  • Please help, my macbook pro is super hot, how can i fix it.

    please help, my macbook pro is super hot, how can i fix it.

    I am guessing you have just bought a new macbook pro,  I did the same thing when I first unpacked mine.
    You will get asked if you are using it on your lap, because they think that you are blocking the vents.
    the macbook pro will get really hot around the E R T and F keys and  I O P and L keys and the metal strip between the keyboard and the screen.
    I have found the graphics accelerator heats the machine up more than the actualy processor.
    you should report it to apple care before your 90 days is up, they may or may not send you to a genius booking.  Just incase you have issues with your machine later due to the heat buildup early on, that way they have a log of the problem.
    My macbook pro runs alot cooler than it did when i first got it, but still gets hot on heavy usage
    You shouldnt really worry unless it shuts itself down as then you have some serious problems, when it gets hot u should be able to hear the fans running and it will prolly keep the temp aroun 101-104 c under heavy load.   If you can't hear the fans, shut it down and take it back to the store.
    Hope this helps you

  • Since upgrading to Lion, my MacBook Pro is super slow connecting to Wi-Fi. Not so with Daughter's Snow Leopard or Wife's Dell.  Any ideas?

    Since upgrading to Lion, my MacBook Pro is super slow connecting to Wi-Fi (seems to search forever).  This is not the case with my Daughter's MacBook (still on Snow Leopard) or my Wife's Dell (Windows 7).  Any ideas?

    Hold Option when you click on the Airport in the top bar & post the stats.

  • Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight etc. It was fine before the upgrade and I have all the system preference set to "never turn off"

    Since upgrading to Yosemite my macbook pro keeps going to sleep if I am not using it. I want it to stay on as I leave it doing things overnight (cd's  / recording etc. It was fine before the upgrade and I have all the system preference set to "never turn off" - Help !!!

    Good advice from Linc Davis that should sort out your query i think...
    However you dont want to set your MBP to never go to sleep...
    Adjust reasonable sleep settings...
    And the download an APP called caffiene...
    When you click it you can have your MBP never go to sleep with a single click of your menu bar... and with another click it can go to sleep normally to maintain the laptop...
    Simply click the cup... To toggle never sleep/sleep

  • Ever since I installed Mavericks, my MacBook Pro randomly restarts.

    Hi all... this is my first time here, so please be gentle ;-)
    Ever since I installed Mavericks, my MacBook Pro just randomly restarts. It's been happening a lot, and I have zero idea of how to decipher the panic report. Can anyone lend an assist on this? Much thanks, in advance. Here's the report...

    Remove "Air Display" and see whether there's an improvement.
    Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
    Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
    I never install system modifications myself, and (unless otherwise specified in this comment) I don't know how to uninstall them. You'll have to do your own research to find that information.
    Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
    Back up all data before making any changes.
    You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
    If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
    WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    For earlier versions of OS X:
    Prepare Your Mac for Sale
    Boot from the OS X Installer Disc One that came with the computer.  After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.  After DU loads select the startup volume from the left side list then click on the Erase tab.  Set the format type to Mac OS Extended (Journaled) then click on the Options button.  Select the one pass Zero Data option and click on the OK button.  Then click on the Erase button.
    Note: You can skip the Zero Data option if you are not concerned about removing sensitive personal data from the hard drive.  If you choose to skip this part of the process then it is possible for others to recover data from the hard drive.  The Zero Data procedure will prevent others from getting access to your personal information.
    This process will take 30 minutes to several hours depending upon the size of the hard drive.  After formatting has completed quit DU and return to the installer.  Now complete the OS X installation.  At the completion of the installation do not restart the computer.  Instead just shut it off.  The next user will be presented with the Setup Assistant when they turn on the computer just as it would if new out of the box.

  • I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    It's almost impossible.  The new iMacs have a Target Display Mode, but it's built to do that.  Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15.  In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
    By the way, I found your answer by searching this forum.  I would suggest using the search function here in the futuere.

    i want arabic and engilish keyboard in MacBook Pro with retina display how can i order that ??, i want arabic and engilish keyboard in MacBook Pro with retina display how can i order that ??

    If you haven't found an answer yet. I know for a fact that this can be ordered directly from Apple at no extra cost
    You can either ask for this when buying a new MBP at a "physical" Apple store, or as in my case in the UK the online Apple store allows such keyboard configuration in addition to 3 other languages like Spanish, German and French

  • HT204022 If I delete my photo stream photos off of my iPhone will they also delete from my photo stream on my MacBook Pro? If so how can I ensure that those photos are saved?

    If I delete my photo stream photos off of my iPhone will they also delete from my photo stream on my MacBook Pro? If so how can I ensure that those photos are saved?

    They will not be deleted if they have been imported to your iPhoto library.  To ensure this happens automatically, go to iPhoto>Preferences>iCloud and check Automatic Import:
    To confirm that they have been imported to your library, click on iCloud on the left sidebar of iPhoto, open your My Photo Stream album on the right, then Control-Click on your pictures.  If you see "Show in Library" in the pop-up, the picture has been imported to your library and you can safely delete it from photo stream.
