Desktop background problems: 27" iMac/Mission Control

I've just installed a 27" iMac running 10.8 with 16 GB RAM. I use 4 desktops at a time with different backgrounds in each. When changing between e.g. desktops 2 and 3, via CTRL-right-arrow, Mission Control annoyingly flashes the desktop 1 background before replacing it with the desktop 3 background.
I have replicated the problem on the other 27" iMac's I have access to, and with a variety of desktop backgrounds (e.g. only the Apple provided ones)
and with various amounts of RAM (8 GB to 16GB). It is a consistent problem on all 27" iMac's running 10.8 as far as I can see.
Mission Control handled multiple desktop backgrounds flawlessly under my previous set up (iMac 21"/10.7).
Does anyone know how to fix this behavior?

After installing Lion os I cannot see my desktop 1 nor can I see my open windows when I go to finder, I just get the grey/black background that comes with mission control. Any ideas as to how to solve this problem?

The top picture is what my Desktop 1 looks like. And the picture below is what my desktop looks like after clicking mission control. Ive tried changing wallpapers, changing preferences, etc. and I still can't figure out what's wrong. As you can see, on mission control you can't see any of the open windows, or anything that I have placed on my desktop. Any ideas as to how to solve this issue?

Hello cor-el, thanks for your reply. I changed my settings for downloads to desktop and it has appeared on there. When I double click I am asked which program I want to open file. I click firefox and another box "opening install" says I have chosen to open the file which is an application and do I want to save it. This is the only real option so I press save file. I get a box saying this is an executable file which may contain viruses - do you want to run. I press ok and the final box showing C drive file name and desktop appears stating application not found.
This happens the same whenever I try to install.
To my untrained eye the application is not being recognised as an application and I cannot work out how to get it to do that.
My plugin is still showing as out of date.
Is there anything you could suggest. Thanks for your time.

I had been having a similar problem on Lion with Safari pdf files despite downloading the latest Adobe Reader XI.
I would constantly get the same messages - There was an error opening this document. The file is damaged and could not be repaired. And I would get a blank page when I tried to print the pdf if I tried printing from the Safari web page using File - Print from the top toolbar on my laptop.
Then I came across the grey Safari lozenge with action icons.
This allowed me, without downloading the pdf, to print the pdf file direct from the Safari page by using the Print icon on the grey lozenge that appears centrally three quarters down the screen.
Then I discovered that if I save the pdf using the Save icon from this same grey lozenge on the Safari page I can open and print this pdf version from my desktop.
I've tested it with a couple of different pdf files and these methods work using the grey lozenge icons but the same pdfs files don't work using File - Save As on the Tool Bar.

Desktop background problem

Hi
I have chosen to use a particular photo folder to use as desktop background for my Imac. I have also checked the "change image" and "random" boxes, every 30 minutes. As long as I keep the Imac running, everything is fine but as soon as for some reason, I reboot the computer, I get the original photo that came with Snow Leopard and I have to change the settings all over again as it had not remembered the information.
I have tried a few times to delete the finder's plist fife, to no avail. Is there something else I may try to try and fix it once and for all ?
thanks

I just created a new admin account, applied the same desktop background settings as my regular account and then rebooted to the newly created account. I was surprised to find out that it's the exact same situation with the new account.

Position of desktops keeps getting rearranged in mission control

I would prefer that the sequence of desktops remain the same in Mission Control so that I can always view them in consecutively numbered order when Mission Control is activated. For example, sometimes when I launch Mission Control, the desktop labeled "4" appears immediately to the right of the desktop labeled "1", so that "2" appears immediately to the right of "4" and "3" appears immediately to the right of "2". I can remove all but the first and add 3 more to get the expected order back again, but the same occurrence soon follows for no reason I've yet been able to determine. How can I keep them from jumping around?
Oops, sorry, I see something in the Mission Control System Prefs that appears to address this: Automatically rearrange spaces based on most recent use. Hmm, I thought they were called "desktops" now. Never mind.

In the Finder, hold down the option key and select Go > Library from the menu bar. In the folder that opens, select the file Preferences/com.apple.desktop.plist. Open the Info window. Do you have read & write access to the file? Is it locked? What is its modification date?

Does anyone a problem with lagging mission control?

