore the default behavior, enter:
    defaults delete com.apple.Dock autohide-delay && killall Dock

  • MISSION CONTROL, LAUNCHPAD, and FULL SCREEN APPS (one month later)

    I'm pretty good embracing a new thing when it comes along.  I downloaded LION the day it come out, which was over a month ago at this point. On that day, I immediately found MISSION CONTROL and LAUNCHPAD both uninituitve and pointless.  Unhandy iCandy.   And of FULL SCREEN APPS?  Not necessary on an iMac anyway.
    So I quickly sought out quick solutions to 'fix' these new features.  Launchpad and full screen apps have the advantage that they can be simply ignored.  This is a good thing.  Mission Control, on the other hand, got in the way of a beloved feature for me:  what was once SPACES and EXPOSE.  That is, I couldn't simply ignore MC because I still needed the previous helpful features in Snow Leopard.
    My solution was kind of surprising and eye-opening.  It's complicated to explain but I thought I'd share.  This conclusion is likely best suited for someone not using a small screened Mac.  It turns out that most users (with big enough screens) don't really need Mission Control, Launchpad, Spaces, or Full Screen apps. 
    At all.
    Let's go through that conclusion, one by one:
    FULL SCREEN APPS
    If you have a relatively big screen (20 iMac for instance), why do you need Safari full screen?  Unless you intend to sit across the room from the computer, no reason.  And there's lots of bright empty space when you do this.  Do you need the Mail app full screen?  If you need reading glasses, maybe, but otherwise, nope.  I find it's easier just to stretch out an app pretty big and leave it at that.
    Full screen apps DO offer a nice feature which is making your desktop, menubar, and dock go BYE BYE.  I can see where sometimes this is a useful feature, but typically -- NOPE.  Typically I want access to my dock (to switch between open apps without the added step of cancelling full screen first), and typically I want access to my menubar so that I can glance up and see what time it is or find an app menu quickly.
    The only feature I find worthy of praise with full screen apps is that they hide the clutter on your desktop.  But there's an app in the Mac App Store which makes your desktop icons vanish with the touch of a button (CAMOUFLAGE).  I mean, what's the point of a wallpaper if you bury it with desktop clutter or eliminate it with full screen apps?  If it's a busy and distracting wallpaper, umm... you picked bad wallpaper.
    LAUNCH PAD
    LAUNCH PAD offers an iOS experience inside OS X.  At first I thought it was completely silly.  After a month now, I kinda get why it's there.  Kinda.
    You see, before LP, to duplicate it's functionality, you'd have to organize folders yourself.  Put folders of various apps together.  Place them somewhere in the finder heirarchy.  Then drag those folders into the part of the dock with the trashcan.  Then you could click them open and have access to similarly themed folders of apps.  The problem here, of course, is that unless you're a power user, you'll never do this.
    So Apple thought, AH-HA, we'll just drag into OS X a paradigm that users already get from iOS.  Clumping apps together any way you like them.  The misfire, if you ask me, is not allowing users to drag the new iOS folders straight into the dock when finished.  That is to say:  copies of said organized folders.  It's as if Apple's software people have complete contempt for the dock -- and are desperate to have users abandon it.
    My problem is that I like having folders in my dock of stuff I need.  It just works, as Steve says.  Going to the same EXACT place every time I need anything is more intuitive and graceful than ADDING an app called Launchpad that launches you into a different finder altogether.  Makes zero sense and THIS is why I say, like FULL SCREEN APPS, LP can basically be abandoned.
    By the way:  need proof that Apple has complete contempt for the Dock?
    MISSION CONTROL/SPACES
    A month has passed since MC was introduced and SPACES was eliminated.  I dare anyone to tell me why either is needed at all.  Before you get iMiffed, humor me for a moment and hear me out.
    The notion of SPACES was that it's a neat way to keep like minded open apps together.  I totally bought into this, back in the day.  So much so that I was iMiffed when it was gone in Lion.  But let's look at this closer.
    The REASON why we needed SPACES was that we could have WAY too many windows open at once on a Mac.  Right?  A big mess of windows covering each other up.  Suppose you're surfing in Safari but need iTunes?  But iTunes is hidden.  So what did you do?  You went to Spaces as step one, moused over to your iTunes space as move two, and then clicked it as move three.  Seems like a great solution until the day you discover that you could simply click on iTunes in the dock as move one and arrive at iTunes.  As one step.  Period.  Really simple, right? 
    Why have Spaces and apps dance around when you can just click the app you want and be done with it?  That's the critical observation to make in order to follow my entire line of reasoning.  Sure, it may look really cool and make Windows machines look like junk, but at the end of the day, why add two steps to something you might do 100 times a day -- switching between apps.
    So why OH why did Apple add Spaces?  Simple:  because too many apps were visible at once in one 'desktop' window.  So if you can build many new desktops, there might only be one or two in each.  Great solution.  Right?
    Wrong, as it turns out.  Because we still have the two extra steps.  It's a weak solution.  And it's in complete contempt of the Dock, which as it turns out, offers the strongest solution.
    The strong solution would be that only one app is visible in your Mac's window at all times.  Say you're in Safari.  Despite having 12 other apps open, you only see Safari.  Your dock tells you that you have other apps open, but nothing else sits in your window BUT the app you're using.  So you want to go to iTunes?  So click on it in the dock and Safari vanishes and iTunes emerges by itself.  No other windows.  What could be simpler?  (This app is freeware known as ISOLATOR.)
    If you download and try ISOLATOR, you'll say, umm, okay, but wait:  sometimes I do want more than one window in view.  Okay, fine, turn it off then.  From the handy menu bar menu.  I find that 98% of the time I need ISOLATOR on.  Mileage may vary.
    So let's recap.  One third party software removes distracting desktop clutter, the other removes distracting app windows.  Both can be toggled on and off from the menu bar.  One is free, one costs $2.  These two solutions remove the only real feature of FULL SCREEN APPS and make SPACES and it's newfangled cousin MISSION CONTROL pointless.
    Need that last one explained?  Well, what's Mission Control but a variant of spaces?  To invoke MC and switch to the needed window are those same two annoying steps Spaces added into the mix.  Nothing was fixed.  Plus, like spaces, you must invest time and energy organizing such spaces.
    Why bother?  And so I ask again:  can somebody who's read and tried the above carefully explain to me why Mission Control, Launchpad, and Full Screen Apps are really needed at all?  (Outside of small screened Macs.)  Doesn't the dock and these two sharewares together solve most problems?
    Am I missing something?

