How do I get mac to only recognise my tv monitor when it is switched on?

For example when my tv is switched off the cursor would be lost for a bit as it would be where the tv is. Also sometimes some windows would open in the tv monitor so to access it i would have to first turn the tv on. Is there a away for the mac to detect which external monitors are switched on so the cursor stays in the desired area?
Thanks

The Mac uses a highly-parameterized display Driver, customized for the actual capabilities of the display. The settings are determined by a query to the display at power-on, when the Mac queries every attached display. The display name is also reported.
System preferences > Displays > (Detect Displays) ...
... replicates the query to update what displays are present and their names and capabilities. So using that command when the display state is changed off to on or on to off should adjust the configuration to current state of things.

  • How can I get my exchange account recognised by my home mac?

    How can I get my exchange account recognised by my home mac? I got absorbed into the Mac world as I was given an iPad at work. I am having problems getting my work account synced with my new iMac at home. I work with Exchange at school and gmail and yahoo at home. I'd like to have my notes, agenda, contacts and Exchange account in sync... ¿Es poslble?
    Thanks!

    Depends what OS X and Browser you are using?
    If you are on Snow Leopard (10.6) and Safari (5.1.7) then open Safari Preferences, select the General tab and make sure that:
    1. Safari opens with: A new window
    2 New windows open with: Homepage
    3. Homepage: is set to the desired https: site

  • How do I get Mac App Store on my computer? I have 10.5.8 OS. If I need to upgrade first how do I do that? It says that my software is updated.

    How do I get Mac App Store on my iMac? I have 10.5.8 OS. If I need to upgrade first how do I do that? It says that my software is updated.

    And once you get Mac OS X 10.6 installed, update it to at least 10.6.6 which was the first version to include the Mac App Store (the latest version is 10.6.8). The DVD you get will almost certainly be only 10.6.3. You can update from 10.6.3 to 10.6.8 via Software Update, or you can download a standalone Combo updater (Support tab above, then Downloads).
    Regards.

    Not sure which driver you mean when you say "the driver in the Mac's list". Apple does not provide a driver for this device, so if you mean one of the default printers that are included with 10.6, like the Generic Postscript or Generic PCL, then these will only work if the optional PS or PCL print kits were installed in the machine. Given your inability to print then it would seem that you have neither kit installed. So this would require you to install the Canon UFR2 driver, which you can obtain via this link.
    With the UFR2 driver installed, you add the printer using IP > LPD. Enter the IP address of the iRC2380, leave the Queue name blank and change the Name to iRC2380. Leave the Location field blank and in the Print Using menu, browse to the "Canon iR C2380/2550 UFR II (UK)". Click OK and then Add to complete the queue creation. You should now be able to print. Please reply if it does not work.

  • HT1435 how do i get i tunes to recognise my i pod 4th generation

    How do I get I tunes to recognise my i pod shuffle 4th generation,as I keep getting fault message (2005)

    Hello there, CliveFromBR.
    The following Knowledge Base article covers the issue you're having with error 2005:
    iTunes: Specific update-and-restore error messages and advanced troubleshooting
    http://support.apple.com/kb/TS3694#error2001
    Specifically the following:
    Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)
    If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related to conflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.
    Thanks for reaching out to Apple Support Communities.
    Cheers,
    Pedro D.

  • How do I get my iPad to recognise printer hp 1217nfw, I have a d-link router?

    How do I get my iPad to recognise my printer hp 1217nfw, connected with a d-link router?

    Don't know if you ever got this figured out but here is the answer...
    I just spent the last two days on this and have finally sorted it out. It actually isn't that hard to do but for some reason, no one has consolidated the information in one place!
    First and foremost, make sure that you have all the latest and greatest firmware updates for your printer, your computer and your mobile devices.
    Next, you need to connect your printer to your network via an ethernet cable, this is the only way to get in to the printer softare to configure it for your wireless network.
    Navigate the printer menus on the keypad to Reports>Config Report and print this report. It will provide you with the IP adress and IPv4 address for the printer.
    With the printer connected to your network and powered on, point your browser to the IP address of the printer. If this doen't work (it didn't for me) use the IPv4 address.
    This will open the configuration panel for the printer and will let you configure the wireless for the printer so that it can join your wireless network. You will see various tabs across the top. Select network. Then along the left you will see wireless. Choose that. Now you should see a list of wireless networks available including your very own home network. Choose that one, enter your password and hit apply.
    Disconnect the ethernet cable and you should be ready to Airprint from all devices. This worked for me, I can't imagine it won't work for all...then again...

  • How can I get my IMac to recognise the scanner part of the HP printer/scanner?  It prints!

    How can I get my iMac to recognise the scanner part of the HP printer/scanner?  It prints!@

    I had a similar problem right after the first update to 10.6.7, which happened to quite a few people.  It took a couple of software updates and then an HP printer update to fix it.  So make sure that all your software updates are up to date.   Mine is an older printer: C6280 All-in-one but scans fine now that my mac recoginises it.  You might want to check on the HP site also.
    It was really frustrating because it had worked fine before.

  • How do I get my ipad to recognise my pdf attachments as pdfs?

    My ipad does not always recognise a pdf file as as incoming mail attachment, so I cannot always open the pdf in another app.
    Although the attachment shows as a paperclip in the mail header, sometimes the content of the attachment is displayed in the body on the email. When this happens I don't get the small square window at the top right corner of the screen where you can select another app to open the pdf.
    How do I get my ipad to recognise my pdf attachments as pdfs and not show the content in the body of the mail message?

    This is from page 44 of the iPad User Manual:
    Open a meeting invitation or attachment: Tap the item. If the attachment can be used by multiple apps, touch and hold to choose an app that works with the file.
    Based on this, I suggest trying this:
    Touch and hold an area of the PDF file that displays in the body in your email.  Do you get the behavior described in the manual above?

  • Editting PDF documents that were created by a MAC doesn't work because of font incompatability.  How can we get MAC fonts and load in our Adobe Acrobat Pro 9?

    Editting PDF documents that were created by a MAC doesn't work because of font incompatability.  How can we get MAC fonts and load in our Adobe Acrobat Pro 9?

    If it's a Mac font and you're on Windows, you can't. If you are also on a Mac, you'll need to purchase the fonts (fonts are generally non-transferable, like software. One of the reasons pdf exists), install them and try your edits.
    But it's best to edit the original document and create a new pdf when finished.

  • How can I get Mac mail to open winmail.dat attachments on lion 10.7.3

    How can I get Mac mail to open letter attachments winmail.dat??   (Lion 10.7.3) Any help appreciated...

    Sorry peterskine,
    it's true in part. There's more then one article on the subject "Recipients receive a winmail.dat attachment":
    http://office.microsoft.com/en-gb/outlook-help/recipients-receive-a-winmail-dat- attachment-HA010153018.aspx?CTT=1
    The odd thing is that my colleague and me use the same release mountain lion and we received the same email from someone on Outlook2007. He received the mail with the attachment, whilst I saw a "Winmail.dat". It already happened to me on snow-leopard, some month ago. Up til today I don't know what the difference between our machines is.
    But it is interesting: the same OS, the same mail-clients (Apple Mail) and still different results.
    Note: on my machine it used to work properly. It just suddenly happened that I started to receive winmail.dat files in stead of proper attachments.
    When I have more time on hand, I cant try to find out why this happens.
