  • I have a new Macbook Pro. It won't join the wireless networks that my old Macbook Pro joined; only some of them (I'm talking open networks). What can I do, please?

  • What is the most current MacBook Pro model that has a Matte screen?

    What is the most current MacBook Pro model that supports a native Matte screen?
    I love Mac's but due to substantial eye strain with the glossy screens, I must use a Matte Screen laptop. Many thanks!

    There are none in production at this time.  I suspect it was the 15" 2012 model.  I do know the 2011 15" and 17" MBPs had that option.
    Ciao.

    What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

    Hello Alex,
    It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    When using an external display be sure to check the following:
    If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    Monitor and Display Adapter Table
    About Mini DisplayPort to HDMI adapters
    Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
    Thunderbolt ports and displays: Frequently asked questions (FAQ)
    Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    Try unplugging the video adapter or cable and then plug it back in.
    If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
    Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
    Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    Cheers,
    Sterling

  • HT1338 hi what antivirus is best in macbook pro???and may mac pro is go slow?

    hi what antivirus is best in macbook pro???and may mac pro is go slow?

    Forget about viruses, and don't install Sophos, which is worthless.
    First, back up all data immediately, as your boot drive might be failing.
    One possible cause of a slow user interface is a large number of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.
    Otherwise, take these steps when you notice the problem.
    Step 1
    Launch the Activity Monitor 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.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    You must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
    Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into a message.
    Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

  • I got a CCTV camera. On the side is says 'NATIONAL CCTV LENS 8mm F1.2. Can I connect that to my macbook pro? How?

    I got a CCTV camera. On the side is says 'NATIONAL CCTV LENS 8mm F1.2' can I connect that to my macBook pro? How? I'm doing a project and I need to connect the camera to my Macbook pro. I also need to be able to see what the camera sees at the same time. How do I dont this? PLEASE HELP!!!!!

    It depends on what connections the camera has. If it has USB, just plug it in. If it is networked, put the camera on the network and then access it from your Mac using whatever software or browser access is directed by the camera instructions. If it has a purely video or analog connection (coaxial, RCA, etc), you will need some kind of video interface in addition to the Mac.

  • What is the difference between MacBook pro 2011 and 2012

    What is the difference between MacBook pro 2011 and 2012

    understanding that at the time of the question, there has not been any Macbook Pro 2012, now it is later and there is.
    The difference is:
    -CPU being used (2011 models: Sandy Bridge, 2012 models: Ivy Bridge)
    -Graphics (2011: intel 3000 + on 15"/17" ATI, 2012: intel 4000 + on 5"/17" nvidia Geforce 650M)
    -USB (2011: USB2.0 only, 2012: USB3.0)
    -Bluetooth (2011. 2.1 + EDR, 2012: 4.0)
    Ivy Bridge CPUs are smaller and are a little bit more energy-efficient.
    Other than that, currently the devices are not much different in respect to performance (Apple's graphics driver performance is known to increase during upgrades, though, so the performance gap may widen up)

  • S apple coming out with a new version for Macbook Pro MD101HN/A ? what should i go for Macbook Pro or Macbook air since my usage are basic mainy internet , word , excel , powerpoint etc.

    Is apple coming out with a new version for Macbook Pro MD101HN/A ? what should i go for Macbook Pro or Macbook air since my usage are basic mainy internet , word , excel , powerpoint etc.

    souvikfromKolkata,
    you’ll know as soon as the rest of us do if Apple decide to produce a new non-Retina model. My guess would be that they won’t do so, but that’s only a guess.
    With Internet, Word, Excel, and PowerPoint representing your main usage, either a MacBook Pro or a MacBook Air would be suitable for you.

  • What configuration of the new macbook pro do I need to run FCS 3 without choppy playback.

    Yep, just wondering what configuration of the new macbook pro do I need to run FCS 3 without choppy playback or lagging.  I'm thinking about the 7200rpm, 2.2ghz, antiglare, 4gb ram, with 1gb GPU graphics card configuration

    Nothing wrong with the computer. Playback is dependent on the media and the drives.

  • What is the problem on MacBook Pro retina 15"?

    I just bought a new MacBook Pro retina 15". After unboxing, I turned it on and there was no any problem. But the second time I turned it on and charge battery, I got 2 problems, 1. The machine made noise loudly and 2. The charging is not working. What is the problem on MacBook Pro retina 15"? However, after about 1 hour, it works normally. Should I still use it or sell it before it has more issues?

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

  • Within the last hour, I noticed that my older MacBook Pro, while I was playing it in iTunes, lost contrast on the screen.  I am sorry, but I did not take exact notes on this event.  Around the same time, I did do a back up, uploaded software, etc.

    Within the last hour, I noticed that my older MacBook Pro, while I was using iTunes, lost contrast on the screen.  I am sorry, but I did not take exact notes on this event.  Around the same time, I did do a back up, uploaded Apple software, etc.
    I'm using two MacPros simultaniously, the old one for iTunes, and the new one for the other things.  My new one has no problems, so am wondering if there is an easy way to correct the older MacPro's contrast problems.  The computer is over three years old, and I'm wondering also if this failure is an aging sign.  (I also have other problems, such as a noisy DVD drive, which is part of the reason I bought a new MacBook Pro.)

    Is the older MBP a pre-Unibody model from early 2008? If so, it could be having this problem:
    http://support.apple.com/kb/ts2377
    If so, you would be entitled to a free repair.
    The lost contrast could be considered distorted video.
    Do you have an external monitor? If the external shows the same lost contrast, the graphics chip is likely the culprit. If the external is OK, then you probably have an issue with the built in display or possibly with its connections.
    You may also want to check in Universal Access to see if the contrast bar is set in its normal position (all the way to the left).
    Apple has a special test they can run to diagnose the NVIDIA issue, so if you have access to an Apple Store, make an appointment at the genius bar to have it run.
    Good luck!

  • What is the value of MacBook Pro 17 inch 160 GB?

    What is the value of MacBook Pro 17 inch 160 GB?

    You can try one of Apple's recycling partners to see how much they'll offer for it:

    But you are likely to get more for it on ebay or craigslist.

  • How to know Apple Id associated with that perticular device (Macbook Pro)?

    Hi experts there...!
    How to know Apple Id associated with that perticular device (Macbook Pro)?
    How to change the Apple Id associated with the particular device?
    Okay now the scene is that one of my friend gave me macbook pro as a gift, now we both dont know how to change the associated Apple Id with this Macbook pro. He has his apple id and password which works perfectly with this macbook. But we want to change associated apple id with this macbook. After changing the apple id will it be possible to update mountain lion or to reinstall online completly? Does this process completely disconect from previous apple id and connect with new apple id?

    Welcome to Apple Support Communities
    If your friend's Mac didn't come with DVDs, he has to call Apple in order to deauthorize his Apple ID from the Mac > http://support.apple.com/kb/HE57
    After that, you will be able to register the MacBook Pro with your Apple ID, and you will be able to install OS X, iPhoto, iMovie and GarageBand for free. After doing that, you can erase the hard drive and reinstall OS X, so everything from his Apple ID will be removed
