Then you have no Recovery HD. You will need to do the following:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Need help now please. macbook wont start up
I have a white macbook.
I was using it yesterday and the computer just shut off. I went to restart it and it does the chime, goes to the apple screen and just as the little circle under the apple spins, the laptop totally shuts down. it will not start.
I have tried to reset the pram and that didn't work. I just installed 10.6.4 yesterday....
Please help. I need the computer for work today.
Thank you.First thing to try, is booting from the restore DVD and installing a fresh copy of 10.6. If you're lucky, the 10.6.4 update just hosed your OS install, and a simple reinstall is all that's needed.
Once you've booted to the 10.6 installer, it couldn't hurt to run Disk Utility from the Utilities menu to verify the SMART status of the drive, and even run a repair disk operation on it.
If the SMART status is failed, or Disk Utility doesn't see the drive, then you're looking at a hardware failure. You'll need to take it somewhere to be fixed if it's under warranty, otherwise if you have some precision screwdrivers like a PH000 and Torx T4, you can replace the drive yourself with pretty much any 2.5" SATA drive. -

Help me please, Reader wont start!
Very wierd situation - Acrobat Reader would not start when I try to open a pdf file, instead heavy harddrive usage starts immediately, my PC hangs for some time and all of this goes on and on until I kill AcroRd32.exe process in Task Manager. After that heavy harddrive usage stops. This was going on with version 9 and recently I uninstalled it and installed Reader X hoping that this will solve the problem but the behaviour is exactly the same! I also have an old Reader version 5, that one still works OK. But being old version I am constantly getting messages about new features that could be present in new pdf files.
Anybody has a clue what is going on with my Acrobat Reader X and how to fix it?Hi guys
My question has not been answered. But I've got some additional information. What I found out is that the problem is somehow linked to my local user profile! If I create another user and login as that user any version of Acrobat Reader starts up just fine. Also, if I login as myself but start Adobe Reader under another user using "Run as..." again it starts up no problem.
What could be the problem?

I have a macbook pro and on accident deleted ichat but reinstalled it using the cd, when my buddy list comes up, i try to double click my buddies name to start a chat and nothing happens. i could receive instant message but cant start my own or reply. someone please help!
Hi,
DId you download and Install the COMBO version of the last Update that you did ?
iChat on the Install Disk is likely to be several versions behind where your OS has been Updated to.
It needs to Match the OS level.
iChat Updates come in the OS Updates.
You need to run the Updater manually as Software Updates keeps records of what it has done and thinks iChat is up to date.
If you are on Snow Leopard then the COMBO version of 10.6.7 is here
If you are on Leopard then the COMBO for 10.5.8 is here
Googling Mac OS X 10.x.x COMBO where x.x is the version you are up to will generally find the link to the right page if you are at a different OS version.

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now. -
Hi there, I bought an iPhone 4s (sprint USA) from eBay. Now i cant active the phone here in UK. How can I active this phone ? Can anyone help me please.
Why on earth did you purchase an American iPhone if you knew you were going to activate and use it in the UK?
If you like in the UK and you want to use the phone in the UK, then buy an iPhone 5 that you can actually use in the UK.
So you need to purchase the phone either through one of the phone companies of your choosing by taking out a contract - so EE (Organge and T-Mobile 4G), Vodafone, 3, or o2 or buy an unlocked iPhone directly from the Apple store itself for full price.
If you buy from e-bay you have no valid warranty if the phone goes wrong, so you won't be able to get the phone fixed in the UK, but you will physically have to go back to the US to get it fixed - iPhone warranty is country specific and NOT worldwide. If you buy the phone in the UK, then you will have an EU warranty.
Return the phone to your seller at e-bay for a full refund and start again and buy and iPhone 5 that is unlocked from the UK and then you will be able to activate it.
Do you have a sim card because you need a sim card to be able to activate a phone and have you connected it to iTunes?
Unfortunately, not all US models of the iPhone 5 have sim card slots or if they do, they are not all unlocked, so if this is the case with your phone, then you won't be able to activate it here in the UK and there is nothing that you can do. You will either have an unusable brick or you will have to return you phone to your ebay seller for a full refund. -

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace -
please does anyone knows how to delete the "others" on the iphone becuase it take me a lot of spaace and i cant have anything i have 5 GB of othres coan some one help me please?
If restoring using your backup didn't work, you'll have to save as much of your data as you can (import your photos to your computer, sync your contacts and other data with iCloud, email things like Notes and Voice Memos to yourself, sync with iTunes to transfer all your purchases, etc.) and then restore it as new without using your backup.
