Hello, I have a MacBook Pro from 2011 and I accidentally while playing around with it deleted everything off my hard drive and I need to know how I can re install an operating system. Would I have to download it.

Someone please help me
I'm not sure what I should do to re install an operating system would it be possible to install mavericks
I don't have the operating system backed up

That's not good. OS X Recovery requires a high speed broadband connection as noted here > About OS X Recovery
Check your download speed here >  Speedtest.net - The Global Broadband Speed Test

  • I have bought a new Mac Book Pro, and I need to know how I can move Aperture from my old Mac Book to the new one..

    I have bought a new Mac Book Pro, and I need to know how I can move Aperture from my old Mac Book to the new one..

    It begins with: F-285-NER-151-QBQ-and continues with 5 more 3 or 4 letters/numbers..
    Yes, that is the number. And what version of Aperture have you installed? The same version as on your old Mac?
    But it don´t work on my new Mac...
    In what way does it not work? Does it require you to enter a licence number for Aperture 2 as well? That will be necessary, if your serial number is an upgrade serial number. Then you will have to enter all previous numbers as well.
    Or does Aperture not accept the number as correct? Then check the spelling; some letters are easily confused like "I" and "1" and "O" and "0". Do not use the number pad to enter the numbers.
    See: Troubleshooting Professional Application Serial Numbers

    HI,
    Welcome to the    Support Communities
    It really depends on what you have done so far.
    The Simplest is to open iChat go the word iChat in the Menu Bar (Drop Down Menu)
    Select Preferences.
    In there select Accounts.
    Highlight any account in the list you no longer want (you can't delete the Bonjour one)
    Once highlighted press the minus button at the bottom of the list.

  • Macbook pro 15'' 2011 will not charge while playing games under win7 64

    During the game (under high load ex. crysis2), the charging LED changes from orange to green and the computer does not charge,
    even the battery drains slowly. If battery charge is 100%, in about 50 minutes after the start of the game, the battery charge drops to 94% and
    when I quit the game the charging LED changes from green to orange... What's the deal?  (Sorry for my english, i'm italian ).

    I've just bought a 17" MBP and I'm having the same issue, but in OSX and Linux just the same.  In one incident, my battery was running low so I plugged it in, but it still died about 10 minutes later because it continued to draw more power than the Magsafe plug could provide.  Needless to say, there was quite a bit of filesystem corruption from the sudden power loss.  That this is a common issue to 2011 MBPs does not magically make it "acceptable", especially when the fix consists of providing a more powerful charger.
    For a $2500 laptop this is absolutely ridiculous.  If the thing draws 100w under peak usage, make a damned charger that provides 120w.  In the worst case, it will keep the computer running without unduly stressing the battery.  In the best case, it will charge the battery much faster.

  • I have a Macbook pro mid 2011 and just bought the Apple TV. While watching program or movie from any of the apps such as Watch ABC, the program keeps stopping and starting constantly.

    That would indicate a network issue.
    Reboot ATV and router
    Make sure DNS is set to auto
    Ensure router is up to date, if on wifi try ethernet
    Go to istumbler.net to get a report of the network, look for signal strength and noise

  • I have a MacBook Pro Late 2011 and I'm wondering if I install Windows 7 Ultimate to this MacBook Pro with this Full Retail Version. And if so, which bit to use either 32-bit or 64-bit since I have both disks.

    I have a MacBook Pro Late 2011 and I'm wondering if I install Windows 7 Ultimate to this MacBook Pro with this Full Retail Version. And if so, which bit to use either 32-bit or 64-bit since I have both disks.

    64 bit.
    32 bit won't use all your computer's ram.
    64 bit allows you to run 32 bit programs
    Your computer is 64 bit
    New programs use 64 bit.
    There is no reason to use the 32 bit version of Windows.

    I don't know who/what Indira Budiman is, but you can contact iTunes Support via this page : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption
    If it's an app then does it allow you to make in-app purchases within it ? If it does then you can turn off in-app purchases via Settings > General > Restrictions on your device.

    You need to purchase an external drive and start moving some files to it or you can try trashing some files that you no longer need.
    Download OmniDiskSweeper and see where your larger files are... you can move them to an external drive or trash them: it's up to you.
    I would also begin, since it's obviously don't have backups, a backup scheme or two. See Most commonly used backup methods.
    Good luck,
    Clinton