Mission control (expose) on my MBP (8GB RAM) is lagging. Animations of transition between desktop and mission control mode is't continous. First I see animation of desktop (resizing and going to mission control view ), after that windows of appliactions are rearranged (resized and set to mission control view) without animation. Animation from Mission control mode to desktop lagging too
After instalation everything works fine. I noticed this error yesterday.

I'm having this exact issue. Late 2007 Santa Rosa MacBook Pro.
I made a video to show what's going on (the recording slightly exagerates how bad it truly is):
http://www.youtube.com/watch?v=sYxcmsvMKlY
The video was made on a 10.6 to 10.7 upgrade install.
I went in and did a complete wipe + install from a USB drive, and the issue was fixed for about a week before it came back. Is there possibly a .plist file or something we can try deleting to narrow down the issue?

Desktop wallpaper overlapping Spaces in Mission Control

This is a weird one. Since upgrading to Mountain Lion I can't access Spaces in Mission Control properly because I have desktop wallpaper from a previous space overlapping most of the spaces at the top of Mission Control, i.e. desktop wallpaper from Space 1 carrying over onto Space 2 and blocking out the spaces at the top two-thirds of Mission Control (see image).
This currently occurs with my MBP hooked up to my Thunderbolt Display. (Haven't confirmed this behavior on the MBP alone yet.)

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Problem to get Mission Control 3.0.1 running with JBoss 4.2.2GA

Hello,
I'm using JRockit R27.04 to run JBoss 4.2.2GA with the following VM parameters:

It was a good attempt, but I'm still getting the same exceptions.
I tried to create a new service file, and it was successful deployed:
<?xml version="1.0"?>
<server>
<mbean code="bea.jrockit.management.JRockitConsole" name="bea.jrockit.management:type=JRockitConsole">
</mbean>
</server>
After it I opened JBoss JMX Console and I saw the following mbeans published:
bea.jrockit.management
type=Compilation
type=DiagnosticCommand
type=GarbageCollector
type=JRA
type=JRockitConsole
type=Log
type=MemLeak
type=Memory
type=PerfCounters
type=Profiler
type=Runtime
So, it appears that all jkrockit MBeans are published, but the problem persist.
Any other suggestion?
Thanks,

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.
    Quit all applications.
    Option click the "Go" menu in the Finder menu bar.
    Select "Library" from the drop down.
    Library > Preferences > com.apple.dashboard.plist
    Right click on it and select "Move it to Trash".
    Restart.
    If this doesn’t help, Put back the com.apple.dashboard.plist
    Right click the Trash icon in the Dock and select “Open”.

How do I create multiple desktops in 10.8.2 Mission Control?

I've been given to understand that in 10.8.2, Mission Control allows for up to 6 desktops. If this is true, how does one create and maintain them? I can't find documentation anywere--or am I just on a wild goose chase?
Thanks...

I'm not sure what the limit is, but it's a lot more than six.
Move the cursor to the right of the rightmost desktop. A dark "+" (plus) icon will appear.
Click it!

Mavericks showing 3 desktops when I use the mission control

Hi Guys,
I was hoping someone could give me some advice. I have y cintiq plugged into my macbook pro. Everything works fine but when I used mission control it shows I have 3 desktops active. How can I reduce it to 2? Not only is it something I believe should not be there, I also feel it may be eating up memory.
Any advice very appreciated, Thanks.

Ah, I figured it out. As I hovered above a window whilst using the mission control action I noticed an 'x' in the corner of the display I didn't want and closed it. Hope this helps incase anyone had the same enquirey

[SOLVED] Xfce 4.12 desktop background problem

Problem solved. Problem was with Linux kernel and Intel graphics card. On boot I was getting this error : [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe A
I downgraded kernel to version 3.14.6-1, now xfce desktop looks OK and no errors during boot.

Desktop background disappears, Mission Control doesn't work correctly

Sometimes it happens that my desktop background completely dissappears, and Mission Control stops working as well.
It seems to happen when I open a new window in a fullscreen app (like Safari), and while it's opening I switch to another space.
Whenever this happens, my desktop changes to the Dashboard background, and Mission Control doesn't show the other spaces anymore (but you can see active windows in your main space). I've added pictures below.
I can still swipe between spaces, my dock still works and all apps still work in all spaces.
Any way to fix this without rebooting? To avoid this happening (apart from me being more patient)?
This is my desktop at the moment:
And this is Mission Control:
I am using: Macbook Pro 5,4
OS X 10.7.1
2,53 GHz Intel Core 2 Duo
4 GB 1067 MHz DDR3

