Hello i installed windows 7 on my mac and after installing it i gan't go back to mac os x

Did you use Boot Camp Assistant?
You should be able to hold down the option key whilst booting in order to select which OS you want to boot into.

  • Installing Mavericks cause Kernel Panic and after installing too

    Hi,
    I worked with Mountain Lion and all was good, but I thought that would be nice to update to Mavericks.
    And I'm not good in Mac OS, so I didn't prepare backup before, because believed that it have to work.
    But during installation I got kernel panic several times, yeah. But installation process was continued and finally Mavericks was installed.
    I was happy, but I shouldn't.
    From time to time I'm getting kernel panic and I don't know what is reason.
    The worst things that I can't rollback to ML, because for some reason Mavericks installing instead.
    And I did clean install several times, and did cleaning NVRAM and PRAM, but it all didn't help to me.
    I haven't Apple Support in my country, so I can't even come to service center.
    And my last hope is your support.
    Could you please look on a kernel panic log and say me what is wrong with it?

    Hey, I am unable to install windows 7 using 'bootcamp 5.0' . I have already partitioned the drive as (mac Os Extended Journaled) and yet it seems bootcamp won't acknowledge this?
    My first thoughts were that 'bootcamp' was out of date...needed an upgrade to register windows 7. Since then I am once again met with the same problem... how can it not see the I have already have a paritioned drived ready to be used for installition, is there a way to fix this problem? I don't really want to pay out for 'i-parition' only to merge my 2 drives back into one and start again from scratch =/. Seems silly to do so...what are my options?
    Regards Swishi...p.s If anyone can help me...it'll make my day :3.

  • Hello i have a problem with my MacBook Air they wiped out the operating system then installed windows 7 how do i re install the apple firmware

    Hello i have a problem with my MacBook Air they wiped out the operating system then installed windows 7 how do i re install the apple firmware please help

    That is incorrect. You can install Windows on a Mac, any Mac, without having OS X installed on it.
    To the OP you will need the original system reinstall USB thumb drive that came with your Mac Air if it is older than a Mid 2011 model or if it is newer than a Mid 2011 model you use the Online Internet recovery system.
    If you don't have that original reinstall USB thumb drive you can order one from Apple for a small charge. Call Apple and ask to speak to someone Specifically to order a Replacement USB system reinstall thumb drive for your model year. You will need the serial number of that Air. It is etched into the bottom of the case.

    You can't run Windows on your Macbook Air without having Mac OS X installed with Boot Camp.  So it should be an option to select the Mac OS X partition at startup when holding down the option key.  Take a look at this link, http://support.apple.com/kb/HT4818

    I don't think this will fix your problem with restoring your iPhone 4 though. That is likely a seperate issue.
    but i can do it with any windows?
    Yes, you can theoretically restore your iPhone with any computer running the most current version of iTunes (10.6.3) unless there is some other issue.
    I get error code(21)
    According to this support article: http://support.apple.com/kb/TS3694#error21:
    "These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service."
    Do you run any anti-virus or third-party firewalls on your computer? Try disabling them and trying the restore process again. It may be possible that one of these security applications is interfering with the iPhone's ability to authenticate with Apple's servers.

  • Is there any way how i can download and run Window based games, with out installing Windows-thus Bootcamp? and if so, is it free?

    is there any way how i can download and run Window based games, with out installing Windows-thus Bootcamp? and if so, is it free?

    No, you must install Windows to run Windows software. You do not need to use Boot Camp (yes, it's free because it comes with OS X.)
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    Install the Apple Boot Camp software.  Purchase Windows XP w/Service Pak2, Vista, or Windows 7.  Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows.  Boot Camp enables you to boot the computer into OS X or Windows.
    Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7.  Parallels is software virtualization that enables running Windows concurrently with OS X.
    VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7.  VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    CrossOver which enables running many Windows applications without having to install Windows.  The Windows applications can run concurrently with OS X.
    VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris.  It is not as fully developed for the Mac as Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
