Not sure what you mean by reset your MacBook. I would begin with Repair Disk
Insert Installer disk and Restart, holding down the "C"key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu(Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.TStatus of HDD at the bottom of right panel, and report if it says anything but<b>Verified</b>)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports diskis repaired.
If DU reports errors it cannot repair you will need touse a utility like TechTool Pro or DiskWarrior
Please do post back with further questions or comments.

    Your issue may not have anything to do with your files, it could be a corrupted cache file, reinstalling your OS and files from backup could be overkill and too much work.
    Run ALL of the free OnyX's checks, cleaning and maintainence aspects (not the log files) and reboot at the end.

    Your machine will act a bit slow until the caches and spotlight are rebuilt, but it should act faster
    Your next step is to use OnyX Verify Preferences and "show only corrupt plist" files
    If you find some, make a note of their location and remove then to your desktop and reboot and start the programs responsible, reset your preferences.

  • How can i reset my macbook pro without the disc?

    trying to reset a macbook pro to factory settings without a disc

    You can get a set of discs specific to your machine by calling Apple. Cost is about $20, I believe. Be sure and have your serial number handy.
    Then take a look at Thomas Reed's How to prepare your Mac for sale - that may not be exactly what you're doing but it will give your machine that factory-fresh feel.
    Good luck,

    Open iTunes... 
    If you're using iTunes 11 click on the box icon in the top-left corner to see the " Show Menu Bar " 
    and from the Menu Bar select Store...
    From the Store menu, choose Authorize This Computer.
    When prompted, enter your Apple ID and password, then click Authorize.

  • HT5624 How can I track the MACbook Pro that just used my apple ID to log into iCloud?  (I just got an email stating that someone just used it?)

    Here is the email:
    Your Apple ID ([email protected]) was used to sign in to iCloud on a MacBook Pro 13".  I had a MacBook Pro stolen in January and I'm wondering if someone was using that stolen computer to login??
    Anyway to track the computer trying to log in using my other Apple ID?

    If you activated the Find My iPhone service (in System preferences>icloud), then you can try to track it.  Using another computer's browser, log into icloud.com and look at the Find My iPhone page.  On a device, invoke the Find My iPhone app (get it for free at the itunes app store) and log into the icloud account.  Note:  The Find My iPhone **app** does not turn on the service, you can only do that through Settings>icloud.
    If the mac is listed as "offline", then you can't track it.

  • How can I use the MacBook Pro webcam with Windows XP apps under Parallel?

    Thank you in advance for your help with this matter.
    I have a MacBook Pro and I have just installed Parallel with Windows XP. I would like to use the webcam that comes with the laptop for applications that run under Windows XP (ex.: PalTalk).
    The application doesn't seen to recognize the camera. Do I have to load the drivers for this camera in XP? If so where can I find them and what is the process?
    Thank you again,
    Enrico

    You probably need to load the Boot Camp drivers that are on the Leopard DVD. Whether it works or not I can't say, but you may want to post your question on the Parallels forums, since it's not an Apple product, and if anyone has gotten it to work you'll find them over there.

  • How can i zoom the macbook pro retina camera?

    system preferences has no camera or video config and FaceTime preferences are dimmed for the new retina...  I want to create a video conf call in a conf room and need to zoom out. nothing I can find on the apple site discusses this...  thanks if you can help!
    p.s. tried using a 2-3 year old logitech cam thinking that the options to zoom i see on a PC might be available on the mac, but the camera is not recognized by the Retina.

    At startup I get grey screen and a folder with a flashing question mark.  How do I reset my MacBook Pro to the manufacture defaults?

    Click here and follow the instructions. If the computer originally shipped with Mac OS X 10.6.8 or earlier, when you reach step 5, insert its original disk, restart with the C key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.

  • How can I reboot my macbook pro to how i first got it if i don't have the cd

    How can I reboot my Macbook Pro to how it was when I first got it if I don't have the cd

    I had to do this the othe day when  I got my mew retina and set it up and then tried to transfer data from my old mac instead of using migration and made a real mess of it.  And I wanted to start all over again, so I called apple help and they said this:
    Basically what you do is wipe the hard disc clean my reformatting - thats a scary bit
    then reboot holding alt down and you get an option screen
    you choose intalll Lion and it comes in via wifi and takes 2 hours or so , and then its just like an out of the box computer.
    Best look for through some threads to double check the method, but thats basically what I did and it was fine.
    Obviously cos the retina doesnt have a dvd drive, it had to be the only way anyway.

    By default, the first command will return a Shared entry and one with an username on it. Supply that username.

  • How can I reset the screen colors/resolution on an old white macbook?

    My screen shows neon colors and a zigzag shapes.  How can I reset the color resolution?  This laptop was supposedly fixed but when returned all my data had been "lost".  The certified mac tech said he reinstalled the OS but lost all my desktop files and HD and couldn't recover.  ODDLY, when I started the machine and started fresh, my old hard drive was still there!  Although he'd wiped out my current desktop files- gone.  But, the  screen colors went wonky all of the sudden and I don't know how to resert or correct the resolution.  Can any one share a suggestion?

    With that kind of issue after returning from a repair where a tech was inside the computer, it should be returned to the same place for an evaluation of the problem, a diagnosis, and perhaps they need to check their work to see if something came loose while they had it apart.
    The System Preferences> Displays has a panel to select settings.
    You may have to try & see about a reset of System Management Controller http://support.apple.com/kb/HT3964 Or, if reset of NVRAM  http://support.apple.com/kb/HT1379 may help. Not sure if these would do anything if there is hardware damage.
    Good luck & happy computing!
