Blank screen in Expose and Spaces preferences

When I open expose and spaces in system preferences all I get is a blak screen.  I want to set some application preferences for spaces.

I called Apple support and they were able to help me.  Here's what they had me remove:
com.apple.dashboard.client.plist
com.apple.dashboard.plist
com.apple.dock.plist
com.apple.finder.plist
com.apple.symbolichotkeys.plist
my home/library Caches folder
the root Library/Caches folder
I rebooted and my Mac was back and running normal.  I think that /Library/Caches removal was the key part but I can't say for sure.

  • Expose' and Spaces preference plane is blank

    I upgraded my original core duo 20" iMac to Snow Leopard last night and it mostly went fine.   I did need to repair permissions to get the 10.6.8 combo update to install properly but that was the only hiccup I noticed at first. However, after a few minutes of usage, I noticed that my Expose' and Spaces preference pane went blank.  I was able to use it upon first boot but after a while I tried to go back in and click on the pref pane and got nothing aside from the message that the Expose and Spaces preferences were loading.  I clicked again and the window appeared but was blank.  Here's what I've tried so far.
    I logged out as myself and logged in as my wife and her preference pane appears without a problem.
    I repaired permissions several times including from a boot CD.
    I removed the relevant cache and plist files from my Library folder.
    I was able to get the pref pane back for a while but honestly I don't know exactly what I did to get it to come back.  I believe it was after I removed my com.apple.symbolichotkeys.plist file but I can't be totally sure.  One thing I noticed was that after removing com.apple.symbolichotkeys.plist, the file did not come back on it's own after trying to edit the preferences.  I even copied the com.apple.symbolichotkeys.plist from my wife's Library but that didn't seem to help (I'm still somewhat of a new Mac guy so I don't even know if that is a viable solution in the first place.)
    I've seen other people experiencing problems with blank preference panes but it doesn't seem like their solutions are relevant to my problem.  Also I would have thought that there might be a corrupt pref file somewhere but the fact that the behavior is normal under my wife's profle seems to suggest that all is well at the system file level.
    Any help is, of course, greatly appreciated.
    Regards

  • Cant find expose and spaces in system preferences

    I cant seem ti find "expose and spaces" in system preferences.  Can anybody help please?

    Welcome to the Apple Support Community!
    If you upgraded from Snow Lepoard OS 10.6.x that had Exposé and Space, then those two have been integrated into Mission Control in Lion OS 10.7.x. You can learn more in the Apple KB article Mac 101: Mission Control. Mission Control is in System Preferences. Another source of info about Mission Control, Exposé and Spaces is from the Help menu in the Finder. Just type any one of those elements in the search box and you should get a few articles that are connected to each other.

  • Dashboard Preferences: Why does Mac OS direct me to Expose and Spaces Pane?

    When I right click on the Dashboard Icon in the Dock and select "Dashboard Preferences..." I am directed to the System Preference pane for Expose and Spaces.
    This doesn't appear to be logical.
    Is there a true "Dashboard Preference" pane?

    Hello,
    when I look for list.plist the directory
    arrow indicates there are files but no files show in
    the directory.
    Files named list.plist or files which name contains list.plist ?
    I have no file named list.plist since I trash the one I told before.
    Is this similar to the "hide system
    files" option in Windows? If so, how do I turn on
    the view to show the file? Thanks in advance...
    On Mac, if a file is hidden* there is a good reason... so don't try to make them visible except if you know exactly what you do !
    * In general, a file which name begins with a dot is invisible in Finder.

    Priscilla,
    if your Mac is still in warranty, then you should contact the Argentinian technical support service. If it is out of warranty, then we can try to lend a hand. (We’re just fellow Apple product users here.)

  • My iPod touch 3 has a blank screen (luminescent gray) and is totally unresponsive.

    my iPod touch 3 has a blank screen (luminescent gray) and is totally unresponsive.

    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Unable to map expose and spaces keys to function keys on unibody macbook

    Hi all. I just bought a unibody macbook and wanted to add the spaces key to view all the windows in all spaces to the F5 key, and another expose key to F6. I went into the control panel under "expose and spaces" and "keyboard shortcuts" under "keyboard" and tried to set these keys. But it never actually accepts any of the settings I make. I put the settings to make them f5 and f6 but nothing happens when I press the keys. I know about the gestures and the hardcoded keys that are predefined on the macbook, but none of these allows me to use spaces to look at all the windows.
    What's going on here, have they made it impossible to set your own keys for these things now? Is f5 and f6 just totally unusable now? Is there a workaround?
    This is really annoying. Any suggestions?

    haha, I just figured it out after I posted it. It's Function-F5 that it get's mapped to even though it still says only f5. I don't know why it doesn't just say that in the first freaking place, but whatever.
    Does anyone know of a way to do this without having to use function-f5 and just mapping it to plain old f5? As far as I can see the key is just sitting there unused..

