Also, when I am going to option, the system doesn't allow me by saying hard disk is locked. Kindly help out

OS X- Gray progress bar appears under Apple logo during startup
I suggest you need to erase your drive and reinstall OS X. Be prepared for the possibility that your hard drive has failed.
Install or Reinstall Mavericks or Mountain Lion from Scratch
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.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Hello tsnovak!
Is English your first language? If not, I can help get someone who can speak your language to translate this article.
Tsnovak, you seem to be on a Apple Logo Loop. This has happened with several iPod generations. Contact Apple Support here: <https://www.apple.com/support/contact/>
Thanks!

You could try removing the sim card and cleaning it - then put it back.
I assume that there is supposed to be a sim card in your model of iPhone 5 ?

If your device has been jailbroken during the warranty, Apple will not service it.
Maybe you missed that in this article:

If you have music that was purchased on different iTunes accounts than the one you use, then you must provide the password, otherwise the tunes are not considered yours. You can turn off iCloud and just use the usual USB sync method. But I wonder whether you'll have the same problem?

Hello, I have a Macbook Pro 17'' 2.4 GHz Intel Core i7 (2011). I dont know what happened but the pixels on black or dark areas on my monitor are displayed in a flickering red color, and on white areas are light blue. Any idea??

Hello,
I have a Macbook Pro 17'', 2.4 GHz Intel Core i7 (late 2011). I dont know what happened but the screen shows red flickering pixels everywhere where it should be black, and light blue pixels where it should be gray, I had this problem twice, the first time it just disappeared by itself. Now it's been like this for days, I have really no clue.
Anyone with the same problem or solution?
This is how it looks like:
Thanx

Is that a camera picture or a screen-shot? Is there any difference? i.e., can you capture the problems in a screen shot, or not?

Update: An Apple rep called me today to update the status of my return. I was told that the replacements for the BLACK iPad 2's was still another 3 weeks out (at least) so they offered me a brand new WHITE 16GB iPad 2. I could have that or continue waiting. I opted to go ahead and accept the offer of a new white one. Worst case scenario if I don't like the white one I have buddy that just bought a 16GB black one that he would be willing to swap it.

After loading mavericks Facebook will only load once in a while. Usually the blue bar goes half way and just stops and does nothing. Never had a problem before I updated.

When my Itunes Match tries to update, it stalls every time on the third step "Uploading remaining songs and artwork". If I don't cancel it, very shortly I get a message saying "Itunes has stopped working" and then Itunes shuts down completely. Is there a fix for this? I have the most recent version of Itunes. HELP!

Tried to take out the nano sim as i though it will be turned off but it has not been! i dont know what i can do and i am desesperate!!! thanks All for your help!!

Removing the SIM has no affect on the power of the phone. It is just the part that facilitates connecting to your carrier. Try holding the sleep/wake and home buttons together until you see the Apple logo on the screen and then release the buttons. The phone should reboot. You may need to hold the buttons together for 15-30 seconds.