I am experiencing the same thing as most of us, exactly as explained by - Acid_Raccoon.
UK-Max - This is not just a specific problem involving external screens. The dissappearing wallpaper, and loss of function of mission control (do not show spaces, but you can click in empty area where it should be located and it actually works as normal) occurs also when there is no
external screen input involved - You have to restart computer for it to return to normal. As a matter of fact, I am experiencing it right now for the 10th time in 1 week period, and it´s quite annoying. I would guess more than just a few people are experiencing this, and as postmechanical mentioned about having a brand new computer - this shouldn´t occur, and if so should get a fix immediately.
Over time, I have experiencing other system problems produced from installing OS lion. Sure it deliver a few smart, and smooth features, but since more and more bugs are discovered (and not fixed by apple), I am considering returning to snow leopard. For instance, sometimes when my computer goes into screensaver, it can shift to a picture of pixels (black&white) in 4:3 screen ration. This has never occurred before installing Lion. Another thing which is extremely annoying is that since installing lion, my computer refuses to go to sleep when I close my lid. Nothing happens, and it just stays on. I have to manually select in apple-menu to sleep.
I really hope Apple take these notes people have mentioned in this forum (and others) seriously, and fix them. I really hope Apple show more custumer service-spirits, than Apple´s lack of hardware-quality. (I have owned 4 apple computers(1 powerbook G4, 1 macbook & 2 macbook pro), brand new, and 3 of them have experienced hardware-failure on more than one occasion in less than a year. The one that didnt required service was my powerbook G4 titanium, released in 2001, and kept going for 4 years straight without any problems.) (Actually, the last one experienced 3 times in-a-row mother-card failure). I only go for Apple´s products due to its smart and clean features (and seriously PC is not an alternative if you want to stay mentally healthy), but what I´ve been reading on multiple forums over the web, more than a few, experience occuring hardware problems with their Apple computer.
I guess this is the result of Apple trying to push for higher revenues. If Apple keep go in the same directions as it has been doing in the last 4-5 years it will be its doom, and loose the customers that once caught the Apple-wave due to it´s innovative and personal aspect, but most important - it´s superiour quality it once had! Apple´s products is quite expensive, and thus should be combined with its smart and innovative system, along with lasting quality. But if $ revenue is the only thing that keep Apple going nowdays, and produce smart product that is meant to last for only 2-3 years maximum, it is deeply disturbing and the company will loose track of what stevie was initially producing - clean, smooth system (just works, no migraine), with everlasting quality far seen in PC-world. Apple - please consider !

I have the mission control desktop and then desktops 1 through 7.
I have them all opening up various applicaitons, but even though I move the app to the desktop I want, and I shut down with the app open in that desktop, on restart it opens up in the wrong desktop...always the same one, but always the wrong one.
iTunes - I put it in Desktop 7, its there when I shut down. It always opens up in Desktop 1. I don't have trouble with calendar, mail, addressbook.
Also, sometimes 'finder' folders that I have left open in a specific window when I shut down do not open up on restart. They do sometimes, but most of the time not.
Thanks!

If you are running the program ctrl+click on its dock's icon.
Choose Options -> This Desktop
If you also want to always keep in sequence all spaces, in System Preferences uncheck

How can I switch the first desktop in Mission Control?

I can switch between all others just fine. I've messed around with Mission Control in System Preferences but I haven't found anything useful. Right now if I want to switch say the first and second desktop, I have to...
enter mission control
drag app A from desktop 1 to desktop 2
enter mission control
drag app B from desktop 2 to desktop 1
enter mission control
drag app C from desktop 1 to desktop 2
Which is extremely frustrating.

I'm not sure I understand exactly what you are trying to do because the dragging applications around is making me unsure. I'll give you some information and maybe that will help me help you.
You don't have to go to Mission Control and move applications to change desktops. Three ways to navigate between desktops:
1. Hold down the control key and use the left/right arrows to change desktops.
2. Open Mission Control and click on the desktop you want to have showing.
3. Go to System Preferences/Keyboard, unlock if locked and select Mission Control. Check the boxes "Switch to Desktop X."
Two other possibilities I can think of:
1. Do you want to assign applications to a certain desktop?
2. Do you want the desktops to always be in the same order?