  • TS1906 Ical frozen - blank screen, no data and unresponsive buttons

    After installing the last update, Ical is frozen - its shows no calender data, and the buttons for day/week/month don't work. I restored the calender data from my last time machine backup, after which it worked for the first time I opened ical. The next time I opened it, I was back to square one - no data, and unresponsive buttons (also not able to change the view over the top bar menu) and then I even got a blank screen (where the calender data should be).
    Luckily my data still shows on my iphone and on my google calender. Its only on my Mac (version IOS 10.6.8) that Ical (version 4.0.4 (1395.7)) isn't working. I believe this is a bug of the actual Ical software, rather than my data.
    Anyone have similar experiences, or an idea of how to fix this? Thanks.

    I had the same problem with my Radeon Mobility U1.
    The solution is to downgrade the xf86-video-ati driver to the version 6.7.195-3 and it should work flawlessly.
    Make sure pacman and/or yaourt don't upgrade this driver inadvertently to this latest, buggy version, until a fix is released.

  • Has Expose and Spaces been changed?

    I loved spaces because I could hit fn f8 to see all 6 different spaces. Well now that doesn't happen anymore it just switches between all 6 spaces in order 1-6. Its very fustrasting not being able to drag the programs you want into the correct spaces or even just switching through them anymore as i don't remember which space i put it on. How do i get it back to the way it was before so i can see all 6 spaces instead of it just switching in order of the screens? To active spaces my hotkey is f8. put it acts like the hot key to switch between spaces when its not even on that key.

    Update, just restarted my computer to get the newest updates now fn f8 only takes me to screen 4 and safari is on screen 6 -_-

  • Blank screen orange wifi and mute lights

    Hello,
    I have a Pavilion Dv4 laptop that does not boot. It seems to be in hibernation with the wifi and wan lights in orange.
    I can hear the fan spinning. It spins and then stops and spins again. The DVD light comes on and the numllock and caps locks blink in sequence of 1 continuously.
    Please help me! I need my laptop to use.

    Hi jendy,
    Welcome to the HP Support Forums!
    I understand that you are getting no display, but the Caps lock and Num lock LEDs are blinking. I am happy to help you with this. The below document shows the meaning of the error codes.
    Blank Screen LED Error Codes
    If the lights are flashing just once and then repeating that sequence, it indicates that the CPU is not functional. If that code is correct then I recommend calling the support line. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

  • Blank screen between preloader and beginning of SWF movie

    I'm having a problem with a published SWF. A long lag time is occurring between the end of my AS3 preloader and the beginning of my SWF movie. Once the preloader disappears, the SWF screen goes blank for up to 10 seconds before the movie begins. I've monitored the SWF's download progress using Firebug, and the preloader disappears once 45% of the SWF has been downloaded, as is to be expected.  But the movie does not begin until most of the SWF has been downloaded, which causes the 10 seconds of blank screen. After reading some blog posts, I suspected that the audio embedded in the Captivate presentation was causing the SWF to download all of the audio before starting the movie. I followed recommendations to add a tiny amount of silence the beginning of each slide, but it hasn't resolved the problem.
    Does anyone know how to fix a long lag time between a preloader and movie? My SWF settings and other details are below. Thanks in advance.
    - Using Captivate 5
    - The presentation has 18 slides.  Each slide has one JPG and one audio clip.  (The audio clips were imported one at a time, instead of importing one large audio file and having Captivate spread it across multiple slides.)
    - Each slide is .4 seconds longer than its audio clip, leaving .2 seconds of silence before and after the audio clip. 
    - SWF Size and Quality are set to Low
    - Audio Quality is set to MP3, 64Kbps, 44.100 KHz
    - Using AS3 preloader set to 45%
    - The SWF is hosted on a web server and is viewed via the htm file that is generated when the SWF is published.

