HT3986 i installed win 7 on my mac book, and the sound driver was installed successfully, but i don't hear any sound, please help

i installed win 7 on my mac book, and the sound driver was installed successfully, but i don't hear any sound, please help

Is the volume muted? Click on the volume icon in the system tray to see if it shows as muted. If that's the case, I know of a workaround to fix this because if you unmute the speakers now, the condition will come back when you reboot your computer. I don't know the exact steps off the top of my head at the moment as I'm not in front of my machine. Check this first and reply if muting was the problem and I will detail the steps needed to fix the problem.

    I installed Lion on my MAC book and now want to uninstall it, can't seem to find a way to do it, any suggestions?

    In order to uninstall Lion and "downgrade" your OS, you have to erase your drive. There is no other way. If you have a bootable clone or a Time Machine backup, it is easy - just boot with it, erase the drive, and clone back. Or, do you have your install disks? Boot from that disk, erase the drive and reinstall.
    Make sure you back up your important files first since they will be gone.

    Not a virus, but it is malware: The Safe Mac » Search Results » adware removal.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
              Mac OS X Snow Leopard and malware detection
              OS X Lion- Protect your Mac from malware
              OS X Mountain Lion- Protect your Mac from malware
              About file quarantine in OS X
    If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
    From user Joe Bailey comes this equally useful advice:
    The facts are:
    1. There is no anti-malware software that can detect 100% of the malware out there.
    2. There is no anti-malware that can detect anything targeting the Mac because there
         is no Mac malware in the wild, and therefore, no "signatures" to detect.
    3. The very best way to prevent the most attacks is for you as the user to be aware that
         the most successful malware attacks rely on very sophisticated social engineering
         techniques preying on human avarice, ****, and fear.
    4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
        your computer is intended to entice you to install their malware thinking it is a
        protection against malware.
    5. Some of the anti-malware products on the market are worse than the malware
        from which they purport to protect you.
    6. Be cautious where you go on the internet.
    7. Only download anything from sites you know are safe.
    8. Avoid links you receive in email, always be suspicious even if you get something
        you think is from a friend, but you were not expecting.
    9. If there is any question in your mind, then assume it is malware.

  • HT2477 Just bought a Mac book and the set up is with the Voice over key commands,how do you switch this off as it is painfull to use and use the scroll pad

    Just bought a Mac book and the set up is with the Voice over key commands,how do you switch this off as it is painfull to use and use the scroll pad?

    It's the button (key) that is labelled Control.
    Each of the modifier keys and similar keys has its own symbol; this makes listing command keys easier to do. The Command key is usually the only key which has its symbol printed on the key. If you open Keyboard Viewer (in the Input menu, the one which displays the flag in the main menu bar), you can see what symbol refers to which key.

    Hi, Robert here, I moved to US from Singapore and I would like to switch itunes so I can purchase a book but I don's know how? Please help!

    I believe you mean to say that you wish to switch which country's iTunes Store you are accessing. Go to iTunes Store > Change Country (all the way at the bottom) to do this. You'll have to use up all of your iTunes balance to do this. Post back if this is not what you wanted to do.

    Hi,
    Apparently I'm Unable to install Photoshop CC because not enough space to extra on C-Drive... But I don't want it to extract there. I've already gone into "Preferences" and switched both folder locations (CC Files and App Files) into my D Drive which has plenty of space, but I get an error that there is not enough space on the C Drive. Duh, I know that, which is why I want to install it on another drive.
    What are some steps I can take to fix this?

  • My buddy tried to help me install windows 8 on my new mac book and all he did was put the disc in and now it will not come out and my mac book will not turn off

    I cannot get the windows 8 disc out of my mac book pro

    Force eject a stuck cd/dvd
    First try the normal methods to remove the disc. Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu.
    If you are running a virtual machine, e.g. VMFusion, ensure that the CD is disconnected from the virtual machine. This will sometimes allow the CD to now show up in Mac OS X.
    Shut down the computer and start up whilst holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared.
    If you have Toast Titanium installed on your computer, choose EJECT DISC from the menubar.
    Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder
    Open Disc utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button.
    Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism.
    Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray.
    If your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button.

  • HT3986 what is the risk to install windows 7 on mac book pro?

    what is the risk to install windows 7 on mac book pro?

    If you have back ups and follow apples instructions on using bootcamp assistant to install Win7, there is no risk.
    If you choose not to follow the instructions apple provides and have no back ups well then there is high risk of dissapointment.
    Just follow the instructions and you should be fine.
    Good luck.
    Edit:  Here's a link to the install instructions. Just choose the one for "Lion OSX". Should be the first one on the list.

