    Hello rodamitjr,
    It sounds like your iMac display will turn off unexpectedly, but you can tell the computer is still on because you hear audio.
    I found an article with steps to troubleshoot issues with displays.  This article is for internal and external displays, so you can skip any steps referring to an external display.  I recommend reviewing the full article, but this step specifically stands out to me for the issue you described:
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    You can find the full article here:

  • What do I do to straighten out this problem... When I try to access Firefox after having logged out of a previous session I get a msg that Firefox is still running and I have to restart the computer in order to access internet.

    What do I do to straighten out this problem: When I try to access Firefox after I've logged out of a previous session I get a msg that Firefox is still running and I have to restart the computer in order to access internet...

    All you need to do is wait. While Firefox appears closed, it's not. It doing house cleaning. Cleaning out cookies and cache. How long it takes depends upon how much garbage you have collected.
    If you start the Task Manager and open the Process window, you will be able to see when Firefox has finished up and closed down.
    If you forced Firefox to close using the task manager, then the house keeping process seems to freeze up.
    Also, as you've already found out from the above link, some programs and plugins will prevent Firefox from closing properly. I've found this less common then simply being in a hurry. But you need to also consider it.

    I have a MacBook Pro.  When surfing the web it will eventually slow to a crawl.  When this occurs, there will be a small multi-colored wheel spinning until my latest command is handled.  What is causing this and is there a way that I can modify or prevent this from happening?  Is there a setting that will prevent this?

    When you next have the problem, note the exact time: hour, minute, second.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

  • I wiped my Mac desktop partition while using BootCamp. I want to just start over but how do i download snow leopard and start again?

    I accidentally wiped my mac OS partition while trying to expand the memory on BootCamp windows to play games. I did this through dropping memory on the mac then trying to merge the unallocated memory with windows 7. I'm now left with windows 7 and next to no memory, i dont have any data i care about backing up as i've only just got this mac (i bought it off a friend and they can't find the installation CD)  So i just want to start over but how can i do this?

    You'll need to find the disks, or buy new ones. Snow Leopard only comes on DVD.
    Call the Apple store and purchase SL for $29 while they still have some in stock. Prices have skyrocketed for SL retail disks. Going anywhere from $85 to $125. While you have Apple on the phone, make sure to have your Mac's serial number handy. This is important because the last retail release of SL was 10.6.3. If the Mac you now own came with 10.6.4 or later, it will not be able to use the retail disk.
    If that's the case, then you can use the serial number to get the correct replacement gray disks the Mac came with. It's not expensive to get them and would be good to have anyway since the retail disks do not include the bundled software such as iLife, Garage Band and a bunch of others.

  • After I exit Firefox, I keep getting messages that Firefox is still running and I have restart my computer. How can I avoid this from happening?

    This happens when I close the internet browser. When i want to go back on, nearly every time, I get the message that firefox is till running, close or restart the computer. Since i have closed it, I continuously have to restart my computer (or switch over to Chrome)

    Sounds like it is hanging when you exit and later try to restart Firefox.

  • When I close Firefox my computer says it is still running and I have to restart my computer to get Firefox to run...this is a first for me.

    Every time I close Firefox and try to restart it my computer leaves a message that I still have Firefox running and that it is unresponsive and needs to be closed. The problem is that there isn't a still-running Firefox to be found, consequently it is impossible to close and therefore impossible to open. I have used every form of Firefox and this is the first time this has happened. Please, please don't force me to use Chrome or iExplorer!!

    Start Firefox in Safe Mode (above). Wait a few minutes, then close Firefox.
    Is there still a problem?
    If you are still having issues;
    Type '''about:support''' in the address bar and press '''Enter.'''
    Under the main banner, press the button; '''Copy Text To Clipboard.'''.
    Then in the reply box at the bottom of this page,
    do a right click in the box and select '''Paste.'''
    This will show us your system details.
    '''No Personal Information Is Collected.'''
    Start your '''Computer''' in safe mode with networking. Then start Firefox.

  • When I close firefox I can't open a window again. It tells me that firefox is still running and I have to restart my system. This is a recurring problem on a brand new system and very irritating.