    I agree with everything you said about full screen apps, mission control and launchpad. For apps that made sense to run full screen, they already could under SL. Launchpad is totally unnecessary and Mission Control is a mere shadow of Expose and Spaces.
    However, I feel you have not given due credit to Spaces. The point of Spaces is to let one organise logical desktops for different tasks, not just a way to reduce the number of windows on display. For example, I have a Space for software development where I run Xcode and the iPhone simulator, a Firefox window showing perhaps documentation or some other websites pertaining to software development, a Finder window that is opened in the folder with my design docs. I have another Space where I have the remote login sessions, yet another Space with another Firefox window where I do general surfing and emailing. I can switch between these spaces using a keyboard shortcut, which is much quicker than having to lift my hand off the keyboard, move it over to the mouse, move the mouse pointer over the Dock, find the app and click on it, only to find that it has switched to the wrong window of the app.
    Without Spaces, organisation of my desktop is disrupted each time I want to switch task, whereas Spaces allows me to drop everything I am doing, go and do something completely different for a while and go back to my exact previous environment. I have a 27" iMac so am not short of screen space but I use Spaces extensively. BTW, switching Spaces using a keyboard shortcut is a lot faster on SL than the equivalent on Lion, thanks to the gratuitous screen animation of the latter.

  • Mission Control Crashing? This solution worked for me

    The first OS I used from Apple was Panther. Since then, I have had 3 machines and I never did a fresh install. I simply upgraded from one release to the next.
    I never had any issue, but with Lion, things were different.
    Lion installation process is full of rough edges and I lost many tweaks I have done on my OSX all these years, several icons were missing on Finder, several apps missing from the Dock and Mission Control was not working after the installation.
    I banged my head on the wall for 24h until I found the culprit and Apple should test this better.
    Here is the solution that worked for me.
    The first test you should do is this:
    1) create another user on your system
    2) login to that user and see if Mission Control works there
    3) if it works, congratulations and welcome to my private club: the Mission Control Crashers Club.
    If MC works on the other user, the problem is with your account. So, continue reading this...
    Do you have experience dealing with terminal and unix?
    If you open a terminal window and type
    cd ~  (enter)
    ls -al .*   (enter)
    you will see a list of all invisible files and directories that are stored on your home directory.
    look at the names and dates you see there. In my case I have located files and directories created in 2008 (on another mac I don't even have anymore) and I also saw files and directores belonging to apps I have removed a long time ago.
    look at each file or directory that starts with a point (= invisible).
    if you locate a file you want to remove, type
    rm .aaa
    where aaa is the file name
    if it is a directory, type
    rm -r .bbb
    where bbb is the directory name
    when you feel you have removed all the old crap, log out and login again.
    Try Mission Control and Dashboard then.
    OBVIOUSLY, MAKE A BACKUP BEFORE REMOVING ANYTHING. DO IT AT YOUR OWN RISK.
    In my case, the problem was solved.