    Hi Vikranth,
    Thanks for your help.  The online SWF is here:
    http://leo.lincolninst.edu/eTeach/captivate-tests/inside-focus-area/new-opt-img-mp3-chunks -full-2/inside-focus-area-new-opt-img.htm
    I've also posted the same SWF with a 15% preloader here (the smaller the preloader percentage, the longer the blank screen):
    http://leo.lincolninst.edu/eTeach/captivate-tests/inside-focus-area/new-opt-img-mp3-chunks -full-2-15/inside-focus-area-new-opt-img.htm
    I've sent the cptx file to your email address.

  • ITunes blank screen on search, and faulty History page

    Hello,
    I have an iPhone 4s with iOS 6.  Whenever I try to search in iTunes the results don't load and I'm left with a blank screen. 
    Also the History page seems faulty - after I clear my history there's no 'done' or 'back' buttton so I have to close and reopen the app.
    Any suggestions?

    Same here on iPhone 4. It works fine on my iPad 3. Rubbish again from apple. Featured stuff selected fine, it's just the search. Basically can't buy any film unless it can be found under categories or history

  • When I go to system preferences expose and spaces is not there for me as an option. What can I do to restore it?

    I have tried to fix permissions and restart and that did not help it show back up and I have also deleted the system preferences cache and still nothing. What can I do?

    I also miss the grid layout of spaces.  In fact, I'm considering downgrading back to Snow Leopard just to get it back.  I used to use command+arrow keys to move around in my grid of spaces.  I used to use a hot corner to initiate spaces, then another hot corner to initiate expose while "zoomed out" in spaces.  I used to be able to click any window of any app in any space and move it to any other space.  I used to be able to move an entire space to another location. 
    Now I've upgraded to Lion and I cannot do any of that.  Serious downgrade, serious loss of efficiency.  I've taken the time to learn how Lion handles all this.  I've taken the time to change options to try to make MC more efficient.  Simply put, it's a downgrade that breaks something great from Snow Leopard.
    For example:  Initiate Mission Control while on desktop 1 and I see a window on desktop 2 that I want on desktop 3.  In order to move that, I have to first switch to desktop 2, initiate MC, then move the app.  Not to mention, if that window were under another window, I'd not be able to see it at all! 
    For example:  In SL, to go from space 1 to 9 on a 3x3 layout, I could use command+right, down, down, right.  On Lion, I have to use comand+right, right, right, right, right, right, right, right.  seriously?  Sure, I could use command+9 (if that's even where Lion decided it wanted to keep the app!), but I prefer the efficiency of using 1 hand to do the keyboard shortcut. 
    Tell Apple you want the option of having spaces in a grid again.  Who knows, maybe if enough of us do, they'll bring it back: http://www.apple.com/feedback/macosx.html

  • Blank Screens After Startup and Wake From Sleep

    About half the time I startup my Mac Pro or wake it up from sleep, the screen will go blank, usually about 20-30 seconds after video appears on the screen. The system seems to be running, you just can't see anything.
    I have had the screen go completely white, black or blue and occasionally, there will be a solid color with vertical lines throughout the screen. The only thing that will get display back is a forced restart of the entire computer.
    I've zapped PRAM and run run hardware test with no issues reported but the problem keeps coming back.
    I'm driving a Dell 2407 on my ATI 1900XT. Dell supplied a single-link DVI cable, could that cause issues with a dual-link port on the video card?
    Mac Pro   Mac OS X (10.4.9)   ATI 1900XT, 2GB RAM

    Intel Macs, especially MacBook Pros seem to be notorious for sleep issues...either not sleeping when supposed to, or not waking up from sleep properly.
    My MacBook Pro has come out of the brief case hot as heck with a dead battery often enough, even with all the updates appled. If you listen to the MacBreak Weekly podcast, that's a common complaint of Merlin Mann, who can't figure it out with his machine, and he's no dummy when it comes to Macs. Not very encouraging, is it?
    Still, what I would try is reinstalling the OS X 10.4.9 update. I've often read/heard on podcasts that it's better to manually install the larger Combo version of the updates. That seems to have fixed problems for me in the past.
    Get the Intel 10.4.9 Combo Update here: http://www.apple.com/support/downloads/macosx1049comboupdateintel.html
    Good luck.

  • Can expose and spaces be installed on Mavericks?

    I recently updated my OS from Snow Leopard to Mavericks.  I am sure there are some nifty things that this new OS can do, like iCloud synchronization, but Apple seems to have done away with some features that I really found useful, like Spaces which I used all the time.  Is it possible to install Expose & Spaces on a Mavericks equipped machine?  How would that be done?
    Or is there a new feature that does the same thing that I have missed?
