Auto-detect displays not working in mountain lion

I keep a VGA projector connected to my laptop and Mountain Lion seems to believe that it is on all the time. Thus, I'm stuck with windows off screen. Anyone discover any fixes? No menu bar monitor ajustment preferences appear, nor does detect displays work through system preferences. I have a late 2008 macbook pro 17" with a DVI to VGA adaptor. Thanks

In System Preferences > Displays > Gather Windows.
You could also switch to mirror mode by Pressing CMD F1 to reclaim or end tasks then press it again to return to extended desktop mode.

  • IMac external display not working with mountain lion

    I have an iMac 3.4 Intel Core i7, have used an external monitor for a program for ever.  Upgraded to Mountian Lion and no more external monitor.

    Update/Fixed - I talked with Apple support via phone since I had 90 days of complimentary support.  After describing my troubleshooting the rep recommended reinstalling 10.9.  I did that this morning and the remote monitor is back in service.  So it appears something broke in 10.9 that is fixed by the re-install.  It would be nice to know if it's a simple preference that could be trashed.  But it looks like hardware is not the issue. 

  • Logitech Quick Cam pro 9000 is not working with Mountain Lion's dictation

    The Logitech Quick Cam pro 9000 is not working with Mountain Lion's dictation.
    Opening the dictation system preference panel makes the system preferences crash...
    The mic of that camera is the only mic I have.
    I own a Mac Pro and an old Cinema Display which has no built-in cam/mic.
    Anyone having the same issue?
    I hope this is gonna be fixed with 10.8.1.

    Hello, thank you for responding.
    Unplug and plug in back the camera does not solve this problem. I tried that before.
    But what worked was to start photo booth. Don't really know why.
    So after every restart of the mac I have to start photo booth and dictation with the QuickCam is working. ^^

    Dashcode is not working in Mountain Lion. I tried updating to Xcode 4.4 and it still did not work . . .
    I use dashcode for most of my coding needs, so it is very important to me!

    I have the same problem too. dashcode shows up in the finder but its just a question mark (see screenshot). Anyone found a way to address this?
    Thanks!

  • Remote desktop not working on mountain lion

    My ARD does not work on Mountain Lion. The software opens but all I get is the menu at the top, and my only working option is to quit. I spoke to Apple support and they suggest (as they usually do) to reinstall the whole operating system, but I can't accept this as a valid answer as everything else works. There must be a way to fix this without having to reinstall a machine that came originally with Mountain Lion!

    I was able to fix my issue by just uninstalling ARD (I used AppZapper) - and just reinstalling it - no "Archive & Install" required - best of luck with your situation!

  • CS4 "Save as Adobe PDF" not working in Mountain Lion

    CS4 Save as Adobe PDF not working in Mountain Lion
    Just bought a new Mac with mountain lion, installed CS4 design premium twice trying to fix this. When you go to "print" then "Save as Adobe PDF" the process fails with a pop-up saying "An error occurred while saving the PDF file". I can still do the standard "Save as PDF" - but that usually results in a file size 10x larger than Save as Adobe PDF so it won't work for me; I need the small file sizes of Save as Adobe PDF.
    When I go to Help > Repair Acrobat Installation it seems to be recognizing a repair needed with Adobe PDF Printer (see screenshot below); but when I go through the repair nothing changes it still won't work.
    Any help is much appreciated!

    "Save As Adobe PDF" works fine in Snow Leopard.
    Thanks for the link, but this is no help - I already have "Save As Adobe PDF" on the menu - the problem is when I click that it errors out...
    I just think its sad that Adobe charges people $2000 and provides zero support for future updates; when I buy an iMac for half that amount of money or an iPhone I get operating system support and bug fix downloads to deal with the latest internet advances for years to come - but Adobe apparently takes your money and says sayonara! Is it really that hard to provide updates on $2000 worth of software for say 24 months??

