Dear Jean:
It sounds like you are trying to get your external monitor to act as the primary viewing screen. For example it would have your Doc, Icons, Etc. In order to make the external monitor the primary screen you have to:
Open System Preferences.
Choose the Displays Icon
There will be several tabs to choose from pick Arrangement
Drag the toolbar to desired display
Let me know if this helps at all!

  • I need to connect a computer monitor to my MacBook Pro but have found that when using the mini display port to VGA adaptor the screen display on my macbook is very small font. Please what do I do to correct this?

    I need to connect a computer monitor to my mac book pro, using a mini display port to VGA adaptor. But have experienced a drastic reduction in font size on my
    Mac screen even before I have managed to check the result on the monitor screen. Please how do I compensate for this and restore my mac screen appearance?

    Welcome to the Support Communities!
    Resetting your computer's PRAM should restore your Macbook Pro's screen appearance.

    This article may provide some information about your Mini DisplayPort to AVI adapter.  Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?

    18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
    The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

    How can I detect displays?
    If the detect displays option is not available, hold down the Option key while you are in the Display pane.
    How do I select additional resolutions on my display?
    You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
    To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
    I hope this information helps ....

    Hi robfromkinglake west,
    Try and isolate the issue.  Check if it's only with this drive.
    Check the drive with Disk Utility

  • How do I connect an external microphone to a Macbook Pro with Retina display ?

    How do I connect an external microphone to a Macbook Pro with Retina display ?
    Alternatively how do I connect an audio input at a level that would normally have gone into a 'line input' socket ?

    Plug it into the linein/headphone jack if there's just one.  It'll switch between the two modes automatically depending on what you plug into it.

  • I would like to run a stock analysis program called Toolkit 6 on my Macbook Pro, but it only works on the Windows platform.  Is there software that allows me to run Windows applications on the Mac?

    I would like to run a stock analysis program called Toolkit 6 on my Macbook Pro, but it only works on the Windows platform.  Is there software that allows me to run Windows applications on the Mac?

    Yes it's MS Windows! You will need a license of MS Windows (preferable Windows 7) and from there you can decide on the strategy for running Windows on your iMac. You can use Boot Camp (you already have this) or you use virtualization software such as Parallels or Fusion. For your situation I'd recommend virtualization software. However for only one program I'd do some due diligence to see if there is a OS X version. You can start with the App store or simply use Google to search.
    Kappy has provided a good article on running Windows on a Mac and the various options. Here is the link:

  • I bought a new macbook pro but it doesn't want install os x mountain lion

    I bought a new Macbook Pro but it doesn't want to install os x mountain lion.
    I started the pc, filled in my language, chose "install os x mountain lion", it took a while, the pc restarted and asked the same things.
    What am I doing wrong? I can not go to my desktop.
    When the pc is restarted os x lion mountain is installed but i can't go to my desktop.

    Either that or they failed to install an OS on it before shipping.
    For a brand new Mac, I'd return it.
    Here is the article on Recovery, which is what you are seeing:  http://support.apple.com/kb/ht4718
    The hard drive should have a hidden partition which holds the standard Recovery HD. That is what you use to repair and reinstall. If that fails, or you have to replace the hard drive, you can use Internet Recovery which boots into Apple's servers.
    You could try Using Disk Utility to see if you can Repair the disk while booted into Recovery, but it just all sounds like a future of bad things if it starts out this way.

  • Hi..I have just recently got an iPhone and I had installed some apps already but now when I try to install and download any apps it just sits there on "waiting" and will not download.. Im able to erase it but no apps will download now. What Do I do?

    Hi..I have just recently got an iPhone and I had installed some apps already but now when I try to install and download any apps it just sits there on "waiting" and will not download.. Im able to erase it but no apps will download now. I have tried logging out of the app store but it still did the same thing. I also tried resetting it and that didn't work either. I've tried everything I can think of but still just sits there saying "waiting." what do I do?

    - Maybe here:

    - Try redownloading the app directly to the iPod by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store

  • I just upgraded to the 5s but the sales lady did not restore from my last backup with my 4s. How do I get my pictures and settings restored?

    I just upgraded to the 5s but the sales lady did not restore from my last backup with my 4s. How do I get my pictures and settings restored? I cannot seem to get it to give me that option. Can anyone tell me what to do? Thanks so much!

    If the phone has already been set up, you will need to go to Settings > General > Reset > Erase All Content and Settings to be able to go through the setup again. This time use Restore from Backup.
    This will walk you through the setup screens:

  • My  Macbook Air wakes up with a blank screen. Why do I have to shut down and start up to wake it up?

    I use Mountain Lion on a macbook Air. When it goes to sleep  it wakes up with a blank screen, I have to shut down and start up again to wake it up. Can anyone help?

    I had a similar thing on an old MacBook Pro where if I closed the lid, then reopened it before the sleep cycle took over, it would have a blank screen. I had to close the lid until the power light pulsed, then it would wake normally.
    Any similarities?

  • I can't download apps! Every time I try, it asks me to chose a security question and I try, but I just comes up with a blank screen and I can't choose a question. If I click no, I don't want to put security questions, it doesn't install the app. HELP!

    I can't do it! I am willing to add questions but I can't because it just shows me a blank screen. I even tried rebooting my entire iPad2 and that didn't work. I know it is not a certain app because I tried multiple ones.... HELP!

    •Tap and hold on the app.
    •When it starts to jiggle, tap the red  ⛔ in the top corner to close it;
    ***Please close all open apps on your phone***
    2) Tap Settings.
    3) Tap Safari.
    4) Tap Clear History.
    5) Tap the Clear History button.
    6) Tap Clear Cookies and Data.
    7) Tap the Clear Cookies and Data button

  • I can't connect my external hardrive to my MacBook Pro...

    I have a 2012 MacBook Pro - when I connect my Porsche external harddrive to it, it lights up but it doesn't show up on my Pro.
    If I connect this hardrive to another Mac it's fine. It used to work perfectly, which makes me think it's not a power issue. I have tried changing leads and changing ports to see if this rectifies the issue.

    From the Finder: Finder>Preferences>General. Check the box -External disks.