    Thanks for taking the time to come back and let us know - it is valuable to see when a fix has worked for someone.

  • Mission Control not loading

    Since upgrading to Yosemite, I can't load mission control:
    - The fingers up move on the track pad doesn't do anything.
    - The hot corners do not work.
    - When I select an app in the dock, it doesn't go to the right space anymore.
    - I can't add / remove spaces, the icons for it do not appear.
    When I try to load mission control nothing happens, it quits instantly: no error, no console output, etc.
    I have attached a trace of the app, in case it can help find what is wrong: http://pastebin.com/0FRFf3Q8
    I have no idea where to look!

    Can anyone run a trace of "Mission Control" for me? I want to see what it does as mine is not working at all.
    The steps are as follow:
    1) kill mission control so it's not running
    sudo killall "Mission Control"
    2) open a shell and type:
    sudo dtruss -afs -n "Mission Control" > ~/Desktop/trussoutput.txt
    3) load mission control
    by clicking on the icon..
    The output of the shell will go to a file called 'trussoutput.txt' on your desktop; if you could send me that file, or put the contents on pastebin.com, it would help be greatly in trying to figure out what is happening. Mine seems to be stopping abruptly after loading the GSS library...
    thanks!

  • Unwanted Mission control openings with mouse movement

    Many times Mission Control will open when I make a fast movement up or down with Magic Mouse. It's happening more and more, and very annoying.
    ais there any way to turn it off? I can't figure out what iscausing it.  Thanks - Rick

    It's caused by a double-tap with two fingers on top of the Mouse.
    You can turn it off in System Preferences > Mouse > More Gestures tab > uncheck Mission Control.

  • [bug] Can't open new desktop from mission control if dock is on the right side

    I can't open new desktop from mission control if dock is on the right side

    I recently moved my dock to the right so I didn't know the + sign would switch sides. I normally run around that many too depending on how large of a stack whatever I am programming is using.
    Anyways, thanks for the help

  • How can I fix Dock/Mission Control/Launchpad? (Glitch)

    General Description
    Mission Control and Launchpad glitch when invoked (whether by using the mouse or trackpad gesture). They seems to crash or quit, and then relaunch themselves (/itself - all the same app?), I know this because:
    they both, as well as Dock, become unresponsive;
    the desktop background images disappear temporarily (being replaced by blank light or dark grey);
    the Mission Control animation stops/freezes and does not execute properly (the windows stay still);
    Dock becomes unresponsive as well as Launchpad.
    This happens a lot (every other invokation) and seems to be random; it's annoying and is ruining my workflow, since I am a heavy user of multiple desktops.
    Behaviour
    I usually have over ten desktops, all with active apps open at one time; when it glitches I can't even open or switch applications, though I can use the ones that are on the current desktop (if was trying to use Mission Control).
    There is no correlation with the glitch and the amount of applications open, or how much RAM or CPU is active (still happens with only a few light apps open and a few desktops).
    It does not matter whether I am using more than one monitor, the glitch still occurs.
    It does not happen due to a particular open application, as I have tested with nothing open at all straight after a restart.
    Possible and tested causes
    An application might be corrupting the glitchy app(s), since the disk breaks after being repaired in Safe Boot mode. Once the disk has been repaired, the glitch doesn't seem to occur until a few applications have been opened, though I haven't tested this much. (I am suspecting TheBrain, but not sure. Other potential culprits: Chrome, Mail, Firefox, Spotify, Skype, Dictionary, Activity Monitor, Finder).
    It isn't the operating system itself because I have reinstalled it from Safe Boot mode, and yet the glitch persists.
    The application(s) affected by the glitch may be corrupted, and need reinstalled - that is, if they weren't already by reinstalling the operating system (they are in the '/System/CoreServices' folder).
    Not-so-possible:
    I doubt it is a virus - it would be a pretty pointless glitch for one to cause.
    I have Time Machine running most of the time, but I have no reason to believe that is the cause.
    I am using a NEET mini display port to HDMI adapter for my second monitor (no idea how that could be causing the issue).
    Help
    Any ideas on what I could do to fix this?
    And does anyone know how to reinstall Mission Control, Dock and Launchpad (I think they are all part of '/System/Library/CoreServices/Dock.app')? This might be worth a try.
    Specifications (just in case)
    2010 Macbook Pro
    2.8 GHz Intel i7
    8 GB memory
    500 GB HD (two thirds full)
    Thanks for any help!

    One thing I'd like for you to try: Create a new user account. Log into the new account and see if the same problems persist.
    Many times such crashes are the result of corrupted preference or cache files. The above will eliminate these in the user account but not at the system level. So, I suggest you use a utility such as Lion Cache Cleaner 6.0.11 or Purity 1.10 to clear out cache files at the system level. I've never used the latter software but I, personally, use the former one on my computers.