  • HT1338 preview does not work with mountain lion

    I updated my mid 2011 mac mini to mountian lion and i find Preview and all of MS Office 2011 for MAC fails to work
    I can cut and paset the logs, but lets astart with assessing whagt does not work with Mountain Lion.

    Your profile lists a 2008 MacBook with Snow Leopard.
    I installed Windows XP into Bootcamp on my 2009 MacBook Pro (either in Leopard or Snow Leopard, I do not remember which) and I used it with Parallels 6.
    When I upgraded it to Lion, even though the Lion Bootcamp will NOT install Windows XP, my Bootcamp (and use by Parallels 7) survived the upgrade.
    It may be possible that it will also survive and operate a future upgrade to Mountain Lion.

  • Why does snaps pro not work with mountain lion?

    I spent a lot money purchasing the pro addition only to be told that it won't work with mountain lion due to Apple's written something into the code that does not permit me to make videos with it. I even tried ot make a video of Indesign acting up so i could send it to Adobe support and it wouldn't allow me to. Is this the resaon it suddenly doesn't work anymore? Are there plans to fix mountian lion to allow me to use my software? Alternatively,, does Apple have something that does screen captures of videos?

    this is the repsonse form Ambrosia: (Not sure I understand it)
    As far as Snapz Pro X 2 functionality, some major backend Digital Rights Management changes enacted by Apple may be what is preventing you from recording movies you were previously able to record using our software. Basically, our program can no longer access videos before the DRM protections are enabled, unfortunately we have no control over these changes. Please see the following FAQ:http://www.ambrosiasw.com/support/faqs/products/snapz-pro-x /Why-does-the-content-of-my-capture-display-as-a-checkerboard
    BTW I am current on the latgest version.
    Does anybody know how to work around my problem? I need to be able to record videos on my computer.

  • Logic Express not working on mountain lion!

    i am having problems with logic express 9.0.0 which is not running on mountain lion 10.8.2.
    i have made an attept to try and get newer updates but before it gets anywhere this pops up
         " An eligible Logic Express Version was not found in
         the Applications Folder. This Update requires Logic
         Express version 9.0 or higher. "
    (i do not have the logic disks at hand)
              The message that pops up when i attempt to open logic
                   " you cant use this version of the
                    application "logic express" with this
                   version of OS X.
              you have "logic express" 9.0.0 "
    please help!!

    Hi
    First, you are going to need v9.1.7 or later with Mountain Lion (http://support.apple.com/kb/HT5421)
    Second
    To get the updaters to work several things MUST be correct:
    The Logic Application must be named "Logic Pro" or "Logic Express" (depending on which type you are working with) with NO Additional spaces or numbers in the name.
    The application must be at the root level of the Applications folder (and NOT anywhere else).

  • IMessage Not Working Since Mountain Lion Upgrade

    Since I "upgraded" my iMac and MacBook Air to Mountain Lion, iMessage delivery is hit and miss to the say the least from my iPhone 4S.  I first realised there was an issue receiving text messages whilst in the States and not connected to WiFi. Messages weren't even being received as text messages, even but would all come through as a flood from my girlfriend when I connected to WiFi.
    At the weekend she dropped her iPhone 4 and the screen is duff so she's swapped her SIM into a spare BlackBerry until it's repaired.  Gues what? She can text me but my 4S is still trying to reply by iMessage and none of them are being resent/sent as text messages.
    It's useless having a mobile phone that will effectively only communicate by voice and e-mail and no basic texting. It wouldn't be so bad if it actualy said the messages were failing.

    Were you running os x 10.6 before the upgrade?
    Anyway photoshop cs2 won't work on mountain lion because cs2 is a PowerPC application
    and mountain lion can only run intel applications natively like photoshop cs3-cc.
    If you were using 10.6, then you were using rossetta, an application that allowed some powerpc programs to run on an intel mac and mountain lion doesn't have rossetta.
    The current versions of photoshop available from adobe are photoshop cs6 and photoshop cc, but since cs2 is out
    of the upgrade loop now, so you need to either buy the full version of photoshop cs6 or subscribe to photoshop cc.