  • Installing windows 7 on mac book pro late 2013

    Installing Windows 7 on Mac Book Pro Late 2013
    Background
    Mac Book Pro Late 2013 uses a USB 3.0 hub for the external ports, the keyboard and mouse devices.
    Windows 7 does not have the drivers to support USB 3.0 ports so these must be integrated into the boot.wim and install.win files so that Win7 can be installed and used on a Mac. If these drivers are not integrated when win7 is booted up then the mouse and keyboard will not function.
    Requirements:
    Two USB Flash drives
    Access to a Mac computer
    Bootcamp Assistant application
    Access to a Windows computer with windows 7 installed
    Windows 7 install disk or ISO file
    WinUSB application
    Windows Automated Installation Kit for Windows 7 (WAIK)
    Method
    On a Mac
    First prepare a USB Flash drive by formatting it using disk util app, found in Application Utility folder, to FAT format this will store the Apple drivers that can be downloaded from Apple using BootCamp.
    This will be called USB1
    Using Boot Camp Assistant select 'Download the latest windows support software from Apple'  to get the files from apple for win7 for your particular machine these will be downloaded and copied to the USB Flash drive called USB1.
    On a PC
    Using a PC download a copy of WinUSB from  www.joshcellsoftwares.com this software can create a bootable USB with the win 7 files copied on to it.
    Obtain a copy of Windows 7 either in DVD or ISO format.
    Using WinUSB and the Win7 DVD create a second bootable USB Flash drive. This will be called USB 2.
    About DISM
    DISM is a windows application that allows the editing of windows image files with the extension of WIM.
    If DISM is not installed on the PC it can be downloaded from windows website.
    To test to see if DISM is installed, open up a command prompt. Then type 'dism' without the quotes this will display the help description of DISM. 
    Drivers
    The apple drivers need to be added to the boot.wim file so that mouse and keyboard can function during the setup phase.
    The apple drivers need to be added to the install.wim so that mouse and keyboard can function after the setup phase.
    The video drivers are also added as it appears to cause problems if they are not included.
    Create a directory structure like this:
    c:\appleboot\
    drvrs
    mount
    win7x64install
    win7x64boot
    Create the following files in c:\appleboot\ with the following code:
    adddrivers.cmd
    color 0a
    dism /image:c:\appleboot\mount /add-driver /driver:c:\appleboot\drvrs /recurse
    ================================================================================ ==========
    mountboot.wim.cmd
    color 0a
    dism /mount-wim /wimfile:c:\appleboot\boot.wim /index:2 /mountdir:c:\appleboot\mount
    ================================================================================ ==========
    mountinstall.wim.cmd
    color 0a
    dism /mount-wim /wimfile:c:\appleboot\install.wim /index:4 /mountdir:c:\appleboot\mount
    ================================================================================ ==========
    unmountcommitfiles.cmd
    color 0a
    dism /unmount-wim /mountdir:c:\appleboot\mount /commit
    ================================================================================ ==========
    Copy the following files into their respective directories:
    Copy from USB 1 into drvrs the $WinPEDriver$ directory
    Copy from USB 2 \sources\boot.wim to win7x64boot directory, this will store the original file
    Copy from USB 2 \sources\install.wim to win7x64install directory, this will store the original file
    Then copy boot.wim from win7x64boot directory to the c:\appleboot\ directory
    Then copy install.wim from win7x64install directory to the c:\appleboot\ directory
    Once all the copying is completed then run the following cmd files in this order:
    For boot.wim
    mountboot.wim.cmd - this will mount the file for adding of drivers
    adddrivers.cmd - this will add the apple drivers to the mounted boot.wim
    unmountcommitfiles.cmd – this will commit the changes and unmount the boot.wim
    For install.wim
    mountinstall.wim.cmd- this will mount the file for adding of drivers
    adddrivers.cmd - this will add the apple drivers to the mounted install.wim
    unmountcommitfiles.cmd – this will commit the changes and unmount the install.wim
    Copy the files back to USB 2
    Copy the boot.wim and install.wim files from c:\appleboot\ directory  to USB 2 sources directory and overwrite the files.
    BOOTABLE USB
    You will now have a bootable USB Flash Drive that has the additional drivers needed to install Win7 on Mac Book Pro Late 2013.
    Mac Preparation
    On your Mac using Disk Util reduce the size of the partition of Macintosh HD so that there is approx. 80GB free for the use of Win7.
    Add a second partition, label it win7 and format it to FAT. This is so that win 7 setup can identify the correct partition.
    Installing Windows 7
    Insert USB 2 into your Mac and reboot, whilst holding the option key down.
    After reboot there will be three icons displayed one is the Mac operating system, the second is the recovery partition and the third is an orange icon indicating a bootable USB drive.
    Select this and win7 setup application will proceed to boot up with the keyboard and mouse functioning.
    Follow the prompts and when the drive selection appears select the win7 partition and format it to NTFS so that win7 can be installed. When windows setup reboots press and hold down the option key and select the windows partition so that setup can continue to install.
    After completion of installation of win7 insert USB 1 with the additional apple drivers. Goto the bootcamp directory and click on setup.exe file this will install additional drivers needed to use Win7 on a Mac.
    Once completed reboot your Mac and select windows to allow the drivers to update in windows.

    Yes this is correct that the /index:4 refers to the ultimate version of windows in mountinstall.wim.cmd
    dism /mount-wim /wimfile:c:\appleboot\install.wim /index:4 /mountdir:c:\appleboot\mount
    Users should do what applekryzzle suggested if you have a different version of windows. Thanks for the tip applekryzzle.
    With regards to the Intel(R) USB 3.0 eXtensible Host Controller drivers they are the ones that are provided by apple via boot camp assistant.
    These appear to work correctly and downloading as per instructions simplifies the procedure.
    For those that are interesred the updated drivers can be found here https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22824&ProdId=346 7&lang=eng&OSVersion=Windows%207%20%20*&DownloadType=Drivers
    I have also seen in other discussions that some users get black screens i believe that it is the lack of video drivers which is included in the download from apple using boot camp assistant.
    I'm certain that this works on Mac Book Pro Late 2013 models and i feel confident that this will work with other models.
    I will appreciate any feedback if this works on other models.