  • My MacBook Pro is stuck in Dashboard overlay.  When I opened the case this morning there it was.  I did not enter this mode and cannot get out and back to the desktop.  I have tried Mission control, but it will not open, escape doesn't work either.

    I have a MacBook Pro running Yosemite.I did not shut down the computer last night.  When I opened the computer this morning Dashboard in overlay was on the screen.  I have not been able to get out of dashboard.  I have tried esc, F12, and accessing System Preferences in the Dock.  I clicked on Mission control and nothing changed.  Help be get back to my desktop.

         Did you try restarting the computer?
        Delete com.apple.dashboard.plist file.

  • Dock Crashes When Accessing Mission Control

    For some reason, the Dock crashes and reboots every time I try and get into Mission Control. The log is posted below from Console.app. Anyone know why this might be happening? I'm on the latest version of Mavericks.
    The only strange thing that's happened to my OS is a bash script that ran without admin permissions that started deleting files (there was a bug in the script I wrote) off my drive in alphabetical order. Mostly that just screwed up some applications like the Adobe Creative Suite and Autodesk Maya, but it perhaps had an impact here?

    Hi ..
    Might be corrupted dock preferences.
    Open the Finder. From the Finder menu bar click Go > Go to Folder
    Type or copy paste the following;
    ~/Library/Preferences/com.apple.dock.plist
    Click Go then move the com.apple.dock.plist file to the Trash.
    Restart your Mac then try Mission Control.

  • Why is iTunes window open in every mission control window

    I have a 27" iMac with the latest Mac OS and the latest version of iTunes. I have my iTunes library installed on an external Hard Drive. When I open iTunes, every mission control window has an open iTunes window? 10 screens 10 open iTunes windows? This is very annoying! How can I fix this so only one iTunes window is open on one mission control screen?

    Hey llsorens,
    Thanks for the question.  Take a look at the resource for Mission Control below.  It sounds like in your Mission Control preferences, you have the options set to All Desktops, which means the application (iTunes) will appear in every space.
    OS X Yosemite: Work in multiple spaces

    Assign apps to spaces
    If you assign an app to a particular space, it opens in that space by default.
    Press and hold an app’s icon in the Dock. You may have to first open the app from Launchpad to see its icon in the Dock. 
    From the shortcut menu that appears, do one of the following:
    Have the app open in the current space: Choose Options > This Desktop. 
    The app appears only in that space. However, if you open the app in full screen, it appears in its own space. 
    Have the app open in the current space on a specific display: Choose Options > Desktop on Display [number]. 
    Have the app open in every space: Choose Options > All Desktops. 
    The app appears in every space.
    Have the app open in whichever space you’re using at the time: Choose Options > None. 
    In Mission Control preferences, you can also specify that, when you switch to an app, your desktop should switch to a space with open windows for that app. To open Mission Control preferences, choose Apple menu > System Preferences, then click Mission Control.
    Hope that helps ...

  • Documents visible in mission control but won't open

    I am having difficulty accessing open files.
    When I attempt to open a power point presentation from the Finder, power point opens, and I can see the file opening but then nothing appears.
    When I then go to mission control I can see the images of all the power point presentations I've been working on, but when I try to click on any of them my desktop opens but none of the powerpoint files are there.
    Does anyone have any idea how or where I have hidden them?
    They are completely inaccessible right now, even though they are all visible in the mission control window.
    Thanks for any help!
    I'm using a Macbook Air, Lion 10.7 and Office for Mac 2011

    Try this:
    Right-click the Powerpoint icon in the dock and choose:
    Options > Assign to Desktop > None

  • IMac does not show open windows in Mission Control

    Ever since I installed Mountain Lion on my 2008 iMac 24", I've had a problem in Mission Control where the Desktop that the OS boots into will not show a preview of any windows open in that desktop. I have a new 2012 MacBook Air that does not have this problem. I thought the 10.8.1 update might fix it but no luck. Originally, I upgraded from Snow Leopard but eventually did a clean install and manually restored documents so that all the preferences/system files would be fresh, but still no luck.
    A screenshot of what I mean is attached. I have FF open in desktop 1, but it does not show at the top, whereas all other desktops show window previews.
    Has anyone else had this problem and have you managed to fix it?

    I dont use the Trackpad, just a mouse. Moments after I typed it, the answer was suggested already:
    CTRL+Mission Control button does exactly what I want.
    Is it possible to reconfigure this shortcut to the Snow Leopard way? (Pushing and holding the mouse button on an app in the dock for the same results)
    Thanks,