    I don't know what other details I can give you. I am not very computer wise. Just an every day web browser and emailer. This is a catch 22 problem. For example when I am installing a program; adobe flash player for example, it tells me to close firefox to continue and when I do I get the firefox is still running message even though there is no window. And so the installation isn't completed. I like firefox but this is a bit of a dealbreaker. hope you can help.

    * Try this.
    * Type in the address bar about:config.
    * Accept the warning.
    * In the page that appears, in the Filter box, type network.http.max-connections.
    * Change the value to 32 (which is probably set to 256 in your case).
    * Close the about:config page.
    * Restart the browser.

  • TS2972 I'm logged into my apple account in Itunes, my home sharing is on, still my computer and libraries are not showing.  This happend last week and I figured out that I wasn't signed in.  I'm signed in now, what is causing this?

    Can anyone help with the apple tv dilemma

    That's a very interesting find. A couple people have been reporting this. But we thought it was Google breaking that page on purpose because they plan to remove that special Firefox search page. They think it's too old and want people to switch to the newer one. But I'm still not sure why being signed into Google breaks that page (and signing out fixes it), I believe Google is at fault here and needs to update the code on that page.
    The new Google search page for Firefox is:
    <br>'''about:home'''
    Screenshot:
    <br> http://i.minus.com/iewA9S.PNG
    It's a special page built into the Firefox browser. That's why it has a weird website address that doesn't look like normal websites that use http://www., .com, .net, or .org.

  • My iMac will not boot up.  I  have a 3 year old iMac running   Lion.  When I push the power button I get the Apple logo, then the circular thing made up of small lines revolving iin a clockwise direction, then a progress bar which never fills in.

    The progress bar then disappears and the system never boots up.  How can I get this machine to boot without a start-up disc?
    Are there any keyboard shortcuts available?

    I think you'll need those grey original install disks as it sounds like your harddrive is corrupted.

  • My ipadmini is lagging in touch response. Sometimes the touch will just not work but other times it works fine. I am in Pakistan and have no authorised dealer here to whom i can take it. Also at times if i press a letter once it types it multiple times.

    Ipad touch problems

    Standard troubleshooting...
    1. Remove apps from the Recently Used (multi-tasking) list...
    - From any Home Screen, double tap the home button to bring up the Recents List
    - Swipe up on the app preview card to remove it from the list
    - Press the home button when done.
    2. Restart by pressing the sleep/lock button until you see the slider.  Slide to power off.  Restart by pressing the sleep/lock button until you see the Apple logo.
    3. Reset by pressing the home and sleep buttons until you see the Apple logo. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    4. Restore with your backup.
    5. Restore as new, i.e. without your backup. See how it runs with nothing synced to it.    You may need to try DFU mode (Google for it).
    6. If still a problem, it's likely a hardware issue.

  • Like an idiot, i bought a game for an ipad and only have a macbook air. can i somehow get the game to play on my air? or have i just thrown $5.29 out of the window?!?

    I recently bought a game for an "ipad", (thru itunes), when I only have a MacBook Air...I had seen where you could switch apps back and forth between devices, ad I thought I could do this. Is there a way to play the game on my Air laptop? Or did I just throw $5.29 out of the window? One more thing...it involved Facebook, and I don't belong...or want to belong!?
    I want to play Jeopardy, Wheel of Fortune, etc. ON MY MACBOOK AIR!?!???

    No way to play an iOS game on a Mac presently.
    I suspect if you contacted Apple's Customer Support and explained the situation they would refund or credit your account.

  • When TB is closed, the process is still running and I have to kill it to execute TB again ( W7 64 bits ).

    The problem appeared when version 31 was installed.
    Everything was Ok with previous version.

    Shut down hangs are often caused by Anti virus programs. Try placing an exception for your Thunderbird profile into your anti virus program so it does not scan the files every time they are opened or closed.
    But first try restarting with add-ons disabled from the help menu and see if it is an add-on that may be the cause.

  • While using my imac the display just cuts off whats causing this

    while using my imac the display just cuts off but the machine is still on and I have to push the power button a couple of times fir it to cut back on whats causing this?

    Hi keithfromcapitol heights,
    It sounds as if your iMac is going to sleep unexpectedly. Is this during use or after it has been left alone for a while (which can be normal if it is set that way?) If during use, I would suggest that you reset your System Management Controller, using the steps in this article -
    Intel-based Macs: Resetting the System Management Controller (SMC)
